I downloaded the new ATI goodies that are supposed to fix this issue but I still have them. Any time I see a spot of light my screen just starts to flicker. Did I not fix this issue correctly or has it not really been resolved? I got the new 1.2 patch with Crysis as well but it's still unplayable.

Any help would be greatly appreciated.

1. did you download the right ATI update? there were 2 for steam versions and ones that weren't on steam
2. turn off vertical sync with multi gpu enabled
3. if nothing works, continue playing in windowed mode, that is a temporary solution to the problem

Im an idiot. I must not have rebooted after installing all the updates. It works fine.
