All available Counter-strike 1.6 and Half-Life game cvar list.

You will learn what each cvar command means because there are a lot of cvar settings for counter strike 1.6 game, we will introduce and help you understand what is what.

These CS 1.6 cvar settings lists can help you improve the quality of your shooting and the game itself. Well-chosen settings will help you have an advantage over your opponents as well.

CVar name	Description
allow_spectators	Allows players to join as spectators.
ati_npatch	Enables ATI TRUform technology, which will result in higher quality models but lower performance.
ati_subdiv	This is ATI TRUform level, the higher you go (with ati_npatch set to 1), the more polygons are added to the models to smooth them out.
bgmbuffer	Sets the allocated memory for CD/MP3 music in kilobytes.
bgmvolume	When disabled, it pauses the current audio that is being played with the “mp3” or “cd” command. To unpause, simply re-enable.
bottom color	Sets the bottom color of your Half-Life model that others see.
brightness	Sets the brightness value.
cam_command	Enable third person view. This is the same as the “third person” command. HL does not require sv_cheats 1 to work.
cam_contain
cam_idealdist	Third person camera distance. See cam_command.
cam_idealpitch	Third person camera step. See cam_command.
cam_idealaw	Third-person camera yaw. See cam_command.
cam_snapto	If enabled, your viewpoints will move at the same speed as your movements, not faster than your movements. Third person only. See cam_command.
Chase_active	This is a 3rd person view just like cam_command 1, except that it only works in single player, and when you move your mouse, it’s like zooming in on your player model.
Chase_back	Sets how far the camera is behind you when Chase_active is 1.
Chase_right	It sets how far the camera is to your right when Chase_active is set to 1. If you want to make the camera to your left, use negative values.
Chase_up	Sets how far the camera is above you when Chase_active is 1.
client port	Sets the port through which the client connects to the server.
clock window	It is designed to combat the speedhacks used in the game. The default value for this cvar is “0.5”. As the value decreases (0.3, 0.1, 0.01, etc.), modem client games should feel twitchy. The clock window setting does not affect the server. Now this doesn’t block speedhacks, it just makes the speedhacker fall far behind when speedhacking.
cl_allowdownload	Allow loading maps, models, sounds, sprites, textures when connecting to the server.
cl_allowupload	Allow your custom spray to be loaded when connected to the server.
cl_anglespeedkey	Determines the ratio of turn speed to +left/+right when walking (+speed). cl_yawspeed * cl_anglespeedkey = turn speed when walking. The default turn rate while walking is 140.7 (210 * 0.67 = 140.7).
cl_backspeed	Sets the speed with the back (+back) key. This is limited to the sv_maxspeed backend. And in CS it’s limited by weapon speed. This must be equal to cl_forward and cl_sidespeed, otherwise you will have problems with simultaneously delaying forward and left, for example.
cl_bob	Sets the amount by which the view wobbles when the player is running.
cl_bobcycle	Sets how often the player’s gaze swings while running. I would recommend leaving this as the default as it messes up your hands after an update (it’s like scaling them). Prior to this update, it messed up your crosshair. Has no effect when cl_bob is 0.
cl_bobup	Sets the amount of time the player bounces while running. Has no effect when cl_bob is 0.
cl_chasedist	It changes how much the camera zooms out while you are dead.
cl_clock reset	If the client’s clock deviates from the server by more than cl_clockreset, we simply reset it to use the server and reset the delta to 0 – this usually happens when the server is logged in and possibly when there is a lot of packet loss.
cl_cmdbackup	Also, with each batch of commands (cl_cmdrate), we resend the last few previous move commands (in case of packet loss) so that we can continue to run smoothly in the face of minor network issues. By default, the number of “backup” commands we send is 2, but you can change this number by setting cl_cmdbackup to a different number. You can send more than 8 backup commands and you should remember that sending backup commands will increase the outgoing bandwidth usage.
cl_cmdrate	This is the maximum number of command packets you send to the server per second. By default, up to 30 command packets per second are sent to the server. If you are running at more than 30 frames per second, there will be multiple commands placed in some packets. You can change the rate at which command packets are sent to the server by setting the cl_cmdrate variable.
cl_corpsestay	Time in seconds before dead bodies disappear from the ground.
cl_crosshair_color	Specifies the color of the crosshair in RGB, the value must be enclosed in double quotes.
cl_crosshair_size	Specifies the size of the crosshair. Possible values are: 0 or automatic / 1 or small / 2 or medium / 3 or large.
cl_crosshair_translucent	Includes a translucent crosshair.
cl_dlmax	Cl_dlmax defines the ” chunk ” size for pieces of player decals, etc. that are loaded during the game. Clamped up to 16 to 1024 bytes. Useful to try and limit decal usage to bandwidth – it made a lot more sense when everyone was using 14.4kbps modems.
cl_download_ingame	Allows you to load custom player sprays during the game.
cl_dynamiccrosshair	Enables dynamic crosshair when crouching/jumping…
cl_fixtimerate	Cl_fixtimerate is the number of ms per frame to fix clock drift . Because the server sends timestamps in every packet, but we only read network information once per frame, we don’t want to just ” take ” the server’s clock, so we use that as a target and ” correct ” it with fixtimerate (if the delta is not will become too large and we will bind the client to the server clock).
cl_fog_b	It sets the value of the blue color of the fog. Fog can be enabled with gl_fog 1. This CVar is hidden by default and you need to add -dev to the game command line for this cvar to work. The only official map with fog is de_inferno_cz. Map authors can add fog to their maps using the env_fog object, which automatically sets this CVar.
cl_fog_density	Sets the fog density. Fog can be enabled with gl_fog 1. This CVar is hidden by default and you need to add -dev to the game command line for this cvar to work. The only official map with fog is de_inferno_cz. Map authors can add fog to their maps using the env_fog object, which automatically sets this CVar. A good value is 0.0003.
cl_fog_g	It sets the green color value of the fog. Fog can be enabled with gl_fog 1. This CVar is hidden by default and you need to add -dev to the game command line for this cvar to work. The only official map with fog is de_inferno_cz. Map authors can add fog to their maps using the env_fog object, which automatically sets this CVar.
cl_fog_r	It sets the value of the red color of the fog. Fog can be enabled with gl_fog 1. This CVar is hidden by default and you need to add -dev to the game command line for this cvar to work. The only official map with fog is de_inferno_cz. Map authors can add fog to their maps using the env_fog object, which automatically sets this CVar.
cl_forwardspeed	Sets the speed using the “forward” key (+forward). This is limited to the sv_maxspeed backend. And in CS it’s limited by weapon speed. It must be equal to cl_backspeed and cl_sidespeed, otherwise you will have problems, for example, holding forward and left at the same time.
