[PD] very bad GEM performance

Hallo IOhannes, others!

Yesterday I compiled the new GEM from cvs with the following configure 
options: ./configure --disable-ARB

Now I have a very bad performance (which I haven't had before):
e.g. if I play a simple movie, the output of top says:

2000 root       6 -10 92624  20m  68m S 83.0  4.1   1:06.93 XFree86
4687 holzi     15   0 50036  11m  26m S  2.3  2.4   0:00.90 pd
2233 holzi     15   0 29892  15m  26m S  0.3  3.1   0:01.75 kdeinit

So XFree86 uses 83 % cpu (and sometimes much more) - but only if I turn 
on rendering.

I also get the following error in the shell:
   Xlib:  extension "XFree86-DRI" missing on display ":0.0".

Can I use some other configure options, so that the performance is not 
that bad anymore ?
