I finished the second version of my FSAA demo with hardware acceleration, Cuincunx AA, filters, LOD bias. If you are interested, you can download it from:

FSAA demo 2

Be warned that it may not work on your config. It was succesfully tested on TNTs, Geforces, a Radeon and a G400 but the Kyro and Savage2000 refused to run it. I did not test other cards. It requires DX8.

It appears to run fine on my Voodoo5500. Out of curiosity what sort of figures should I be getting?

Although the speed of the demo is indicative of the speed of the actual methods, it is not exact. Eg. I cannot simulate multisampling with conventional hardware so the performance hit of Cuincunx AA is exaggerated. So the speed is not too important, but the image quality is.
Fps 0n my Geforce256 DDR, using 32 bits and 0 LOD bias, cube size maxed out, 800x600 desktop res (for testing only):

no AA: 920 fps (700 anisotropic)
2 smps: 512
4 smps: 271
9 smps: 125
16 smps: 71
2 smps Cuincunx: 309
4 smps Cuincunx: 175

The demo does not use the inherent FSAA capabilities of the cards, it forces simulation. So the only thing that determines sim. speed is actual fillrate. Tiling architectures does not have an advantage in this case because there is no overdraw.
