Playing at 1280X1024 in vista dx10 with hardware in sig with all settings on very high brings my system to its knees. Averaging 20-30fps with 15 in heavy fights. WOW thought my system would do better than this. Kinda disappointed. Graphics are sweet but not that sweet. The sunlight glistening through the trees is pretty impressive. Game play is well thought out. Enemy's have pretty good AI, circling around you and calling for help. Physics are really cool, shooting down trees, driving through sheds and so on. All in all I'll prolly buy it.
