Just about any Windows game that truly supported Glide will run well with nGlide. Only a handful of games and demos will not. Lots of games support 3dfx cards in the sense that they use Direct3D or OpenGL and work with a 3dfx card.

The "22-bit" color rendering was an aproximation of how the Voodoo 3 cards handled 32-bit color. Any Voodoo could handle 16-bit color, but the Voodoo 3 did not quite have true 32-bit functionality. Voodoo 4 and 5 cards could hanle 32-bit color without compromises. Since this was a distinctive feature of the Voodoo 3's output, I doubt anyone has ever sought to emulate it. True 32-bit support will always look better.

Some people can put together systems that contain a Voodoo 1 and Voodoo 5 card so they can run DOS games that refuse to run on a Voodoo 2 and have the Voodoo 5 for 32-bit color, 4xFSAA and fast Glide support.

I've been very impressed with nGlide. It doesn't have many configuration options but it does have exactly the most important ones, high resolution and vsync among them.

Regarding 3dfx's "22-bit" color (a term which I believe was used with the V2 as well) for me the classic example is the rocket trails in Quake III. Fire off a rocket while standing still and look through the layers of smoke it leaves. On real hardware you'll see a fair bit of dithering thanks to the non-32-bit color depth.

The Voodoo dither stuff could be done in a shader. Whether anyone wants to sacrifice some sanity to write a double lookup post-process shader is another question 😁

What's that got to do with this term? 22-bit simply means that the RAMDAC filtered the 16-bit image to smooth it out. The reason those trails look horrible on 16-bit color hardware is that id was obviously not giving a damn about how the game looked on then-"outdated" cards. If you play Unreal Engine 1 games the effect is far less pronounced.

I see. Perhaps I've misunderstood the context all these years.
