Yes you're right as far as I'm aware.  3dfx FSAA is through the T-Buffer, wheras the Geforce equivalent was 'AA' and was based in the driver software.

As to the Voodoo4 4500 AGP I'm afraid I have to agree that this is a substandard card, and will never outperform even a Voodoo 5 5000 PCI.  Of course if someone has any evidence to the contrary I'd be definately interested to see it... Wink

Actually, the Voodoo 5 5500PCI is only marginally slower than it's AGP counterpart...2-3% I believe...

so would it be possible to create 4x anti ailsing through software for the V4? I don't own one, I'm just curious. It would be a lot of work to do if it can be done, but is it possible?

Yea very true indeed my friend. Wink

3dfx worked quite a 'flanker' on the consumer with the 5500 AGP. :p

The FSAA is done by the VSA100 by jittering (the grid - of course  Grin), but has little to do with T-Buffer! You can get T-Buffer on Voodoo3 also! Yet no FSAA!  Sad

Heck, that was one helluva confusing thing in the VSA100 documentation!  Grin

Anyhow, no VSA chip was multisampler! Multisampling looks nice for interior of a polygon, but is not good for intersecting polygons!

Well, that's from my memory! I have a friend who's FSAA filter encyclopaedia  Grin I _COULD_ scratch my docs about supersampling vs multisampling, though...
