I had an S3 ViRGE too. It really was a decelerator, and the number of games that actually supported it was minuscule. I managed to run GLQuake, but without any textures - just shades of gray - and even that ran at most a couple of frames per second. But there was another game - Terminal Velocity - that actually looked a lot better with hardware rendering, although it was still slower than software rendering. So, I would run it with hardware rendering to enjoy flying and then restart the game with software rendering to actually fight the enemies. :)