cl_gaitestimation	Cl_gaitestimation uses an alternative way to calculate the speed of other players, which is used to control the animation of their lower body (legs). However, cs 1.6 forcefully includes it and the variable is ignored.
cl_gg	If enabled, when viewing a demo with playdemo or viewdemo, it will run the demo in benchmarking mode, exit the game, and save the results in the fps.txt file. This is the same as running the demo with gg “demoname”.
cl_himodels	Includes high quality models. This only works in Half-Life.
cl_idealpitchscale	This was used by a system (mainly for the use of joysticks) to adjust the angle of the eyes when walking up / down inclines. This appears to have been used to ” scale ” how quickly the pitch converged to the ” ideal ” pitch for tilt. This works when lookspring is enabled (must disable browsing with the mouse) and when browsing with the joystick is enabled. The value indicates how many degrees the view changes when walking up/down slopes.
cl_lc	This is called “server-side hit calculation and lag compensation”. This only works if the server allows lag compensation (sv_unlag 1) and if the shooting player requests lag compensation (cl_lc 1 – note that the player must also predict weapon launch on the client side too, otherwise cl_lc is ignored). Don’t change it. See also cl_lw.
cl_logocolor	It defines the color of your spray: #Valve_Blue, #Valve_Brown, #Valve_Dkgray, #Valve_Ltblue, #Valve_Ltgray, #Valve_Green, #Valve_Orange, #Valve_Red, #Valve_Yellow
cl_logofile	It determines which spray you want to use among the following: 8ball1, andre, camp1, chick1, chuckskull, devl1, gun1, lambda, Skull, smiley, splatt, tiki, v_1.
cl_lw	This is called “client-side weapon firing prediction”. This refers to the instantaneous set of effects that occur when the fire button is pressed. All of these effects are performed on the client side if the client side weapon firing prediction is enabled (cl_lw is 1). Effects include: triggering a weapon firing animation, showing any muzzle flash, creating any ejected projectiles, drawing decals and bullets at the hit location on the level wall, triggering the sound of a weapon being fired, etc. However, the actual determination of whether a shot was fired ( at least for weapons with hit scan) to another player now and always has been done on the server. If this is disabled, delay compensation is also disabled. See cl_lc.
cl_minmodels	Enable displaying only minimal models: leet.mdl, gign.mdl and vip.mdl, enabling it may improve performance.
cl_movespeedkey	The speed at which you move when +speed is active.
cl_needinstanced	Enabling this option will display some information about loaded models (weapon models) in the console. You need developer 1 to see the information. And you need sv_instancedbaseline 1 on the server side. (It’s already 1 by default)
cl_nosmooth	It determines whether prediction errors will be smoothly corrected during cl_smoothtime. If set to 1, prediction error smoothing is disabled (same with cl_smootime 0).
cl_observer crosshair	This turns on the crosshairs in the Free Look viewer mode. It’s buggy, it only works if you die and the camera is set to freeview, after changing the spectator mode it won’t work except in the next round if you die and are in freeview again.
cl_pitchdown	Sets the maximum viewing angle to look down. This is locked and cannot be changed in CS.
cl_pitchspeed	This is how fast your up/down loop is with the +lookup/+lookdown commands.
cl_pitchup	Sets the maximum viewing angle to look up. This is locked and cannot be changed in CS.
cl_pmanstats	It displays particle information on your screen. Particles are smoke grenades (maybe there are other things, but I haven’t seen anything else that could change this particle counter). “Number of particles” is the number of particles currently on the map. ” is the number of particles currently displayed on your screen. “CMiniMem Free” is the amount of memory available for smoke.
cl_radartype	Enables an opaque (opaque) radar.
cl_rate	This is the number of bytes per second that the client sends to the server. Note. It’s a command but it works like cvar except sometimes it doesn’t work if you try to set it in your cfg.
cl_resend	The delay, in seconds, before the client resends a connection attempt. This is when you have problems connecting to the server and you see: “Retrying to connect to server #1”. And it has nothing to do with the network code, as people originally did.
cl_righthand	If set to -1, your weapon will be in your left hand and your knife in your right. If it is set to 0, all weapons are in the left hand. If set to 1, all weapons are in the right hand.
cl_shadows	Enable player shadows (small black circle), disable for better performance.
cl_showerror	Show the prediction errors on the screen.
cl_showevents	Enables the display of events such as firing a weapon, all events are listed in cstrike/events/.
cl_showfps	Shows your current FPS in the top left corner of the screen.
cl_showmessages	Drop network traffic to the console. Need a developer to work 1.
cl_shownet	0 Do not display any information. 1 Print the size of the current incoming packet in bytes. 2 Display information about the current incoming packet and its size.
cl_sidespeed	Sets the speed using the left and right movement keys (+moveleft and +moveright). This is limited to the sv_maxspeed backend. And in CS it’s limited by weapon speed. This should be equal to cl_backspeed and cl_forwardspeed, otherwise you will have trouble holding forward and left at the same time, for example.
cl_slist	This is the maximum number of seconds to wait for responses when pinging the LAN ” slist ” . Late responses are ignored.
cl_smoothtime	It specifies the amount of time that the representation will be smoothly correct after a prediction error. If we set cl_smoothtime to 0 (or cl_nosmooth to 1), our interpolation will not be “smoothed” or corrected and we will see the actual positions of the players. Please note that this will cause a jump in the players’ movements, but they will be correct.
cl_solid_players	Whether the motion prediction mechanism should consider other players as solid.
cl_timeout	When you are inactive, after how many seconds the server will disconnect you. This is also controlled by sv_timeout (server side)
cl_updaterate	This is the number of updates per second you are requesting from the server.
cl_upspeed	Sets the speed with the up/down navigation keys (+moveup/+moveleft). This is limited to the sv_maxspeed back end. And in CS it’s limited by weapon speed.
cl_vsmoothing	This is called View Smoothing, and involves interpolation between view vectors. It smoothes/interpolates the origin and viewing angles when riding on trains/platforms. 0.05 should be fine (if you’re above 20fps) and 0 turns it off so it should boost your fps.
cl_waterdist	Compensates for the view along the water surface.
cl_weaponlistfix	This was supposed to fix a bug in the HL1 source code related to the WeaponList custom message – the message would simply be ignored if this was set.
cl_weather	Enables rain on de_aztec, 1 will cause a few drops of rain, 2 will increase their amount, 3 will cause a downpour. Disables it to improve performance.
cl_yawspeed	Specifies the rate of turn with +left and +right.
com_filewarning
prefix	This doesn’t work on Steam, but on Won (pre-Steam system) if you had this CVar set to “0” you couldn’t open the console.
con_color	Sets the color of chat messages. in RGB. In Won (pre-Steam system) it was also used to change the console text color.
con_fastmode
con_notifytime	The amount of time, in seconds, that developer messages remain in the top left corner of the screen before they disappear from the screen.
