Having a very frustrating issue whereby when I tab out of Word of Warcraft instead of instantly going to Windows I get a 4 second pause a green line flash accross the screen and then the same again when I tab back in. Having checked various forums I have seen talk of AMD card not supporting directx 11.2. Could this be the issue? If so when will it be fixed. Also people talking about variations in setting between windows and WoW, again could this be it? I think I have both at max settings.
Any help greatly apreciated.
