For some strange reason the game freezes if I use it in 64bit mode. This problem is came with DX11 version. It freeze when I hit ESC on track or if I use Alt+Tab. I tried to use the game in Win7 compatible mode, I reinstalled the game, deleted all the 3rd party plugins, reinstalled Win 10 and didn't help. Is there any official answer for this problem? Because since DX11 came out the game is a pain to play.
