Only noticed it in those two games so far (Bulletstorm and Bioshock, do they use the same gfx engine maybe?), anyone any idea what the problem is? Thought it might be nvidia's fault but the steam guy has an ati card and win xp.

specs for what its worth, win7, i5, gtx570, 4gb ram.

Not sure but installing the game latest updates/patches and video drivers might solve the problem.
