I'll try that, thanks for the help though :>
I don't see why this problem even happens when I'm able to play Crysis 2 smoothly :/

I never found a solution I'm afraid. The problem dissappered when I got amy new Nividia GPU. The best I could do before that was turning down the resolution and disableing some graphics features (sun shafts and anti-aliasing). Sorry that I couldn't be of more help :(

I added you so that you can help me with my Red Faction Gurrilla. If you found a solution can you please help? I saw your forum and no one there has said anything that has took away the flickering and sun glare.
