It doesn't mean Frames Per minuteS. In fact FPS = Hz really.
I honestly am glad when I see my (rather heavily powered) PC getting up to 75 Hz and my laptop up to 60 Hz. And those are the maximums I can reach when scheduling Warzone as *high* priority and returning immediately from SDL_framerateDelay. (Those are the same I can reach with the original implementation as well btw.) -- Giel
