Are you getting the choppiness on the thin client or on the server?  If
it's on the thin client, it sounds like a video driver issue.  I've seen
that come up when using newer nVidia or ATI cards, now that they don't
like to provide programming specs anymore (ATI used to, up to and
including the Radeon 8500).

Try tossing a Radeon 7500/8500 or Millenium G400 in your client and see
if you get better performance.  That worked for me.  Also, see if you
can give something with integrated Intel video a shot; Intel made their
video drivers Free Software last year.  They're not speed demons, but
they do work in 3D.

Do you GNU!?
