@ferelxyx:

put the game as administrator, it has helped some people.
I also think it works better (for me) if I disable windows aero before loading the game

It seems that a lot of people are having this problem,
it is supposed to be fixed with the game patch

anyway update the game and the graphics drivers

regards

Hello

Let's see if anyone else has something to contribute
