Something is wacky with FS mode. every time I run the game its FS mode on the monitor but also window mode on my other monitor I have to windows key+ desktop to get to my desktop because the - min button on the windowed monitor doesn't do any thing. once I get the window min then the full screen works and I can then alt-tab to other programs.

I never had this problem with the dx9 ver. also I think because of this problem it's cutting my FPS way down. with dx9 I would get 140FPS on max settings with lowest FPS dipping into 50's.

now with DX11 my FPS with most settings at normal and AA set to 8x I still get crap FPS high of 49FPS low of 30FPS. I have a AMD 7970

but to the OP I had the problem too.
