30 FPS is acceptable, 60 would be good, 120 is ideal for action games but thoroughly unnecessary in menus and turn based stuff. And it's nice to know that my computer can run the game with out breaking a sweat or having to slow down at any point...
But 950+ FPS is so many times any monitors refresh rate or any living creatures flicker rate that it leaves me scrathing my head and wondering 'why?'.
I'm not saying we should cap the frame-rate, just that ... I'm really not sure what I'm saying other then anything faster then 10 million trillion frames per picosecond is overkill.
What exactly are we updating every time the sun emits a new photon anyway?
