com_maxfps x (x = fps cap) for Quake/Doom engine games
I dunno abt other games... anyone else have any more?
Yea, I think capped fps does make things seem smoother... still though, it is more important to make sure that your minimum fps is higher than anything else....
the less change you have in your framerate the more you will perceive it as being smoother, consistency is just as important as making sure your min fps doesn't bottom out
