Flickering Problem

[gonyoda]

Hello All! I looked around on the forums and found some other users with this same problem, and the problem seemed to be fixed for them, but I tried those things and it didn't work.

When I start penumbra or amnesia, the game flickers. Nothing else seems wrong, it just flickers.

CPU:
Windows 7 Ultimate 64-bit
Intel Core2 CPU T7200 @ 2.00GHz (intel centrino duo)
3072MB RAM
ATI Mobility Radeon X1400 - 1405MB

Any idea why this is happening? I've tried turning on/off Vsync and other settings nothing seems to work...help!!!
thanks!
