@Hz133: update your drivers to the latest available at nvidia.com and try again.
I understand there is some kind of problem here bug have no way to replicate it. Are you guys able to provide any other details you can? Have you tried (DirectX) using the Autoplay mode? the editor? different maps? turning off snaking?All works in window mode. But i can't play in fullscreen mode using DirectX. Maybe it's only on my PC only.
