I am not sure if it is the same problem that I am experiencing also. I experienced problems after updating with the patch 1.50 to 1.55. When playing warfare multiplayer after about 10 minutes of game play my screen goes completely black. I can still hear what is happening but not see anything. I have ctrl, alt del to quit and try again.
