Is there a console command or anything to turn on Volumetric lighting in multiplayer, I MISS IT !!!!!!!!!
You mean the volumetric shadows? Hmm, sort of. You can't get the same nice shadows, but you can get ones that are almost as good.
Just type \cg_shadows 3 in the console. You'll notice the shadows are darker and kind of buggy. I keep it on normal, because they both look ugly.
