Re: [Dri-devel] Mach64: Patch for the CVS DRI trunk

[Carl B. <afn...@af...>]

Hey,
Great, nice to see it working on DRI.  I just wanted to note that after 
quite a bit of hassel, I got utah-glx working with x-3.3.6, but only 
options 0, and 1 work, and they get about 190fps, though I only have a 
550mhz processor.  It's nice to see dri working at least the same rate.
