I just wonder why it is that v1 and voodoo rush are having trouble with fast systems, even though the pci bus is running at a normal 33mhz.

My guess that the game/driver/other software component has to wait until something (texture upload?) has finished and the wait is simply not long enough on a fast enough CPU.

I went into more detail about this in another thread; it's most likely bits rolling over. it would be the same thing as the buffer overflow bug in the MT-32, or close to it.

How would you compare it to a Voodoo 1 or 2? I've never owned one so I can't make a comparison.

I'm planning on exploring this in more detail. But on a V1 for example, even at 1024 x 768 the desktop is very blurry. In games there is also a difference. But as always, if you don't have them side by side it is hard to see what could be improved. But the V3 clearly has a better image.

VB\V3 is sharp.
Clearer then NV cards until you reach the FX line, which from what I remember, has parts of the 2d tech took from the 3dfx remnants that NV acquired.

You can add to the broken games list Alien vs Predator Gold edition - same problem with textures....

V2's broken AVP is due to a regression in the DX7 beta+ video drivers. Using the earlier DX6 v2 driver (even when you have DX7 or newer installed) won't have this issue

Thx Phil, that is EXACTLY my problem, BUT it depends on the programm.
Some D3D Games do not make glitches with a P3-600, others look like this.
OpenGL/Glide is fine though.

I do not know, what the real difference is.

Please test these two D3D Tests. One is fine the other produces the texture glitches. (with the latest 3dfx-v1-ref-driver)

What's the point in comparing a Voodoo1 against a Voodoo2 in a system that is completely off for a Voodoo1..?

It's not that thing about comparison, it about that issue with the v1 in faster systems.
In my case it's only a D3D problem and it depends on the game, so it's possible fixable.

Doc

It is! It's clear from the beginning that a Voodoo1 has no chance in a system powered by a Pentium II 400 or faster. A much slower CPU already has enough power for software T&L to hit the Voodo1's limit. If at all, such a test should rather find the sweet spot for a Voodoo1 by starting with a fast 486 and then testing with faster CPUs unless the one is found which no longer gains more fps.

I can only put a v1 in that case!!!! I cannot get my hands on a canopus voodoo2 that is short enough.
I cannot downgrade the cpu either!!!! the lowest supported cpu is a cel-533.
So I have to stick to the voodoo1 and the onbaord i815e and both are VERY good.

I did some more investigating and I am now sure that it is the 8-bit palletized textures in D3D!!!!
If this can be fixed the voodoo1 will be fine in my P3-600.