chicken coop	This was supposed to enable the co-op mode in Quake. This doesn’t work in HL1 because there is NO co-op mod (also doesn’t work in CS because CS is a multiplayer game).
crosshair	Enables the red dot in the center of the awp/scout/g3sg1/sg550 scope.
c_maxdistance	This is the maximum 3rd person camera distance (see cam_command) using +camdistance (cmd).
c_maxpitch	This is the maximum 3rd person camera pitch (see cam_command) when using +cammousemove (cmd).
c_maxyaw	This is the maximum 3rd person camera tilt (see cam_command) when using the +cammousemove (cmd) command.
c_mindistance	This is the minimum 3rd person camera distance (see cam_command) using +camdistance (cmd).
c_minyaw	This is the minimum third person camera deviation (see cam_command) when using +cammousemove (cmd).
fight to the death	It determines whether the server is multi-user (1) or single-user (0). This is automatically set to 1 when you start a listening or dedicated server. It only stays at 0 if you start the map with the “map name” card or play HL single player.
decalfrequency	Sets the frequency at which players can spray their logos. The amount is in seconds, 0 means no delay (spray as fast as possible).
default_fov	Sets the field of view in Half-Life. In CS, the change only takes effect when you zoom out your body in spectator mode after you die. Also, it will ruin your sensitivity if you try to adjust it. In Half-Life, this could be used to get a “zoom” effect even on weapons without a scope.
developer	Enables developer mode. Developer mode can be used to display information on the screen and output extended information to the console. Developer 2 provides more detailed information than developer 1.
dev_overview	It shows an overview map created by the game. Used for cartographers to get an overview image.
direct	Specifies the ambient/direct lighting scaling on studio models.
displays a list of sounds	If set, this shows the list of AI sounds on the console (only with developer 2).
d_mipcap	Sets the maximum quality for all textures, near or far.0 High texture detail.1 Medium texture detail.2 Low texture detail.3 Minimum texture detail.
d_mipscale	It sets the maximum scalable quality of remote textures. 0 Full object detail 1 Some object detail 2 Medium object detail 3 Low object detail And I think you can go to 3.
d_spriteskip	It provides fast rendering of sprites. It will skip rendering every N scan lines.
edge friction	This is used to add slowdown when jumping off the edge. When jumping from a platform that is 70 units above the ground, the edge friction effect is greatly increased. When it is set higher, the force pulling you down is greater. (Gravity in a sense)
ex_interp	ex_interp sets the amount of time (in seconds) to interpolate between each successive update (cl_updaterate). Set this variable to 0 and nothing else. Counter-Strike will automatically set ex_interp to 1/cl_updaterate (i.e. your console will say “ex_interp is forcibly increased to xx ms”). This is because the time between each packet is 1/(number of updates per second), so that’s how long you want your client to interpolate.
feyklag	Simulates a delay when the value is greater than 0. The higher the value, the greater the delay.
false loss	Simulates a cheat when the value is above 0. The higher the value, the bigger the cheat, for this sv_cheats must be enabled.
fastsprites	Determines the quality of smoke puffs, 0 is the worst, 2 is the best. Set a lower quality for better performance.
fps_max	Set the maximum number of frames per second. You can only have more than 100 if developer is 1 (enabled).
fps_modem	This is the old CVar fps_max for the web. Leave this value at 0 and use fps_max.
fs_lazy_precache	Normally, this switch is disabled, which in turn allows the game to load all the necessary sound files for that particular map before launching the game. If this switch is enabled, the game will not preload sound files during map startup, instead, sound files will only be loaded when they are needed. Sound files will remain in memory after they are loaded to improve game performance by not having to reload the same sound files from the hard drive every time a sound file is used.
fs_perf_warnings	Controls whether texture resampling warnings are printed. Requires developer to be 1 (On).
fs_precache_timings	Perf printouts about sound and model loading. Requires developer to be 1 (On).
fs_startup_timings	Manages a bunch of console nonsense about timings when starting the engine. Requires developer to be 1 (On).
gamma	Sets the gamma value.
gl_affinemodels	Applies opengl perspective correction hints: for example: glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
gl_alphamin	This determines how texture filtering with alpha masking (lattices, fences, screen doors) affects the appearance of edges. At higher values, these objects (like bars, fences, etc.) look “thinner”, at a value of 1 they disappear completely.
gl_clear	If you enable gl_clear it will clear the color buffer. This basically means that when the camera can see into the void, either because the card is out of the far clip plane or because of some kind of map data corruption. This is often used as a debugging tool since the color of gl_clear is red. Cartographers use it to see if there are leaks in their maps. Everything seems to turn red in D3D, even if you are not outside the map.
gl_cull	Enables the opengl GL_CULL_FACE setting.
gl_d3dflip	This CVar is only valid in D3D mode. This includes reverse rendering order. With nVidia Detonator 53.03 and gl_d3dflip 0 you can get WH. If you have mouse lag issues in D3D (most of the time in smoke), you can try gl_d3dflip 1, this will reduce the lag or fix it.
gl_dither	16-bit OpenGL rendering can use a form of anti-aliasing in which lack of color depth is hidden by rounding in different ways depending on the pixel being rendered. Setting it to 0 could theoretically be faster or less hideous. Again, this may look more benign. It depends on personal preference. It seems that in 32-bit mode it doesn’t affect the walls, only the sky.
gl_flipmatrix	This is a fix for your crosshair if you are using 3dfx drivers (old graphics cards eg: Voodoo, Voodoo2, Rush or Banshee.) Maybe in CS 1.6 you can’t even use 3dfx servers as there is no option like in 1.5 to enable it . If you use this with other drivers you will get an AWP/Scout scope error.
gl_fog	Turn on/off the fog effect. This was done for CZ, not 1.6, but might work in 1.6. This only works in de_inferno_cz. But with this you can get a color map (or make it work on all maps): you have to have -dev in the launch options and set cl_fog_density to 1 + cl_fog_r/cl_fog_r/cl_fog_g (they control the color).
gl_keeptjunctions	Keep the collinear points added by QCSG/QBSP to fix T-junctions. If you set it to 0 you will see cracks between some of the textures.
gl_lightholes	Controls whether to apply lighting to surfaces with ” holes ” (not sure if this still works).
g_max_size	The maximum size in pixels in which textures are loaded. The value must be a multiple of 16 to prevent white textures from appearing. When a texture is greater than gl_max_size it will be clipped to this size, if this size is not a multiple of 16 it will become a white texture. Although gl_max_size does not have a maximum value, 512 is the most realistic maximum value for gl_max_size.
gl_monolights	Create an even source of light, without shadows. (Also may be referred to as FullBright). When a grenade explodes in an area or you turn on the flashlight, the area’s gamma returns to normal.
