Hey!

I already searched the Forum but could not find a solution for my problem. All I found was something with green darknes and shadows...
However, this is not my problem.

When I am not moving in the game, the issue is not visible but as soon as I start walking I have the whole display flashing green every few seconds.

The error does not occur in other games but is also affecting the steam overlay.

Anybody to help me?

I am using a Radeon HD7850 on Windows 7 x64. I am not overclocking.

Thanks,

Regards.

EDIT: I didn't have the issue just after I installed the game yesterday.
