I am getting exactly the same, set it to disable crossfire and I also enabled the 'crossfire' status for the top right of the screen so that you can see if your cards are running together, launch the game, no crossfire status but the game runs like sh!t, after manually disabling crossfire its fine on one card
Even after todays update of Ghosts its no better and sometimes feels worse tbh
