Ok, FYI on this subject...
I've had the TNT2 up and running on a Redhat 6.1 system with the older
TNT2 drivers with the 3.3.3.1 version of XFree86. I had a pretty good
frame rate on this system with performer town, esprit, and a number of
apps. There were some various GL bugs, but I figured they'd get fixed
over time. The installation wasn't too bad either. I installed the rpm
and made the change to me XF86Config to load the GLX module and
everything worked for me. It was a lot easier then the 3Dfx-DRI
installation. I recently upgraded that machine to the latest drivers for
the TNT2 (with XFree86-3.3.5) and have had quite a number of problems.
I've heard a number of postings to OpenGL and GLX mailing lists about
problems with the latest drivers as well. Performer is not alone. At
this point, I'd recommend going back to the older set of drivers if you're
expeiencing problems with the new ones.
As far as determining whether you're getting hardware acceleration, we
have a listing for that in our Performer-Linux faq:

hope that helps,
