I hope to find the time to compile the mach64-0-0-4 branch at the weekend or at least early next week. I am still using the driver without dma with which I get about 30 fps playing UT or Quake3 in 640 x 480. I am curious how the driver performs now. It would be quite good to make a short list of how one can measure the speed of the driver accurately under different settings. I don't know anything about graphics driver programming so I don't know how I can measure "dma speed" or other crucial things. Greetings, Michael |