gl_nobind	Toggles replacing textures with alphanumeric characters. Deprecated, does not work in 1.6.
gl_nocolors	Do not bind separately colored textures for players. Deprecated and not supported.
g_overbright	Saturated lighting. Makes lighting more natural and realistic.
gl_palette_tex	Enable/disable support for paletted textures. If the GL driver you’re using doesn’t support the extension, it won’t make any difference. But some cards do not support the extension well and support must be disabled using this variable.
gl_picmip	Sets the rendering quality – * higher number is faster but lower quality. Don’t set more than 3 or cs will crash.
gl_playermip	Sets the rendering quality for models. Not supported.
gl_polyoffset	The amount of offset to apply to polygon labels.
gl_reportjunctions	This cvar has no effect.
gl_round_down	This is texture accuracy or texture rounding. When textures need to be changed, they are rounded up or down depending on that. Setting it low SHOULD make textures more accurate, and setting it high SHOULD degrade texture accuracy. I say “MUST” because it may depend on the graphics card. The maximum value MUST be 5, but again this may depend on the graphics card.
gl_spriteblend	He turned on the alpha blending of the sprites. It’s like sprite rendering quality (gl_spriteblend 0 = poor quality), gore and all. (0 = more blood)
gl_wateramp	It enhances water waves (on water maps, of course). This cvar can only be modified with sv_wateramp (on the server side).
gl_wireframe	gl_wireframe 1 does the former by placing glowing lines on each edge drawn by the engine to show how it splits. gl_wireframe 2 does the same, but the lines it creates can be seen through walls, allowing you to tell what part of the map is being drawn (including other areas that might not be drawn!). gl_wireframe 1 is thus good for watching faces break etc. gl_wireframe 2 is best for seeing if your VIS blockers are actually working and stopping other areas from being rendered. This is used by cartographers to see what is calculated to improve the performance of their maps.
g_zmax	Sets the maximum size of zbuffer. This is the maximum visible distance. Setting it to 0 in the D3D renderer allows you to see through walls. Since people were cheating on it, VALVe added protection and now this cvar can only be changed with sv_zmax (on the server side).
gl_ztrick	Half of the Z-buffer range, but not cleared (keeps fill rate). Enabling this setting may cause distant objects to flicker. If you want more frames per second, enable this.
chart height	Sets the height of net_graph.
its sound	Switches high quality sound.
host map	When a map is modified using the “map” command, this parameter is automatically set to the name of the map. For multiplayer, this is only set at server startup, because the first map is started with the “map” command, but when changing maps, “changelevel” is used.
hostname	Sets the server name.
host port	Sets the port to be used for your server. This CVar has the same effect as the “port” CVar, except that if “hostport” is not 0, it is used instead of “port”.
host_framerate	This scales the clock, but only in singleplayer or during demo playback (can be used to fast forward).
host_killtime	Sets the delay before killing the server.
host_profile	Displays the number of connected clients and their network latency.
host_speeds	Displays host FPS, network latency, transfer rate, render rate, and object count for the map.
hpk_maxsize	Specifies the maximum size of the custom.hpk file in your cstrike folder, the custom.hpk file is used to store logos of other players. Its value is specified in megabytes, a value of 0 means no maximum size.
hud_capturemouse	If disabled, there is no mouse cursor in the command menu. This doesn’t work in CS 1.6 and DoD 1.3 because the command menu no longer supports number bindings. But it still works in HL, TFC and some other mods.
hud_centerid	Toggles the display of player names in the lower left corner or in the middle of the screen. The player’s name is displayed when you aim at another player.
hud_classautokill	If enabled, automatically kill yourself after selecting a new player class in TFC.
hud_deathnotice_time	Sets the number of seconds for which death notifications are displayed.
hud_draw	Enables HUD rendering.
hud_drawhistory_time	Sets the number of seconds that the HUD icons are displayed. For example, buy icons.
hud_fastswitch	Toggles quick weapon switching. If enabled, the weapon switches immediately when a number key is pressed (should be bound to slotX commands). This has no effect when you scroll through your weapon (using invprev and invnext).
hud_saytext	It includes in-game chat (same as hud_saytext_internal for CS, CZ and DoD).
hud_saytext_internal	It includes in-game chat. hud_saytext (cmd) toggles this CVar. This is only in CS, CZ and DoD.
hud_saytext_time	Sets the number of seconds that chat messages are displayed.
hud_takesshots	Allows you to take pictures at the end of maps.
people_join_team	This is used for command restrictions. Set to “any” to allow all commands (default), “ct” to allow only counter-terrorists, and “t” to allow only terrorists.
IP	If a connection to the steam server cannot be established, you will need to use this variable on the server’s command line, specifying the server’s ip.
joyadvanced	This allows extended axis variables to be used, starting with joyadvaxisX, where X is the letter of the axis.
joy	Controls the DirectInput R axis mapping (usually joystick-rudder). The following controls can be set: 0 = Axis is not used 1 = Axis is designed to move forward and backward 2 = Axis is designed to look up and down (pitch) 3 = Axis is designed to move side to side 4 = Axis is designed to turn left and right (yaw) ). Alternatively, it can be designated as an absolute axis (such as a joystick) or a relative axis (such as an FPgaming trackball or WingMan Warrior SpinControl). Absolute axes are defined as having a stop position, while relative axes do not have a stop position and just rotate around. To designate this axis as a relative axis, add 16 to the above control number. This will have no effect until joyadvanced is set to 1.0.
joyadvaxis	Controls mapping of the DirectInput U axis (custom axis). The following controls can be set: 0 = Axis is not used 1 = Axis is designed to move forward and backward 2 = Axis is designed to look up and down (pitch) 3 = Axis is designed to move side to side 4 = Axis is designed to turn left and right (yaw) . Alternatively, it can be designated as an absolute axis (such as a joystick) or a relative axis (such as an FPgaming trackball or WingMan Warrior SpinControl). Absolute axes are defined as having a stop position, while relative axes do not have a stop position and just rotate around. To designate this axis as a relative axis, add 16 to the control number above.
joyadwakisw	Controls mapping of the DirectInput V axis (custom axis). The following controls can be set: 0 = Axis is not used 1 = Axis is designed to move forward and backward 2 = Axis is designed to look up and down (pitch) 3 = Axis is designed to move side to side 4 = Axis is designed to turn left and right (yaw) . Alternatively, it can be designated as an absolute axis (such as a joystick) or a relative axis (such as an FPgaming trackball or WingMan Warrior SpinControl). Absolute axes are defined as having a stop position, while relative axes do not have a stop position and just rotate around. To designate this axis as a relative axis, add 16 to the control number above.
joyadvaxix	Controls the display of the DirectInput X axis (usually joystick left and right). The following controls can be set: 0 = Axis not used 1 = Axis for forward and backward movement 2 = Axis for looking up and down (pitch) 3 = Axis for side to side movement 4 = Axis for turning left and right (yaw) In addition, it can be referred to as an absolute axis (such as a joystick) or a relative axis (such as an FPgaming trackball or WingMan Warrior SpinControl). Absolute axes are defined as having a stop position, while relative axes do not have a stop position and just rotate around. To designate this axis as a relative axis, add 16 to the control number above. This will have no effect until joyadvanced is set to 1.0.
