I personally use AmigaMerlin 2.5 SE for the V3 in WinXP. To me it is very stable and offers great performance.
Can you please check under WinXP with said driver while giving a go at 3Dmark 2000?
I find this setup to be a fastest and easy way to find if a card is faulty or not. Let us know... 😀

Im using windows 98 but I think I can do that. Give me a few and I'll report back.

I was unable to find the driver you suggested for win98 but I am using AmigaMerlin 2.5. I started up 3dmark2000 and it said it cant run the default test in 1024x768. I actually can't change the resolution in windows at all from 640x480 which I thought was strange.... So I ran the benchmark in 640x480. Other then that I didnt really notice any thing and it finished running the benchmark.

recording of the benchmark running

edit: i figured out why i couldnt changes resolutions. if you think i should re run the test in 1024x768 let me know. I dunno where I got that 2.5 driver but installed the 2.9 version and it runs more or less the same as far as I can tell.

Hi, this the link to the Driver I use:
https://www.3dfxzone.it/download/?object=3dfx&objid=392

Make sure to Uninstall the old and reboot after installing the new, after that reboot again.

I don't see no artifacts, but the benchmark score is very low (~400).

I get around 2300-2500 with a Duron 700 or with a Celeron 800, and about 2800 with a Pentium 3 1000. What Cpu do you have?
Also the framerate is higher in 1027x768

Try it and let me know 😀

i listed my specs in the first post. I'm not sure I can use this driver because I use windows 98. I only seem to get the artifacts at low resolutions like 320x200 in DOS.

Sorry, I cannot assist you any further because my knowledge is limited. I personally consider the V3 a 3D card meant for late 90's games, not Dos. Also the MMX (166?) isn't suited for a V3, I think it is best paired with a Faster Cpu (600-1400mhz-ish)...
From the Video you posted I didn't notice any artifacts, I would consider the card to be working, but this is just my opinion.
Ideally you need to check the card in another slightly faster system 😀

whether or not a voodoo 3 is appropriate for an mmx 233 machine is irrelevant. theres no way this can be considered working. At least not properly. Ive used 2 gpu's made AFTER the voodoo 3 that don't do this.

found the solution. other people had the same problem. i should have searched around more first.

Issue with Voodoo 3 at 320x200
3DFX Voodoo 3 3000 - Inconsistencies with some DOS and Windows Games

"This is indeed an issue tied with Frame Buffer Posted Write. On slower systems like the K6-2/3 this option hampers performance when disabled (under Windows mostly). The issue usually disappears as soon as SVGA modes are used and I've encountered it in multiple games such as Doom, Duke Nukem 3D and Terra Nova.

If there's no BIOS option for it, I'm not sure what else you could do to fix this issue "

I fixed it on my machine by disabling "VGA Frame Buffer" under Chipset Features Setup

Interesting, I am experiencing the same issue with my Voodoo 3 2000 (AGP version) but unfortunately, my BIOS doesn't have that option. My motherboard is Abit KT7A in case anyone knows a different solution for it.

I've also tried using MTRRLFBE, as suggested in one of the linked threads, but none of the settings solved the artifacts problem. The only thing that seems to help is using SETMUL to disable L1 cache on my CPU. In that case, the artifacts disappear but my system becomes too slow to run late DOS games like Duke 3D.

if you dig around a little in those links I posted there might be some other solutions. See if your mobo has Frame Buffer Posted Write under chispet features setup if you haven't already. Good luck fixing it man.

this is from one of those threads I linked:

Maybe some software like TweakBIOS would allow to tweak those options?

TweakBIOS did allow me to change the options and it worked correctly. Everything is now in working order. And there was only a 1-5 FPS impact in some games, so all is well now.

I'm not familiar with tweakbios so i guess use it at your own risk if you decide to go that route. good luck man. https://www.majorgeeks.com/files/details/tweakbios.html

I tried turning off various BIOS settings that seemed related to the graphics card, but no dice so far.

Unfortunately, TweakBIOS doesn't appear to support the Via KT133A chipset that my motherboard is based on.

Does anyone know of a third party utility that can turn off Frame Buffer Posted Write? Even a windows based program would be fine.
