I have read that there is a lot of other gamers there have the same problem so I hope that crytek will come with a new patch or at least some news about that they know and they are working on something there can fix it.
My rig is
I7 950 3.2 ghz
6gb 1750mhz ram
Gtx 580
3 wd green 500gb in raid 0
If some of you know soothing about what I can do to play the game in dx 11 again I will be very happy.
