Basic Console Commands
Now.. this area will just be console items you can input to make your FPS rise a little.
Items will be listed Command 1/0 . 1/0 means you can toggle it on and off using 1 or 0 respectively.
r_3dsky 1/0 - Turns off the clouds and sky effects. SOME FPS is gained, not a lot though.
r_shadows 1/0 - As far as I know, all it changes is being able to use flashlights. It might disable shadows though.
r_dynamic 1/0 - I believe it disables dynamic water effects... not quite sure. Disable if you don't like the water or there is alot of water and it lags you.
r_lod 1/0 - Not sure...supposedly helps FPS (Supposedly it changes the 'level of detail' but to no effect.)
This is all I know so far, but they seem to help.
Now for some cheats:
NOTE:You have to enable SV_cheats to use them.
sv_cheats 1/0 (1 to enable cheats, otherwise they don't work)
God - Simple eh? God mode. Invincible.
Buddha - Takes away damage or something..
Noclip - Back from the Quake 1 days... you can fly basically, through walls, floors, doors so forth.
Notarget - Enemies don't know your there, some triggers still happen though, like Antlions popping up or enemies/allies spawning at parts of the map.
Impulse 101 - All weapons, full ammo.
Impulse 102 - Spawns a human skull that just pops out of the sky..
Impulse 82 - Spawns buggy. Fun!
Impulse 83 - Spawns Air-Boat.
cl_drawhud 1/0 - turns hud display on/off
