So now that I have Dead Space 2 I want to enable some quality AA on it, I followed this thread instructions http://forums.guru3d.com/showthread.php?t=338040 which are really helpful buy I cant find the "Compatibility" option everyone seems to have. I tried using the magnifying icon and I only get the "Unknown" and "Undefined" options. I ran the program as administrator and still no progress. Any help would be appreciated. It happens with every game, not Dead Space 2 only. By the way I have the latest 270.61 drivers , I use a gtx 260.