JoyAdVaxis	Controls the display of the Y-axis DirectInput (usually joystick forward and backward). The following controls can be set: 0 = Axis is not used 1 = Axis is designed to move forward and backward 2 = Axis is designed to look up and down (pitch) 3 = Axis is designed to move side to side 4 = Axis is designed to turn left and right (yaw) . Alternatively, it can be designated as an absolute axis (such as a joystick) or a relative axis (such as an FPgaming trackball or WingMan Warrior SpinControl). Absolute axes are defined as having a stop position, while relative axes do not have a stop position and just rotate around. To designate this axis as a relative axis, add 16 to the control number above. This will have no effect until joyadvanced is set to 1.0.
joyadvaxis	Controls the mapping of the Z-axis DirectInput (usually a throttle stick). The following controls can be set: 0 = Axis is not used 1 = Axis is designed to move forward and backward 2 = Axis is designed to look up and down (pitch) 3 = Axis is designed to move side to side 4 = Axis is designed to turn left and right (yaw) ). Alternatively, it can be designated as an absolute axis (such as a joystick) or a relative axis (such as an FPgaming trackball or WingMan Warrior SpinControl). Absolute axes are defined as having a stop position, while relative axes do not have a stop position and just rotate around. To designate this axis as a relative axis, add 16 to the control number above. This will have no effect until joyadvanced is set to 1.0.

joy yawsensitivity	Controls the speed or ratio used when you look from left to right.
threshold of joy	Controls the dead zone for looking left and right.
Lambert	Sets the Lambert level. Lambert is lighting the player models.
light range	Sets the game lighting gamma. It has a security that should be forced to 2.5 when connecting to a server, but it looks like a “broken” security because the gamma is set before the security is set, so you can still change that before connecting to the server. When a grenade explodes in an area or you turn on the flashlight, the area’s gamma returns to normal. If it is changed, it may crash the game. Paft Edit: Actually yes, 0 used to be the lowest value and now the game crashes, but 1.9 is the new low.
download as 8 bit	Toggles the use of the lowest quality 8-bit audio. On = 8 bits. Off = 16 bits.
logsdir	Specifies the directory where server logs will be created using the “log” command.
lookspring	Enables automatic view centering when mouse browsing is disabled (-mlook). It must be set when mouse browsing is enabled (+mlook). It also disables up and down mouse movements.
glancestrafe	When this feature is enabled, left/right mouse movements cause you to move sideways instead of turning.

mp_chattime	The amount of time in seconds that players can chat after the game ends.
mp_consistency	This checks to see if the connecting client has changed its models or sounds to give it an unfair advantage. For some models, it only checks the size to make sure it doesn’t exceed the hitboxes. But this doesn’t check all models/sounds/… Some of them are still there, like the smoke sprite. (not to smoke)
mp_decals	It sets the maximum number of decals (splash, logo, bullet holes, grenade burns, blood on the ground) to be visible on the screen. It must be installed before connecting to the server. This is not the same as r_decals.
mp_defaultteam	If set to 1, players are forced to join the first team (team index 0) when joining. Otherwise, they are forced to join the team with the fewest players. If a map forces them to join the first team (mp_defaultteam 1), then players are not allowed to change teams during that map (unless the map changes their team for them). This is one of the properties of the map, so the map will automatically set the cvar value depending on what the mapper has chosen.
mp_fadetoblack	If set to 1, the player’s screen turns black until the end of the round when they die (the screen still works fine so the player can chat, see results, etc.) Overrides mp_forcechasecam
mp_falldamage	Enables realistic fall damage in Half-Life.
mp_flashlight	Set to 1 to enable the use of flashlights, 0 to disable.
mp_footsteps	Set to 1 to enable steps, 0 to disable.
mp_forcecamera	This cvar was added in CS 1.4 and seems to be exactly the same as mp_forcechasecam. If mp_forcecamera and mp_forcechasecam are set to a value other than 0, mp_forcecamera will be ignored and the value of mp_forcechasecam will be used instead. teammates only (Free Look works)
mp_forcechasecam	It looks like this variable is exactly the same as mp_forcechasecam. If mp_forcecamera and mp_forcechasecam are set to a value other than 0, mp_forcecamera will be ignored and the value of mp_forcechasecam will be used instead. teammates only (Free Look works)
mp_forcerespawn	If enabled, players will automatically respawn upon death.
mp_fraglimit	If set to a value other than 0, when someone’s result reaches mp_fraglimit , the server changes the map.
mp_fragsleft	mp_fragsleft is the number of frags left if you set mp_fraglimit. You just type mp_fragsleft into the server console and it will tell you the number of frags left depending on the mp_fraglimit. NOTE: mp_fraglimit does not exist in CS and only seems to work in Half-Life.
mp_freezetime	The duration in seconds of the freeze period at the start of the rounds. Set to 0 to disable.
mp_friendlyfire	Set to 1 to enable friendly fire, 0 to disable.
mp_ghost frequency	Ghost update period. How many seconds are left until the next update. In cs beta 5.0 you could see freeview spectators move when you were dead (they were called ghosts). But the ghosts were removed after. This cvar now has no effect.
mp_hostagepenalty	Maximum. the number of hostages you can kill before the server boots you… setting this to 0 will disable this command.
mp_kickpercent	Sets the percentage of teammates it takes to vote for a player.
mp_limitteams	The maximum number of players one team can have over another. To completely disable command restriction, set the value to 0.
mp_logdetail	Bit variable to set the level of detail for logging attacks “mp_logdetail 0” » Log no attacks “mp_logdetail 1” » Log attacks from enemies “mp_logdetail 2” » Log attacks from teammates “mp_logdetail 3” » Log attacks from enemies AND teammates
mp_logecho	If enabled, server log messages are displayed in the server console.
mp_logfile	Enables server console logging to a file in the logs/ folder.
mp_logmessages	Used for server admins to spit chat messages into their log files.
mp_mapvoteratio	Set the ratio of players required to vote on the same map before the map changes. The default value is 0.66, which means that 66% of the players on the server must vote for the same map in order for the server to switch to that map.
mp_maxrounds	Leave the maximum number of rounds that can be played on the map at 0 to match mp_timelimit.
