Enhancing application fsaa settings..

[Gerard]

Usually something i don't bother with as i normally just stick to ingame settings. Was going to try 32x for a laugh but it seems the control panel wants to disable multigpu mode to do this:

Wonder why it would want to do this as performance on a single gpu would be pretty bad to say the least. Or is it disabling one gpu from game performance to handle the anti aliasing setting?

Think Rroff would know.

The 200 series doesn't natively support 32x AA - it needs to use both cards to do 32x AA (simple, not entirely correct, explanation: effectively doing 16x coverage on each GPU - the max supported - and then combinging the output) you don't get the same performance hit as doing 32x AA on one GPU but it won't give the greatest performance either.

I think I heard it uses the second GPU for the AA via CUDA or something.

I seen a review a while back showing 64xaa available on a 295 sli setup, apparently done via a registry entry.

Try Nvidia inspector, it offers AA modes I never knew exsited.

AFAIK proper 64x AA is only available on the 200 series with Quad SLI but I could be wrong.

tri-SLI 400 series cards can do 96x AA lol.
