Hi,

> > 2000 fps confirmed on my r50p.

yesterday i finally talked X into giving me hardware 3D for the radeon
9000, sitting in my docks pci port.
(Hehe, this is not even possible with the widows drivers: supersavage as
primary head without d3d and radeon as secondary with d3d.)

Problem is, it's not really fast. glxgears gives me about 170 fps and
glxinfo gives the following table:

   visual  x  bf lv rg d st colorbuffer ax dp st accumbuffer  ms  cav
 id dep cl sp sz l  ci b ro  r  g  b  a bf th cl  r  g  b  a ns b eat

May this be due to pci? Or is it because i'm using dualhead together
with the supersavage? Can i optimize anything through driver settings?

Any hints very much appreciated.

Andre.
