Alright, I ran it fully playable on Win98SE, Voodoo5 5500 ;D

I used 3D Analyzer V1.52, and have it launch the Game.
No Options of 3D Analyzer were selected though, as they appeared not needed.

What still won't work correctly :

- Detail Textures - Enable

This actually works, but it seems Objects having Detail Textures are turning plain white when viewed from a Distance.
There's also a visible Area ahead of the Detail Textures, so it looks a bit like really bad Mip-Mapping that way.

- Projectors - Enable

That leaves some Texture/Clipping errors around some Objects, although (in principle) it does work... Although I have no exact Idea what it does ;)

Errors still present :
I had minimal amounts of Texture errors remaining (occasional white lines/spots inbetween textures), but that's a real minor thingy.
The only "big" thing still not working is the Sky in DM-Oblivion? (that open sky DM Map), which is discolored and looks a bit ugly...

But all in all, it DOES work.

Driver used for this one :
x3dfx V1.07.00 3rd party Driver.

Since it's mostly 3D Analyzer, that (somehow) corrects most of the errors all by itself, I don't think the Driver matters too much...

Hmmm...

This is a bit weird, but I now can also Play the Demo without 3D Analyzer...

Looks like some internal Game settings are getting straightened out by it, and now everything is (mostly) fine...
