Hello,

I'm using the xorg state tracker driver r300_drv.so and some functions seem to not accelerated. Here is the perf output when moving a window:
-     68,56%                X  libc-2.14.so                          [.] memcpy

You need to enable 2D acceleration with Option "2DAccel".

Comment 7 Martin Stolpe 2011-10-19 10:52:33 UTC

My fault. I had 2D acceleration disabled because of graphical glitches.
