That sounds like OpenGL in S/W performance to me.
Can you look through /var/log/Xorg.log and see if
you see any error messages?

I don't see your problem.

: alpha[1]#; /usr/X11/demo/glxgears -display :0
27273 frames in 5.0 seconds = 5454.424 FPS
27269 frames in 5.0 seconds = 5453.799 FPS

They are not the same driver :-) The driver on the
nVidia site needs to work on s10, and all versions
of Nevada.

The driver included with OpenSolaris is modified
to know about Xen and will not work on older
versions of Solaris.

You should not see the same performance running on
metal vs running on Xen (running on Xen should be
slower).  There will always be performance lost
going through the hypervisor and we don't use the
PAT in the i86xpv kernel (on top of Xen) today.

I have a GIGABYTE GA-G33M-DS2R, with a Core 2 Duo
E6400 (Conroe), 4G of memory, and an EVGA
256-P2-N549-TR GeForce 7600GS.
