I've just installed the game and I'm having some significant graphic issues. When I play the game in fullscreen, the screen is flickering constantly, while its fine when played in windowed mode. I've messed around with the ingame settings. It works perfectly with all maxed settings in windowed but still flickers with lowest in fullscreen.
Graphics Card: ATI Radeon HD 5950
Processor: Intel i& Quad Core overclock to 4ghz.
