same thing here, game freezes in dx11
i have a gtx470, win7 x64, i7 930 cpu, 6gb ram
when the game freezes the game mouse cursor turns into the windows white mouse cursor, but only in a small box area in the center of the game screen. weird. I was able to play a game for about 30 mins, but the crash happens every time now upon loading the game after about 5 turns.
have not tried dx9 yet
