Did you try moving the cards around, probably separating
the distance between your Verite and Flash?

The difference in performance, or lack of, that you see
would be due to the heavy amount of "to the metal"
programming that went into the Verite version.  Carmack's
finger file mentioned having to extensively deal with
the Verite's RISC core - not a happy thing.  As for a
possible Voodoo "to the metal" port, here's an interesting
excerpt from someone creating an optimized OpenGL driver
for the Voodoo and the expected performance increases:

How about Moto Racer?

Didn't you try 3DFX's latest Descent2 patch?  It
supposedly eliminates the slowdown you mention.
