Dan.
Funnily enough. Ive tried to do EXACTLY the same thing, but with differing
effect. I tried a stock install or redhat 6.1 based upon a previous 3dFX
install( http://www.denifs.demon.co.uk/linuxperformer <- for those outside
SGI, http://homer.reading.sgi.com/~dcave/linux3dfx-performer.html for those
in sgi.
Now.. I did use the nVidia x server ( 1646392 Jan 11 13:06
nvidia-x-glx-335-i386-dyn
_tar.gz ) which is actually 1. older and 2. a smaller binary than that of
the redhat install (6.1) and had bugs which i descovered (problems to do
with a rubberband/marquee select and doesnt refresh the desktop when you
de-select/click desktop)
-rwxr-xr-x 1 root root 3262980 Sep 24 23:21 XF86_SVGA.redhat6.1
-rwxr-xr-x 1 root root 2756261 Jan 11 14:16 XF86_SVGA <-- nVidia
TNT Xserver
I also have sym links
lrwxrwxrwx 1 root root 27 Jan 11 17:05 /usr/lib/libGL.so.3
->/usr/X11R6/lib/libGL.so.1.0 <-- nVidia LibGL.so.1
I didnt get 20 fps when running perfly on esprit.pfb, more like 6. im using
the Mesa 3.1
1580266 Jan 4 13:08 MesaLib-3.1.tar.gz.. Dan, do you have a
/usr/X11R6/lib/LibGLU.so.n?
Id be interested in any feedback (especially from the performer guys!)
Kind Regards
