Flickering/flashing 'shadows' with AA enabled

[sillyeagle]

Why does this game produce horrible flashing 'shadows' with AA enabled? Not sure if they are actually shadows, but they are transparent black sections wcih flicker and flash in behind trees and vegitation. Had the same issue on WinXP and win7, on 8800GTX and GTX260, and with all driver revisions. Surely somebody else has seen this too. Any solution?

never seen it before myself. odd that it happens on both of your video cards. maybe erase the shader cache files and let the game recreate them?
