This is the first game to really challenge my system. With an FX57 and 7800gtx sli I thought I'd be safe to turn everything on. I was wrong! Soft shadows are out of the question, and they look horrible anyway. Although the game is pretty playable at 1600x1200 with 2xAA, I've now turned the AA off to get a steady framerate in the most taxing areas. I was getting lockups when volumetric lighting was on screen until I switched to the latest beta drivers.
