It seems that Windows 2000 DDK contains S3 Virge driver with OpenGL support through MCD* driver model. Has anyone ever tried OpenGL MCD on S3 Virge? Do you know if there is a compiled version of this available somewhere?

I know that there is a D3D wrapper for GLQuake, a S3D wrapper for Quake II-based games (by Techland) and Brian Paul's MESA 3D OpenGL ICD driver for S3 Virge cards. However, none of these works in the windowed mode (and this should).

*) MCD = Microsoft's OpenGL software renderer, where a hardware vendor adds acceleration only for features that are supported by the cards (the scene is rendered in the framebuffer, but polygons with unsupported features are done in software). I have successfully tested OpenGL MCD drivers for Matrox Millennium I & II, ATI Rage II+ and ATI Rage Pro (the one that was available before ATI finished full ICD)

I found mentions about MCD for Virge in this discussion:
https://groups.google.com/g/comp.graphics.api … knU09GfQJ?pli=1

There are some broken links to MS web:
https://www.opengl.org/archives/resources/faq … cal/mslinks.htm (the links don't work even with web.archive.org)

Windows 2000 DDK can be downloaded here:

I just quickly checked the archives and they do have S3 Virge driver sources with MCD files:

S3Virge

SUMMARY

This sample display driver demonstrates the implementation of the following Windows® 2000 features:

DirectDraw
Direct3D
Video Port Extensions

BUILDING THE SAMPLE
Build the sample using the standard Windows 2000 driver installation guide. There are no special requirements for installing this driver. Once built, it produces the binary S3mvirge.dll. Both checked and free builds are available.

This driver works on both x86 and Alpha platforms, and the code builds properly with Visual C 6.0. The driver supports Plug and Play, Power Management, VPE (Video port extensions), DirectDraw, Direct3D, and OpenGL/MCD.

RESOURCES
