Yup!
I'm pretty sure it only happens in dx11 though.
My game also completely freezes generally when I first log on after about 3-5 minutes. Many times just after I take off. My game will completely freeze. I have to control alt delete and close out the game that way. When I try to come back in, I get a white screen for about 2 minutes and then finally the game comes back on to the first start menu. Still have no Idea what the heck is causing that but its really aggravating.
