Hi, in my various retrogaming tests, I've tried lot of time the so many times obscured S3 Virge based card that lot of people was renaming as decelerator because 3D rendering hardware acceleration was affected by poor frame rate in comparison with software rendering. Well, in my test I've tried a OpenGL32.dll customized for original GLQuake and I was shocked to see that with this minigl subset (I think that being not supported OpenGL extensions, this dll built by S3 itself was a wrapper to call Directx (few) supported calls instead of OpenGl minimun ones) this card accelerate the game at 640x480 with real texture filtering and generally a good image quality (also with a ~<>10 fps goal in mind). Did you remember it? I think that S3 Virge was really a good accelerator talking about features supported when there were no alternatives in the 3d card panorama. Soon I'll upload some screenshots.
