Compiz with an ATI X1200

Hi,
I have a problem with compiz running with an ATI X1250 (integrated
graphic chip on a gigabyte mainboard). I have installed the
proprietary drivers (version 8.45.4) on an Ubuntu gutsy machine. After
that I changed my xorg.conf according to the wikipages of the
compiz-fusion project. [1], see below.
Direct rendering seems to work:
$ glxinfo | grep -i direct
direct rendering: Yes
...but if I run compiz the system gets slow. There is always a latency
when you open a menu, move a window or things like that. I have no
idea how to solve this.
If I run glxgears (compiz disabled) I get the follwing output:
$ glxgears
3075 frames in 5.0 seconds = 614.830 FPS
3071 frames in 5.0 seconds = 614.184 FPS
With compiz enabled I have round about 500 FPS. I think that is not
much. When I run glxgears one core of the CPU seems to have 100% load.
It seems to be software rendering or am I wrong. Does anybody know a
solution for my problem?
Thanks in advance,
cheers,
Christian
