Hi ) My problem is in changing windows in game: When I hit Alt+Tab, colours turns mad, game moves to the top of the screen and doubles. Minor problem in freezes in game, its annoying. From time to time my computer totally freeze and returns to normal in 3-4 minutes. I tryed all cofigures in settings, nothing helps. Config: Intel i3-2350M 2.3 GHz Video Nvidia GeForce 410M Win 10 x64 You are my last hope
