Hi,

I have two mismatched Voodoo2 12MB cards (Gainward Dragon 3000 and InnoVision Mighty 3DII) that I am trying to make work in my Win98SE build along with a GeForce Ti4200 on an ASUS P3B-F, the idea being to have a powerful D3D card for everything non-Glide with a great DOS compatibility, and the Voodoo2 SLI for Glide. When I try to run Glide stuff in Windows it freezes the computer when using some drivers - particularly FastVoodoo2 that I want to use to be able to have SLI with mismatched cards...

- I am testing using the demos provided with FastVoodoo2 4.6, but I also tried with games (GLQuake, Quake2, Unreal Gold) and the results are consistent
- Problem happens with official 3DFX drivers 3.02.02 (latest ones), FastVoodoo2 4.0 GE and 4.6
- Problem does NOT happen when using official drivers 3.03.00 and 3.03.00b (both older than 3.02.02...weird numbering scheme)
- The problem is not only with the Ti4200, I tried a MX440 and a TNT2 with exactly the same results. Tried with a Savage4, and everything works fine with all 3DFX drivers...
- I was initially testing under Win98SE USP3, DX9.0c and Nvidia ForceWare 81.98, then reinstalled a bare-ass Win98SE. Straight after the OS install, I only change the drivers for the Voodoo2 card, leaving the main card with "Standard VGA Driver" and install absolutely nothing else - the behavior is exactly the same.

Are there known incompatibilities I am not aware of? Any solution?

Thanks as usual!

There are no compatibility issues that I know of. Voodoo II doesn't use the 2D card for anything.

The only thing I can think off at the moment is this: FastVoodoo drivers automatically overclocks the cards to 96Mhz (no idea why). This can persist after driver uninstall. Try to downclock the cards to 90 or even 88 Mhz and see if that helps.

You might also want to pull out the cards and test them one at a time.

Thanks, should have mentioned ruling out a SLI problem was my first step and the exact same behavior happens with a single card (I didn't try both of them though, I focused on the InnoVision as the Gainward has shitty blurry output). Still exactly the same problem. I also tried to downclock the card to factory default with FV4.6, same result.

I want to emphasize the problem doesn't only happen with FastVoodoo though, latest official 3.02.02 gives exactly the same results, while 3.03.00 and 3.03.00b work...which leads me to think official 3.02.02, FV4.0 Gold and FV4.6 must be doing something in common that make the P3B-F shit the bed when using a more advanced Nvidia AGP card.

When I find some time today I will try the Gainward alone to confirm it does the same too.

I also use the savage4 with v2sli (matched pair) and it works well. I do wonder if the mismatch is the underlying issue though ...

Thank you, unfortunately it is not a SLI issue, happens with a single card as well. And the Savage4 is the only card I've thrown at it that works as expected with all drivers, while TNT2, MX440 and Ti4200 have the issue.
