Installed these drivers and was going through my gaming profiles setting up various aa enhance options that I use and noticed that if you have sli you can now select SLI32xQAA !!

Anyway selected 32xAA and got a warning about this would disable sli performance to increase image quality. When I went back to 16xAA which is what I normally try to use if possibe a warning popped up saying that visual quality would be decreased by enabling sli performance mode. Just what is SLI performance mode ?


Incidentally I played through about an hour of HL2 with 32xQAA and it stayed between 47 and 60fps with vsync on. Using that program DXTweaker to get tripple buffering to work correctly with vsync so the framerate doesn't halve when it drops below 60fps. Also tried with vsync off and the tearing was not as bad as I remember with previous drivers. Framerate was over 200fps most of the time :D Of course I know with newer games 4xAA might be a struggle.
 
The above posters are talking about two different AA modes.

OP, is talking about the 'so called' sli anti-aliasing, where sli mode is disabled and one card is used purely to anti-alias the image.

Poster beneath him is talking about 2x supersamping anti-aliasing with 8x multisampling.

I have never managed to get sli anti-aliasing working correctly, I don't think it works as a per application setting correctly.

2xS+8MS however looks lovely and is a nice manageable replacement for 4xS (which uses far far too much video ram).

Excuse me if some of that comes across badly, it's 2am, sleepy.
 
I wish they would release 32xAA for single 8800 cards, its not like the 8800's could not do it especially since 16xAA does not lower performance much at all in some games.
