Didn't see anything so good that I'd like to see on the screenshots. Pretty much the same shit.
And yes, I'm on XP but I have DX10 GPU. I'm not going to upgrade to Vista/7, I'm all good with DX9. Actually pretty relieved that the DX10 is Vista+ only (apart from some DX10 only games, like upcoming Alan Wake), I can play with DX9 and kep graphics settings pretty high, I'd probably have to take them down a bit with DX10.
