This is the output: x11perf - X11 performance program, version 1.2 The X.Org Foundation server version 10602901 on :0.0 from heretic Fri Jul 31 00:06:24 2009 Sync time adjustment is 0.1073 msecs. 3200000 reps @ 0.0018 msec (554000.0/sec): Char in 80-char aa line (Charter 10) 8000 reps @ 0.6963 msec ( 1440.0/sec): Copy 500x500 from window to window The next thing to try might be to install the drm modules that came with the mesa library. I would expect that like CPU operations the GPU operations can be optimized so a later code could have better results. Unfortunately. unlike Intel ATI did not hand out optimization manuals for their chips so there is not much hope in improving the performance.
