I'd say 30fps but correct me if I'm wrong.
I play PC, runs and looks great on my 2 year old rig @ 1080p. Though of course, buy a controller if you buy it for PC! Xbox 360 Controller for Windows can be had at a decent price fairly commonly.
And yes, for some reason the -1 and -2 speeds aren't present in the PC version (weird that). BUT, the PC version gets the fantastic modding community! Apart from that, the gameplay is identical.