mp_mirrordamage	This CVar has no effect. It’s been in CS since the first betas. It’s not even in the CS specific cvar part of the CS Manual. This will probably be a feature where when you attack teammates it reflects damage back to you and they don’t take damage. The original creators of CS probably didn’t finish the code or forgot about it.
mp_playerid	Toggles the information players see on the status bar 0 all: players see all names listed on the status bar (with their respective team colors) 1 team only: players only see the names of their teammates and hostages on the status bar 2 off: players don’t see any names in the status bar status bar (including hostages)
mp_roundtime	Minimum round time 1 min. The maximum round time is 9 minutes. Supports partial minutes (1.5 – 90 seconds).
mp_startmoney	Sets the amount of money players start the game with.
mp_teamlist	This determines the names of the commands in HLDM depending on the models. Nothing to put, allow all commands. List of valid team names: barney, genie, gman, gordon, helmet, xgrant, scout, robot, scientist, zombie.
mp_teamoverride	Allows maps to override server mp_teamlist.
mp_timeleft	mp_timeleft is the amount of time left before changing the map if you set mp_timelimit. You just type mp_timeleft into the server console and it will tell you the amount of time left based on the mp_timelimit. NOTE: mp_timeleft only works in Half-Life. This is useless in CS due to the “timeleft” client console command which does the same thing.
mp_timelimit	Period between card rotations.
mp_tkpunish	If set to 1, TKers will be automatically killed on the next round.
mp_weaponstay	This causes the weapon to immediately respawn after one player has picked it up, allowing the next player to be able to grab the weapon immediately.
mp_windifference	It is used by the CS to determine the difference between the T and CT payoffs to apply the win logic.
mp_winlimit	Will loop the map after one team reaches this number of wins.
m_filter	Toggles the mouse filter. The mouse filter smooths out mouse movements.
m_forward	It determines how fast you move forward/back when you move your mouse. In order to move forward/backwards with the mouse, you need to turn off browsing with the mouse.
m_pitch	Sets the sensitivity ratio of mouse movements up and down. Negative numbers cause inverted mouse movements. This cannot be changed except in the options menu with “Reverted Mouse” which sets m_pitch to -0.022.
m_side	It determines how fast you move when you move your mouse. Requires lookstrafe 1 and Mouse Look Enabled (+mlook) to navigate with the mouse.
m_yaw	Sets the sensitivity ratio between left and right mouse movements. Negative numbers cause inverted mouse movements.

pause	Allow or prevent players from pausing the game using the pause command.
port	Sets the port to be used for your server.
indicator	This is the number of bytes per second that the server sends to the client. Only for internet games (sv_lan 0), except when sv_lan_rate < 1001 in LAN game (sv_lan 1).
rcon_address	This allows clients to remotely connect to a server/HLTV and use rcon commands without even being in the game. Set it to the server’s IP address without a port number (1.2.3.4).
RCON password	It sets the rcon password on the server so admins can use admin commands/variables. Administrators must also set rcon_password in their client console to be able to use admin commands/options with the rcon command.
rcon_port	The port through which the client can remotely connect to the server. See rcon_address.
type of number	Cartographers use this to create an echo on their map, this automatically changes when a player enters a zone with the env_sound entity. Various values: 0 = Normal (off)1 = General2 = Metallic Small3 = Metallic Medium4 = Metallic Large5 = Tunnel Small6 = Tunnel Medium7 = Tunnel Large8 = Camera Small9 = Camera Medium 10 = Camera Large11 = Bright Small12 = Bright Medium13 = Bright Large14 = Water 115 = Water 216 = Water 317 = Concrete Small18 = Concrete Medium19 = Concrete Large 20 = Large 121 = Large 222 = Large 323 = Cave Small24 = Cave Medium25 = Cave Large26 = Freak 127 = Freak 228 = Freak 3

r_bmodelhighfrac
r_bmodelinterp	Determines whether moving brush models will interpolate their position (smooth the view).
r_cachestudio	Determines whether to cache studio model ” hulls ” for faster testing – the cache has a limited size/lifetime. This is a performance optimization.
r_cullsequencebox	In a multiplayer game, if set, instead of just checking the bbox on the back of the viewer, we check the entire truncated pyramid for the current animation extents (sequence window).
r_decals	It sets the limit for decals (logo spatter, bullet holes, grenade burns, blood on the ground). If higher than mp_decals, mp_decals will be set (reset to mp_decals when connecting to server). This is not the same as mp_decals.
r_detailtextures	Enable/disable detailed textures. In cs 1.6, by default, there are detailed textures only for Cobble.
r_drawentities	Controls how objects/models are drawn. 0 = No objects 1 = Default and draw objects normally 2 = Objects are drawn as skeletons 3 = Objects are drawn, each bone has a bounding box 4 = Objects are drawn with a block 5 = Separate blocks for player and weapon NOTE: only works in SOFTWARE – D3D/OpenGL mode: single player only SoftWare: multiplayer mode
r_drawflat	In “r_drawflat 1” we see how the engine has to break up surfaces in order to draw them. I think it’s being used by cartographers.
r_draworder	WallHack, which shows what is computed through walls, is used by cartographers to improve map performance.
r_drawviewmodel	Switch weapon model view.
r_dspeeds	0 = Do not display renderer speed statistics. 1 = Display renderer speed statistics. (Developer 1 required)
r_dynamic	Dynamic lighting is when illuminated objects create projections onto walls or objects around them (example: rockets in half-life). You will improve performance by turning this off. But after the HL update, it is locked to 1 in multiplayer.
r_fullright	Setting this to “1” means no lightmaps, and will render all textures without any dynamic shading/lighting (so you’ll end up with brightly lit textures, so bright that even a flashlight beam will be invisible). Setting it to “2” will mean lightmaps only (all models gouraud shading without textures). NOTE. THE SPECIFIC VALUES ARE NOT FOR OPENGL, ONLY FOR PROGRAM MODE. Okay, this might be useful for cartographers. A setting of “3” means only lightmaps, but with an offset mesh. Setting to “4” is similar to “3”, but also shows the mip level of each surface in relation to the player.
r_glowshellfreq	Sets the glow frequency of player models. Player models are highlighted by server plugins. For example, respawn protection in deathmatch.
r_graphheight	Adjusts the height of the chart. See r_timegraph
r_lightmap	I only get the effect with this variable in D3D and Software: D3D: r_lightmap -1 or 1 = White walls.
r_lightstyle	r_lightstyle 1 removes all lights on maps, but you can still see enemies and the sky.
r_luminance	r_luminance 1 makes the whole map blue-green.
r_maxedges	This variable sets the maximum number of flat surface edges to render.
r_maxsurfs	This variable sets the maximum number of flat surfaces to render.
r_mirroralpha	Mirror effect. Deprecated and not supported.
r_mmx	This includes MMX optimization. MMX is detected automatically (1=enabled, 0=disabled), but you can force it on or off with this.
