I'm a little confused at this point. Does X 4 support utah-glx? Or are you
referring to the GLX module that comes with X 4? I had to tweak my X 4
XF86Config file to load that module in order to get, for example the GL
screensavers in xscreensaver to load, but once I did I found the
performance very comparable in my entirely non-scientific comparison to the
old X 3 + Mesa performance. I never installed utah-glx with X 3.
