How do you know it's dgVoodoo, and not the game itself that's not working in Vista?

Does dgVoodoo2 support Windows Vista, specifically 64-bit?

I can't find any clear documentation on why Vista wouldn't be supported, but 7 is. What's the difference between the two that would prevent dgVoodoo2 working?

I'm trying to get Direct3D 8 games such as Splinter Cell working on Windows Vista Ultimate 64-bit. However, when I choose the necessary configuration as recommended by pcgamingwiki, the game crashes immediately before starting. The crash error report is empty so I can't diagnose this further, so I don't know where the issue is.

Can anyone give a clear reason why dgVoodoo2 wouldn't work on Vista?

dgvoodoo 2 works with windows vista. I have tried with my laptop.

dgVoodoo should work on Windows Vista because it does not exploit any OS feature that is not available with Vista for D3D11.
I just don't mention Vista in the readme because I myself never tested it on Vista, so, just to make sure.

Because I was able to run the game (albeit without the D3D8 features enabled) on Vista without dgVoodoo2.

Maybe entirely unrelated, and I'm not sure which of the SC games included it was now, but back in the day I bought a "splinter cell trilogy" bundle, and one of the games refused to run on my then top-of-the-line XP64 system; I think it was something related to the DRM that differed between the three included games, that was not updated for one of them to work in a 64bit environment.

(My XP64 PC did not have any voodoo hw/sw installed, so it may be unrelated to your issue, since you wrote you had your game working without the dgVoodoo2. I cannot retest on my Vista, since it is 32bit)
