A way to remove/limit smoke particles?

Every time a smoke grenade, frag grenade, or any kind of explosion next to me happens, it rapes my framerate HARD. I was wondering if there was a way to limit and less preferably remove the smoke particle system?


Then what’s the point of a smoke grenade?

Very good point, but I wish to limit the particles it emits, but make them bigger. Not remove them, but if removing them is what it takes, then so be it.
