So the game runs but has incorrect colors with images on the main menu and loading screens.. Tried with the latest version of dgVoodoo. Also the performance with dynamic lighting on the LithTech engine is improved with dgVoodoo, but still far from ideal at times.

Remove the DWM8And16BitMitigation shim from the registry in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers.

I would also like to add that it could be the 16-bit color compatibility directly affecting

I found the issue anyway using the 32-bit Compatibility Administrator, seems like it was a compat flag triggering the color issue in-game. Couldn't be dgVoodoo related since other LithTech 1.5 games don't suffer from the same issue, and they are 16-bit only as well.

Which flag specifically?

Seems like it's called "ForceDirectDrawWait", which makes a lot of sense. Description says: "The DirectDraw Blt and Lock calls may encounter device busy situations more frequently in Windows XP than was common in Windows 9x. This compatibility fix adds WAIT flags to Blt and Lock calls to prevent application crash due to device busy scenarios."
