Especially given the fact that it's software only unless you've got a 3DFX card. According to a friend of mine, the Matrox G200/G400 GLX support is the thing to watch. They have almost full support from Matrox and John Carmack is providing optimisation tips. Linux is also lacking in the very large DMA chunk area, which is something that the 2.3 series of kernels will apparently address. This should allow a large speed increase, as programmers will be able to decouple the graphics card and the CPU to a greater extent. Toby.
