This was happening a few days ago and i upgraded my 670 driver and it went away. i logged into wow today and me resolution was messed up along with this discoloration so i reset the settings and now my res is fine but when using lying mounts im getting a cloudiness around the wings. i had my gpu oc'ed so i went to stock settigns and its still doing this. is something wrong with my card? any ideas? its kind of hard to see in pics
