I remember looking for one and finding nothing in my search. (well, nothing that would work reliably with I-War)

And now we have glory. Enjoy.

Is this supposed to emulate a Voodoo video card ? To offer 3D acceleration to those old games from the time when Voodoo was the only accelerator?

General description
This is a Glide wrapper, ie a library that emulates the programming interface for 3dfx Voodoo hardware and in turn allows games specifically coded for it to run on other vendors' graphics cards. Specifically, this wrapper emulates the Glide 2.4 API and a Voodoo I card. It uses OpenGL to do so.

Currently it will only work on graphics cards with either the ATI Radeon or the NVIDIA Geforce family of chips. The new XGI Volari family should work, too, but this is completely untested. It also requires an MMX capable processor from your preferred vendor (read: anything sold in the last hundred years or so).

The number of correctly emulated effects will depend on your graphics card. There are currently three levels of emulation quality:

• Tier 0
  This is the minimum required. Chroma keying will not work, some combiner functions will be approximated.
  Radeon models 7xxx and Geforce 1, Geforce 2 and Geforce 4MX are in this tier.
• Tier 1
  This is a path for first generation pixel shading hardware and will fully support chroma keying but still approximate some combiner functions.
  Radeon 8500/9000/9100/9200, Geforce 3 and Geforce 4Ti qualify for this tier. Note that Geforce 4MX cards do not. This will activate automatically if you have the right hardware. The tier 1 Radeon path will support "AITRGB" lighting while the Geforce path does not, but this feature seems to be pretty obscure and irrelevant. No game I know of uses it.
• Tier 2
  This is a new path for all cards that support the ARB_fragment_program extension. These are currently Radeon 9500 and up and the Geforce FX series.
  This will eliminate all combiner approximations and offer full emulation of all effects. If you're using a Radeon 9500+ and older drivers, this also doubles up as a workaround for a driver issue regarding complete absence of fog.
  XGI Volari V8 theoretically qualifies for this tier, and only for this one, so you must activate the "float shaders" configuration option if you have such a card. I'd be happy to get a few reports in about how/if it works.
