Je recherche toutes les commandes consoles pouvant servir pour une lan : écran noir, etc.
Je recherche aussi toutes les commandes qui ont une influence sur la rapidité du jeu : apparition des grenades, textures, ou même 'rate' par rapport au serveur.
Le fichier fourni sur le site server.counter-strike.net (cs console commands) est insuffisant et incomplet.

Commands  
 
Counter-Strike, like most other mods, has some special commands and variables.. Let's run them down!
 
Client Commands:
To use a command, just type '[NAME]' (except with the the vote-functions). All of them just do the listen function.
 
buy
Opens the buy menu to purchase various weapons, items, and ammo.
 
Voting Systems
To vote for a map type listmaps at the console to see the maps available to vote on, and then type 'votemap X'. Replace X with the corresponding number of the map. Note: Server admins who want to add new maps must also add an entry into mapcycle.txt, this allows players to vote on any new maps. The percentage is defined by mp_mapvoteratio, a server variable. It defaults at 60%.
 
To votekick a player type listplayers in the console and then type 'vote X'. Replace X with the number of the player. You need 61% of the team or server vote for a player to be kicked.
 
adjust_crosshair
Changes the color of the crosshair. You can choose from several different colors.
 
gunsmoke
Typing this command will either turn on or turn off smoke coming from your own weapon.
 
timeleft
Tells you how much time is left on the map
 
drawradar
Shows the radar
 
hideradar
Hides the radar.
 
nightvision
Bind this key to toggle NVG when purchased.
 
alias
Not a CS specific command either, using this command in your autoexec.cfg will also you yo store various commands under one command names. For example: alias [ALIASNAME] "[COMMAND]; [COMMAND]; [COMMAND]; ...". The three periods denote that the commands can continue, ';...' are not a command to end aliases. Now if you bind [ALIASNAME] to a key or type it in the console, all the commands will execute.
 
menuselect X
Not so much a CS command, this Half-Life command will select an item from the menu (eg buy; menuselect 1; menuselect 4 will buy the p228 pistol).. Used with quickbuy aliases.
 
Client Variables:
These are used to change certain aspects, or options, or Counter-Strike.. They can also change performance. To change their values, simply type '[NAME] [VALUE]' at the console.

hud_centerid X
X = 1 to center auto-ID text on screen, X = 0 to have auto-ID text in the bottom left corner (default 0).
 
rate X
This command controls how much information you receive from the server you are connected to. For a 14.4 connection set your rate to 1500, a 33.6k connection should be 3000, a 56k 3500, an ISDN should be 5000, and all connections faster than that should be between 5000 and 9999 (default 2500).
 
Tweak Half-Life <http://www.tweak3d.net/tweak/halflife/>

dm X
X = 1 to display map briefings after loading new levels, X = 0 to disable (default 1).
