Very low frame rates with Sapphire 9100

I just upgraded (?) from a GeForce2 MX400 (Asus V7100DC) to a Sapphire 9100.

The FPS with the nVidia was 65, now, with the 9100 they are 16! This was running Preformance Test V4 at the 1024x767x16 85Hz setting max. textures (same test on both cards).

Epox 8RDA
2x 256 Crucial PC2700
Win 2k w/sp3
nForce2 V2.03 UDP
Catalist V3.1 (also tried V 7.83 from Sapphire which I think is the same thing)

Everything stock, no overclocking. This is on a fresh install of 2k

I read that changing between modern ATi and Nvidia Vidcards sometimes requires a wipe 'n reinstall of the OS.

More than a few folks say that a format followed by a fresh OS installation is needed with WinXP. But--I don't know if this holds true for Win2K.

It also was a fresh install.
DX Diag looked good.

It just seems to be the 3d tests that are slow.
I did all the other tests and they are fine.

The test I'm using is Preformance Test V4 from Passmark:

http://www.passmark.com/index.html

It seems to be a issue with the "Wireframe Mode" test. This card doesn't support that function/aspect.

Here is a response from the author of the program regarding the problem that should be of interest to anyone with a ATI card:

"There are lots of cards that either have no hardware acceleration for 3D or
only limited acceleration. Although to be fair it is mostly the older cards
that have poor 3D support. There is a vast array of 3D functions and most
cards just support a sub-set in hardware. In general, the newer the card the
bigger the sub-set.
Our experience with ATI support was very poor. Even when we were sure we had
found bugs in their drivers they didn't answer ours E-mail. Good luck."

If I uncheck the "Wireframe Mode" under advanced/3D graphics, the frame rate goes from 16 to 220FPS at 1024x768x16 at 85Hz!

I wonder how important "Wireframe Mode" really is? Are your BM's under Futuremark, erstwhile Mad Onion's 3DMark2003 OK? Remembering that an ATi 9700 Vidcard is the only one that gets a decent score?

How about 3DMark2002?

I'm running Mad Onion now.
Probably not that important, but it is a nice small program that gives you meanful FPS as oppose to semi-meaningless benchmark scores.

I think that there were not any 3dmark02, just 3dmark99, 3dmark2000, and 3dmark01, and the latest 3dmark03.
