With everything on full, its running at about 40fps on my rig (2500k @ 4.7Ghz / 7970 Windforce 1100/1500 / 8Gig 1600Mhz Ram / 180GB Vertex 2) I havnt got any more time to test with lower settings to see if you can get it at a constant 60+
When I say everything on full, I mean everything on full including 8x AA!
