Hmm...
News Update :
- the Card works under Win2k now
- seems there were 2 Connectors (bent) around a Voltage Regulator on the Card, that went unnoticed by me and interfered with each other
Working drivers :
- x3dfx Win2k V1.07.00 and V1.07.00beta
2D (Desktop) : Perfect
3D : less than perfect unfortunately
About the same Problems/Artifacts occur, when certain Applications run.
3D Mark 2001SE B330 (Direct3D) :
...Card produces severe Rendering errors
PC Player Benchmark (Direct3D Edition) :
...
almost flawless, but there's a Problem with incorrect Alpha blending around the simple Tree Textures
Looks like the Drivers do not work very well on the Alpha Blending part, and produce significant errors as soon as one, or worse multiple layers of Alpha Transparency are being rendered.
Another strange thing :
The Display Property Page shows a total of 32MB Video Memory...
3D Mark's System Info as well lists the Card as 32MB (27MB remaining for textures in 1024x768x16 Desktop).
That could very well also be a contributing factor to the Problems.
I'd made a bunch of Screenshots (Tools, Digital Out, Rendering examples), that I'll edit into the Post later.
Funny detail :
With the old (unfortunately, I don't know remember which) 3dfx Drivers still installed on the System, it first booted up as a "Voodoo5 5500 PCI Mac" (?)
