Hello all,
after your latest fixes I've to report the following issues together with my
Voodoo5 5500 AGP.
First of all:
Do I have to use the Mesa-4.0 CVS tree?
Keith what was the name of the path variable, again?
1. UT 436 show a mirror hall effect (it seems to me that there are some
redraw/flush events missing). First I can stop it with the ESC key but later
it crash and hang the whole X server.
2. Parsec show some texture corruption.
3. Triangle calculation is much slower. For example "ipers" goes down to ~11
fps where the trunk gave me 15~16 fps on my 1 GHz Athlon II SlotA (with
Glide3 _WITH_ 3DNow! optimizations on). --- Yes, I got it working, again.
Later more on this topic.
Second example, VTK (sphere-bench.tcl-2.1, stripper mode) goes down to
~1450kpolys/s where as the trunk gave ~1640kpolys/s.
mesa-3.5:

Find the best sphere resolutions for your card, launch *bench combinations*
and send us your results (copy the session with <Control />) along with a
complete description of your system (VTK/OS version, hardware description).
System :
- i686 running Linux 2.4.11-pre2-preempt
- VTK 3.2.0 (rev: 1.995, 2001/10/04 00:04:14)
- OpenGL
- Visual is 1280x1024, truecolor/truecolor/24
- Tcl/Tk 8.3.2
Defaults :
WARNING : $active_camera GetClippingRange was 2.45199 4.78654 , should be
0.348564 17.4282
- VTK : wrong, please report us your values...
- Rotation limit, increment, number : (300 by 30) x 3
- Sphere opacity (if transparency activated) : 0.3
- Sphere radius and small radius (if small_sphere activated) : 0.9, 0.5
- Combinations : [stripper] [small_sphere] [] [transparency] [wireframe]
[texture] [texture, transparency]
NOTE : the 512x512 and above sphere resolutions are *really* high, use them
carefully, as it might hang your system for a while. Moreover, they have no
real signification in 400x400 or less window.
IMPORTANT : move the camera a little to interact with the sphere before
playing with this bench...
Benching for sphere resolutions : 32, 64, 128, 256, 512
Setting(s) : window is 400 x 400, sphere radius is 0.9
Option(s) : [stripper]
32x32 : 174.6 kpolys/s
64x64 : 974.4 kpolys/s
128x128 : 1156.0 kpolys/s
256x256 : 1228.6 kpolys/s
512x512 : 1452.4 kpolys/s

More on this (how you build it, better compiler optimizations for
Athlon/Duron), tomorrow.
