I installed win 10 yesterday upgrading a win 7 and after a few problems now its working fine with some exceptions.
The mos t important problem that I have is that when im playing and for example a friend calls me from skype I minimise the game and its all slow. It takes me like 30 seconds to just press the answer button. Dont even try to open chrome or another app .... its slow like a snail. All recovers when I exit the game though.

Any sugestions?
