whats the command to....

you know when you shoot any kind of ki blast through a tunnel or something and you see the light coming off of the blast shine on the wall? i wanna turn that off to help my game run faster. wondering if there was a command for it....

cl_fxquality "1"

but I don't think it disables the light from beams, I'm not 100% sure though.

nothing, i was able to change that option from options menu anyways...also im using steam if that helps...or not..
