Thanks, but on that page, Fallout 3 already appears to be using alpha-AA by default for ATI cards when AA is being used, unlike with Nvidia cards.
Even Nvidia's best TR-SSAA mode does not clearly show the tree above the building in the lower right corner (the tree is almost non-existent), while all of ATI's modes show that tree so conspicuously and anti-aliased.
Also, you seem to base your conclusion on only one game, Half Life 2 Episode 2, in that since there was not a difference between ATI's Performance and Quality Adaptive AA, Nvidia's TR-MSAA is roughly equal to ATI's Quality Ad-AA. After closely looking at Nvidia's TR-MSAA, I see so many sampling errors on the fence that it is almost worse than leaving them with jaggies. It certainly seems that ATI's Ad-AA is at least equal to Nvidia's TR-SSAA, not TR-MSAA.
