Maybe this will help, first you should remove current driver, remember to remove everything include Profiles.
- Then install driver from the CD comes along with your Card
- Create new profile with suitable AA, AF setting
- Run the game several times to check whether the game runs properly with AA,AF on.
- If it's ok, you now can update your driver with new software from vendor's website.
This is the way I fixed my problem with AA, AF.
