I think this issue stems from CryEngine. I read somewhere on the forums about it, a Crytek Rep posted to turn of DX11 Features and use DX9 and you should not have any problems. Just have to wait for a newer version of CryEngine or revert to the older version for the problem to be fixed.
indeed forcing to dx9 mode works pretty well ( no crashes )
i guess the sdk is pretty bad optimized for AMD drivers
