Hi graphics guys...

i went to an empty multiplayer server, and tried changing these cvars from 1 to 4 to see if there are any visual differences and FPS differences:
so far i found these 4 without any visible effects... any idea what do they affect?

sys_spec_particles (no visible difference from 1 to 4)
sys_spec_volumetriceffects (no visible difference from 1 to 4)
sys_spec_physics (no visible difference from 1 to 4)
sys_spec_textures (no visible difference from 1 to 4)

if they don't really add to visual gameplay, i might as well set them to 1

Maybe you need to restart the game,

Try putting it in your cfg files

I'm sure sys_spec_texture is updated live on singleplayer, without restarting the game, but I knew multiplayer had shrunk graphics so that everyone can achieve more FPS.
Anyway if 1-4 doesn't affect FPS, you might aswell set to 4 =P

makes sense...
