Hi Alan,
I think we're getting closer ;-)
Did you check if the via_agp module was loaded without problems and
before the agpgart module. If I load the intel-agp module after the
agpgart module I also get only approx. 270 fps. In this case there is
also a entry in /var/log/XFree86.0.log:
(II) RADEON(0): Direct rendering disabled
As you mentioned ealier that you tried the drivers from ati you have to
consider that these drivers exchangend your opengl libs. So this could
also be the reason.
Other things you can check:
In /etc/X11/XF86Config-4 under section Module
Load "glx" and
Load "dri"
are necessary. Also you must have the rights to access the dri Device.
So best do your tests as root.
If in Section DRI mode is 0660 you have to put users in the group video
so that they can access the dri device.
Also consider to switch your driver in Section "Device" back to "radeon".
I have to say that I also tried the binary only drivers from ati because
I wanted to get the tv-out working. But I had problems with stability
and there is another annoyance with the ati drivers: You can have either
Xv fullscreen or OpenGl but not both. So I switched back to the standard
X drivers and am quite happy with them.
Please consider to ask your questions to the list!
Greetings,
Michael
