I had two screen freezes on DX11 and two on DX9. It took a three finger saute to get me a white screen then a pc power down to get out of that. All in GVs. None in the air.
After the fourth one, I went back to the default graphics setting after having success with previous patch pushing the video card to the limit. Had no freezes after that but may not have had enough game time to be sure of that.
Fingers crossed.