r_norefresh	Disables world and HUD updates.
r_novis	First you need to know what VIS is: VIS is short for Visible Information Set. This generates what can and cannot be seen from certain locations on the map. Half-Life will then use this information when the game starts to speed up rendering by only drawing what the player can see. you can see everything. You can try with gl_wireframe 2 to see the effect.
r_numedges	Shows the number of edges displayed at one time.
r_numsurfs	Shows the number of brush planes displayed at one time.
r_polymodelstats	Displays the number of polygon models shown

r_timegraph	Toggles the display of a graph showing the screen rendering time. It’s like net_graph, but for FPS only.
r_traceglow	Enables occlusion calculation. If enabled, light halos (created by the env_glow entity) and some explosion sprites will not be visible through AI players (hostages in CS, scientists and monsters in HL) when they are behind them.
r_wadtextures	r_wadtextures is used to enable or disable enabled wad textures.
r_wateralpha	r_wateralpha 1 enables alpha water blending (default). To disable it (0), r_novis must be enabled. Turning it off will allow you to see above the water everything below the surface of the water (which effectively makes the surface of the water completely transparent). This does not work with the Half-Life 1 engine. To get transparent water, mappers must use the func_water entity.
r_waterwarp	If 0, then there is no underwater wave effect. Use 0 for better visibility in the water.
scr_centertime	The time in seconds that the messages on the central screen remain active. (Example: the message “The terrorists won!”). Note that this only works if set before the message is printed, not while it is being displayed on the screen.
scr_connectmsg	This is the first line of a small message in white text drawn on a black box at the bottom center of the screen. It is usually only visible when connected to servers, as everything is rendered on top of it. Also visible with r_norefresh 1 or when clipping outside the map. Depending on your hand model, when disconnected from a server, it may only be partially visible when connected to another.
scr_connectmsg1	The second line of the Connect-Message window. See scr_connectmsg.
scr_connectmsg2	The third line of the Connect-Message window. See scr_connectmsg.
scr_conspeed	It sets the speed at which the console comes into view when the player presses the console key. This no longer works in version 1.6 because the console no longer appears in view.

snd_noextraupdate	If enabled, disables “excessive” audio updates that may occur during rendering or other potentially low frame rate situations.
spec_autodirector	This enables the Auto Director viewer mode. Auto Director automatically moves the camera based on where the player is looking. This works for Free Chase Cam, Locked Chase Cam and Chase Map Overview. (Same as spec_autodirector_internal for CS, CZ and DoD).
spec_autodirector_internal	This enables the Auto Director viewer mode. Auto Director automatically moves the camera based on where the player is looking. This works for Free Chase Cam, Locked Chase Cam and Chase Map Overview. spec_autodirector (cmd) toggles this CVar. This is only in CS, CZ and DoD.
spec_drawcone	Toggles the 90-degree orange vision cone in view mode, which shows where you are looking in spec mode (same as spec_drawcone_internal for CS, CZ, and DoD).
spec_drawcone_internal	Toggles the 90-degree orange cone of view in view mode, which shows where you are looking in spec mode. spec_drawcone (cmd) toggles this CVar. This is only in CS, CZ and DoD.
spec_drawnames	Toggles drawing names in overview mode (same as spec_drawnames_internal for CS, CZ and DoD).
spec_drawnames_internal	Toggles drawing names in overview mode. spec_drawnames (cmd) toggles this CVar. This is only in CS, CZ and DoD.
spec_drawstatus	Toggles the game information (current map, game time, …) that is displayed in the upper right corner of the screen in spectator mode (similar to spec_drawstatus_internal for CS, CZ and DoD).
spec_drawstatus_internal	Toggles the game information (current map, game time, etc.) that is displayed in the upper right corner of the screen in spectator mode. It’s only CS, CZ and DoD and it doesn’t work in those games anymore since Steam.
spec_mode_internal	Changing this while playing has no effect. You must change it before entering the server. It sets the first observer mode you have when you enter observer mode (when you are dead or an observer). This is automatically changed when you change spectator mode using the JUMP key, the spec menu, or the spec_mode command. in emergency situations and the Czech Republic.
spec_pip	Sets the PIP spectator mode. 0 : Disabled 1 : Player Chase Camera 2 : First Person 3 : Chase Map View (zoomed out) 4 : Chase Map View (zoomed in) 5 : Buggy Mode (you see cone sprite view + player sprite view like in the map view, but works in third person, etc…)
spec_scoreboard	Turns on/off the scoreboard. “togglescores” (command) toggles this CVar. This is a CVar specification, but you don’t have to be a spectator to use it. This is only in CS, CZ and DoD.
suit volume	Sets the volume of the HEV suit sounds in Half-Life.
sv_accelerate	Sets the acceleration speed. Locked (only in CS), so it automatically switches to the default value (5). But in HL you can change it and the default value is 10.
sv_aim	Enables auto-aim (when your crosshair is close to an enemy). Only works in Half-Life.
sv_airaccelerate	It sets how fast you accelerate in the air. Use 100 for surf cards.
sv_airmove
sv_allowdownload	Allows the server to upload any content to the client (maps, sprays, etc.)
sv_allowupload	Allows clients to send custom sprays to the server.
sv_alltalk	Allow dead players to communicate via voice chat with live players. Also allow players to communicate with the opposing team/spectators.
sv_bounce	Controls the collision response of ” flying ” projectiles when they hit slopes.
sv_cheats	This command allows you to use cheat codes such as impulse 101 (16000 money) or impulse 102 (blood). All variables in the “cheat” category in the variable list only work if enabled.
sv_clienttrace	sv_clienttrace sets the player’s bounding box for collisions (with world objects). This is not the same as setting the hitbox size (used for bullet hits). This cannot be changed in CS, it is forced to 1. The value may differ from other HL mods. (3.5 is used in DoD etc.)
sv_clipmode
sv_contact	It is used to set the server owner email.
sv_downloadurl	Installing this CVAR will allow clients to load custom content via HTTP rather than fetching content from the game server much faster. Set this parameter to “” (an empty string) to return to normal downloads.
sv_enableoldqueries	Setting “sv_enableoldqueries” to 1 allows old-style (no request/response) queries to work (this allows you to use the old HL1 Engine core query protocol). This should be disabled now because webserver browsers etc are using new requests to the server.
sv_filetransfer compression	Allows the server to compress and send compressed content to the client.
sv_filterban	Sets packet filtering by IP mode. If disabled, everyone will be banned by IP, but their IP will not be added to the banlist.
sv_friction	It controls the friction against the ground. This is locked to 4 in CS and cannot be changed.
sv_gravity	Sets gravity. A smaller value means less gravity. You stay in the air with sv_gravity 0 and cannot jump with sv_gravity 12000. Negative values have the same effect as sv_gravity 0 but jump much faster.
