Just curious why you need AF enabled? Skuzzy has posted more than once it doesnt work well with AH, or at best does nothing for you in the game. At worst it can cause problems. I've tried it both ways and honestly cant find a real difference, except every so often I get lockups with AF enabled. If you feel you need it so badly, the Nvidia control panel lets you setup a profile for different games. Set up one for AH with your AF disabled, and it will only be disabled when you run AH. Simple.
