So I have two identical Riva TNT2 M64 16MB AGP cards and both of them have the same issues.
With Asus A7V133-C the 3D functionality is very bad, nothing I tested works properly, Quake 2 & 3, Unreal Tournament (using D3D) and 3D Mark 2001. Graphics glitches everywhere, this what Quake 3 looked: https://youtu.be/b4xKZQIDtzE
Switching to Abit AB-BH6 and now Quake 2 & 3 work fine, Unreal Tournament works if I switch it to use OpenGL but D3D is still a mess, 3D Mark 2001 is total garbage with this setup, even worse than with A7V133-C.
I tried two drivers so far, latest from Nvidia's site and one from previous generation of Forceware.
Since two similar cards have same issues I think it's about compatibility? I have never used these Riva cards when they were relevant, only GeForce cards.
