That's impossible, because in some games it's enabled and you can't turn it off, and it causes weird things.
For example: Planetside. Anis. Filt. does weird things to texture LODs, for some reason you get high res textures up close but really low textures far away.
Reguardless if it's a driver issue or a game issue, the cause of it is what I'd like to be able to disable.
Application preference turns it off for the card. It will only use AA then if the game has an option for it or has it enabled. You will need to find a way in the game to turn it off if it is giving you trouble.
