When i enter the game, it loads and the framerate is pretty good. But the graphics in small portions disappear, and come back very fast when i move. its only in certain spots on the screen. it only does it with this game, and i am using the latest drivers 5.4 catalyst. could it just be the demo? or is it my hardware?
