3D performance on everything else sucked, but the FFT was exactly the same, I think it always uses software for line drawing, just the software in the GPU drivers isn't as good as the full software driver.
To switch, just change the driver line in your xorg.conf, I changed mine to " Driver "vesa" ", which changes the OpenGL stack to Mesa's full software renderer.
