2024 - Update
Turns out I didn't need to disable the W-Buffer in RivaTuner, but rather change the 16-bit W-buffer format from fixed point to floating point to fix the graphical issues in Unreal. However I don't think there's something like RivaTuner let alone an older version compatible for Windows 95. If there's a alternative program compatible with Windows 95 that allows changing the W-buffer format, let me know.

I'm currently having graphical issues with games like Unreal (via Direct3D renderer). However I did find out that the issue relates to the W-buffer, when I disabled it via RivaTuner (when I had the 3.68 drivers installed) the weapon models somehow rendered properly.

Is there a driver for the Riva TNT around that has a proper W-buffer or is it entirely a video card issue? It's also an OEM card I got off a Compaq. (Diamond Viper V550 16MB)

Right now I am currently using the 2.08 drivers, but if there's not a proper driver, I may have to deal with disabling the W-buffer with 3.68 instead.
