I went ahead and tested a few combinations of Super Sampling Anti Aliasing and the new FXAA from Nvidia that came with the latest drivers. I'm using Dolphin 2.
No AA:
2.25x SSAA + FXAA:
2.25x SSAA:
FXAA:
The combination of 2.25x SSAA + FXAA is the one that gives the best improvement in quality. But note that the latest Dolphin doesn't have the option for 2.25x SSAA, it only has 4x and 9x.
As a side note, I use Dolphin 2 to play Brawl instead of the latest Dolphin because no matter what I do, I can never get the latest dolphin to run as fast as Dolphin 2 in Brawl.
