Quake III Arena, Dronez
None of these two companies ships a working OpenGL driver now, so I could not run Quake III or Dronez.
The Expendable Timedemo is one of the older benchmarks we use. Yet, it is excellent for these kind of comparisons, as the frame rate depends very much on the graphics card. Any faster model than the GeForce2 MX 400 would provide even better frame rates.
The SiS chipset is clearly faster than the Trident chip. And the image quality is better, even if you only use the medium quality mode.
