AA will continue to be in effect for the remainder of that game. You will, however, have to repeat the resolution change for each new game you start/load. If you are playing a season, for example, and play two games back to back, you will have to change the resolution after the coin toss for each game to gain AA. Edit: I should also note that I began reporting this issue to ATI with the 3.9 Cats. The same behavior can also be seen with the "3.85" leak based Omegas.
