The installer screwed with my computer more than the actual game did, which was a surprise. It did run, at absolute lowest settings, without slowdown that I could detect. The graphics did glitch on me a couple of times, one of which (switching view mode in the little Hummer wannabe caused it) was a show-stopper and required toggling back to the menu and the original view to get out of.
Not sure of the FPS since I was busy playing the game; it's surprisingly difficult, and I have some nasty things to say about the weapon accuracy. Firing aimed three-round bursts you can't hit a man-sized target at under 30 yards half the time, which is totally unacceptable. The only good thing to be said is that the baddies are equally inaccurate...except their machineguns, which seem to be much less accurate in your hands (and I noticed don't overheat when an enemy is firing them!).
And even when you do hit them, a lot of the time they take six or seven hits to go down, or more. I repeatedly nailed people in the head with a short burst at 10-15 yards or so and they kept fighting through it. I've dropped enemies with single rounds too, but those hit as far as I can tell in the high chest or neck.
