Late on the reply but whatever, I hate people that don't know what they're talking about. MSI Afterburner is probably the number one program any PC gamer would want on his computer. It can: Overclock your GPU, control your GPU fan(s), take screenshots, capture videos, display FPS/GPU Temps/GPU Usage and bunch of other things while in game and as I said, cap the FPS in any game.
Its an awesome piece of software. Yes, he could use com_maxfps, but that only works for Call of doodles.
