Okay so i played it flawlessly last night for about 3 hours straight but when i come home today and try to play i get a full blue screen on the main menu, so i find that by disabling motion blur, it temporarily fixes this problem. but now i notice another problem. every single time i move my mouse the game freezes for a second and then returns to normal.... but if i use the arrow keys, the game flows through the menu like butter. anyone else have this problem?