sv_instancedbaseline	Allows the server to create and use “instance” baselines (for things like grenades, etc. that don’t have good baselines because they’re not placed in the .map file).
sv_lan	It includes LAN server mode (no heartbeat, no authentication, class C). Only people on your local network can join.
sv_lan_rate	It defines the rate for all clients on the LAN server (sv_lan 1), default is 20000. If sv_lan_rate < 1001 it will be ignored and “rate” (client side) will be used.
sv_logbans	It turns on and off the registration of player bans. Default is 0 (off).
sv_logblocks	This is part of the rate-limiting code for out-of-band requests (i.e. players, information). It logs which IP addresses have been blocked by this code. See also max_queries_* variables.
sv_log_onefile	It determines whether one log file is created (in total) or one log file per map change, as is currently the case. The default is the current behavior (one for each map change).
sv_log_singleplayer	If enabled, log files will be generated for single player games. Of course, logging (login) must be enabled.
sv_maxrate	This sets the maximum number of bytes per second that the server can send to the client. 0 = unlimited. Only for internet games (sv_lan 0), except when sv_lan_rate < 1001 in LAN game (sv_lan 1).
sv_maxspeed	Sets the maximum speed. In CS, after 260, nothing changes because of the speed of the weapon (With a scout, you go faster, and this is 260). See the forum for more information.
sv_maxunlag	Sets the maximum number of seconds during which the netcode compensates for someone’s ping (sv_unlag must be enabled). Netcode offsets 500ms by default.
sv_maxupdaterate	This is the maximum number of updates per second the server can send to the client (see cl_updaterate).
sv_maxvelocity	It sets the maximum speed of any moving object.
sv_minrate	This sets the minimum number of bytes per second that the server can send to the client. 0 = unlimited. Only for internet games (sv_lan 0), except when sv_lan_rate < 1001 in LAN game (sv_lan 1).
sv_minupdaterate	This is the minimum number of updates per second the server can send to the client (see cl_updaterate).
sv_newunit	Used to clear saved game data from previous levels to keep the saved game size as small as possible. This is used in the Half-Life single player maps. There is no need to change this CVar, mappers should set it in the worldspawn object.
sv_password	Sets the password for the server. People who want to connect to the server need a password.
sv_proxy	This is necessary so that HLTV proxies can connect to your server. It sets how many HLTV proxies will be able to connect to your server. HLTV proxies take up server slots so make sure you take that into account before enabling this.
sv_rcon_banpenalty	The number of minutes to block users who are not authenticated by rcon. (0=permanent)
sv_rcon_maxfailures	The maximum number of times a user can fail rcon authentication before being banned. This is similar to sv_rcon_minfailures, except that this setting is independent of sv_rcon_minfailuretime.
sv_rcon_minfailures	The number of times a user can fail rcon authentication within sv_rcon_minfailuretime before being banned.
sv_rcon_minfailuretime	The amount of time (in seconds) that rcon attempts must fail before the ban is enforced.
sv_region	This is for the server browser filters to specify which region the server should appear in.

sv_stop speed	It sets the minimum stop speed on the ground. In Half-Life and other mods the default value is 100. But in CS it is locked to 75, if you change it it will always go back to 75.
sv_timeout	Controls how long the server will disconnect a client that has stopped responding (it might just be AFK).
sv_unlag	This allows clients to use lag compensation. Leave it enabled.
sv_unlagsamples	Sets the number of packets that will be averaged to find a ping to compensate (sv_unlag must be enabled). Examples: sv_unlagsamples 1 The server will calculate the ping from the last sample. (default) sv_unlagsamples 2 The server will calculate the ping from the average of the last two samples.
sv_uploadmax	It limits the maximum size (in MB) that a customer can use for a custom resource (such as spray stickers).
sv_version	The default is 1.1.2.0/2.0.0.0.47.3647. This is some information about the server version. These are the numbers that appear when you type “version”. For example, here: 1.1.2.0/2.0.0.0 is the game version/mod version. But we all know that CS version is 1.6, but it shows 1.1.2.5/2.0.0.0. In other mods it also shows 1.1.2.5/2.0.0.0 or 1.1.2.0/2.0.0.0 except CZ where 1.0.0.2/2.0.0.0.47 is the protocol version. 3647 is the build version.

sv_voiceenable	It includes voice communication.
sv_voicequality	If your server has voice enabled, you can set the voice quality here. Keep in mind that the better the quality, the more bandwidth your voice will need. The voice_speex codec must be enabled (see sv_voicecodec). high quality
sv_wateraccelerate
sv_wateramp	It enhances water waves (on water maps, of course). This cvar automatically sets gl_wateramp (same but on the client side) on all clients.
sv_waterfriction
sv_zmax	Sets the size of the Z-buffer. This is the maximum visible distance. Mappers can set the desired value on their map (with the world spawning entity) and it will automatically change that cvar when the map is loaded. It changes the gl_zmax value of any client that connects to the server. VALVe added this variable because with gl_zmax 0 you could see through walls (in the D3D renderer), so the client is forced to use the server’s value and cannot change gl_zmax. This can only be used in multiplayer on dedicated servers (only works in single player on listening servers).
sys_ticrate	This command sets the maximum number of ” frames ” per second that the server can calculate.
s_a3d	Turn on A3D sound technology. Your sound card must support it.

tracing speed	This sets the speed of the tracers. Tracers only work in HL with 9mm weapons, as well as some other mods. There are no tracers in CS.
vgui_emulatemouse	This causes a mouse cursor to be emulated (this can be useful for older graphics cards that display a flickering mouse cursor or no mouse cursor at all).
vid_d3d	It was like switching between OpenGL and D3D modes, but since it requires restarting the game, it doesn’t work. OpenGL is set to 0 and D3D is set to 1. It automatically resets to the video mode you’re in when you join the server.

Set this to 0 if you want to play sounds using HLSS/HLDJ, as this makes the music fade out and become muted after the song is played continuously.
voice_forcemicrecord	He sets the recorder to Wave Out Mix instead of Line 1/Mic. The HL engine tries to make sure that the mixer control settings are set correctly while playing, but not all sound cards work the same, especially very high end ones. sound cards such as Audigy 2ZS pro cards. If you’re having issues with the microphone not working after launching the game, try setting this setting to 0.
voice_inputfromfile	If set to 1 and you use +voicerecord this will not record your voice but will play the WAV file from your cstrike/voice_input.wav.
voice_loopback	When you turn it on and speak into your microphone, it will loop your own voice so you can hear your voice.
voice_recordtofile	Records your voice to a file if set to 1 and you speak into the microphone. Two files: voice_decompressed.wav (does not contain actual audio) and voice_micdata.wav (you speak).
