fps_max 25 it limits your fps to 25
r_lod 8 the models quality looks like a crap
mat_picmip 4 the texture looks blurry
r_shadows 1 this disable the shaddows
muzzleflash_light 0 this disable muzzle flash light every time you shoot
r_dynamic 0
r_dynamiclighting 0
r_maxdlights 0 this disable all lighting but maybe it looks kinda dark so you can also add mat_fullbright 1
