View Full Version : AA/AF Force in Driver or application?
03-25-05, 07:07 PM
Hi, i'm trying to find the best balance of AA/AF levels in my games. Ive realized that I don't totally know the answer to this question and I was wondering if someone could help.
Generally is there a performance difference between enabling AA/AF settings in the driver vs the application (game)?
For example: In World of Warcraft there is an Anisotropic Filtering slider that can be set.
Should I set the slider to the value I want in the app and set the driver to application preference, or should i set the driver to the value and leave the application alone?
Thanks so much,

Use AA/AF app if theres AA/AF option in the game you would like to play & force them via the control panel if the game dosent have option for them in its own settings . thats what i would recommend .
the difference between app for force is minimal to none .
so far i only noticed 1 case where forcing AA got me better performance than in-game . the game is Painkiller : BooH in ATi drivers . but thats not common really .

For all ATI cards I've owned, it's always been better to force AA/AF via the control panel regardless of the game. On NVIDIA cards, it's better to force it in-game. I've never been sure why that is, but that's always the way it's worked out in my experience.

Thats exactly the answer I was looking for. Very helpful!

Create a profile for the game in question and specify the settings you want in there. There is a utility called nHancer that makes profiles much more straightforward.
Forcing things globally in the control panel is just old fashioned and nasty nowadays.

My experience is the same as saturnotaku's. Forcing is best for Ati, Application is best for Nvidia.

Here's three examples of AA in HL2....
No AA = pic (http://img72.exs.cx/img72/696/noaa3fq.jpg)
4AA, in-game = pic (http://img72.exs.cx/img72/5305/4aaingame2iu.jpg)
4AA, via Drivers = pic (http://img72.exs.cx/img72/4033/4aadrivers9zb.jpg)
as you can see, appling AA through the drivers doesn't work anywhere near as good as appling the AA in-game, there's not much diffference between 'no AA' and '4AA via Drivers'
