I run the game as administrator and UAC is disabeled. No change. I tired to do something with compatibility option, it only worseen the situation.
I have noticed that the configuration tool semms to have no influence on the game : I have always the intro video, even if i have not tick the "play intro video" option.
One more thing : my loading screen is made only from text, the picture with it doesn't appear, but the intro video plays well.
