TemporalAntiAliasing(MotionBlur)on Voodoo4 4500PCI

[Gemail]

For all I knew by now, this special T-Buffer effect that is the Temporal Anti-Aliasing, also named as Motion Blur should not be able to perform on a Voodoo 4 4500 PCI. I saw on various documentations that the only T-Buffer effect Voodoo 4 is capable of displaying is the Full Scene Anti-Aliasing 2x (FSAA2x), as this boards are single chip solutions. On the other hand, Voodoo 5's, as they are double or quad chip boards are able to do not only FSAA 4x/8x, but also TAA (Motion Blur).
To my big surprise, playing the game MotoGP2 with my Voodoo 4 4500 PCI (PC verssion, 1xVSA100 @166Mhz, 32Mb SDRAM) - courthesy by Rolo01, this special effect popped-out:

It looks like Motion Blur to me, the game's readme clearely states that this special effect will be displayed on video cards that support it, but how is it possible for a single chip Voodoo 4 to do Temporal Anti-Aliasing?

..you need to put " around your hyperlink (like this "http://img305.imageshack.us/my.php?image=motionblur9rk.jpg")

I doubt this type of mblur uses 3dfx t-buffer..

Why should motogp2 use this T-Buffer which is 3dfx vsa only feature? You know those effects can be easily done in software.

I have this game and its done in software, a radeon or geforce card does exactly the same thing, so it's not a T-Buffer effect

with glide64 (glide3x pluging for n64 emus) u can get this awesome motion blur effect in zelda's majora mask:

If the effect is done in software, why can't the game emulate it when using a Voodoo 3? It would be much fun!

[r21vo]

Because it might be too hard to make it work on Voodoo3, because it has less features/memory.
