There is still one 3DNow! bug (texture related) remaining in Glide3 at least
for the Voodoo4/5.
I had it going on my older Banshee and Voodoo3 but after Joseph Kain (former
3dfx employee) fixed another bug it is broken, now.
So there are _NO_ 3DNow! enabled Glide3 binaries available from any
distribution.
I worked on it but can't solve it 'cause I learned assembly on 68k...;-)
But I have pointers and could help.
Second:
I had three times (3x) higher numbers for Mpixels/sec (~160) with SGI's
"tenmillion" even with the "slower" Voodoo3 that time.
Mesa/demos> ./tenmillion smooth
running on SunWave1 (Mesa DRI 20020221 Voodoo4 x86/MMX/3DNow!) Wed Apr 3
18:12:02 2002
visual: 0x23
50 pixel triangles, 90 triangles/strip, 1 strips
vertex data: v3f
smooth shading, zbuffer off, light off, texture off, immediate off
test time: 1.511 secs.
geometry rate: 929234 triangles/sec
fill rate: 46.462 Mpixels/sec
Mesa/demos> ./tenmillion area=3 smooth
running on SunWave1 (Mesa DRI 20020221 Voodoo4 x86/MMX/3DNow!) Wed Apr 3
18:12:18 2002
visual: 0x23
3 pixel triangles, 90 triangles/strip, 4 strips
vertex data: v3f
smooth shading, zbuffer off, light off, texture off, immediate off
test time: 1.999 secs.
geometry rate: 4566448 triangles/sec
fill rate: 13.699 Mpixels/sec
draw_strips_count: 1
I had comparable numbers (~160 Mpixels/sec) with the Accelerated-X beta VSA100
test driver and ~ 6.500.000 triangles/sec for the second test case on my 1
GHz Athlon II SlotA.
So there must be an optimization missing for the Voodoo4/5.
Third:
After the Mesa-4.0 merge some numbers are slower (ipers dropped from ~16 fps
and > 400.000 Poly/sec down to ~13 fps and ~350.000 Poly/sec). Best case (no
textures and fog).
