[Dri-users] Voodoo3 too slow?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi there,

I'm sure this a mixture of FAQs, but I've scoured the manual on
dri.sourceforge.net and made some general google searches, and I'm
still not convinced that I'm getting the performance I should be on my 
3D card.

The short description of why I'm suspicious is that the version of
QuakeForge I use (the old 0.1.1 version) is getting timedemos of about 
14 FPS, compared to around 40 under the old regime (the fullscreen
glide2 GL driver)

I'm using a voodoo3 2000, under kernel 2.4.0, and the debian package
of the 2001.01.26 glide version with the debian 4.0.2 XFree86 packages.

I'm pretty sure that hardware acceleration is working: the correct
messages are in my /var/xdm/xdm.log, glxinfo displays :

direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
client glx vendor string: SGI
client glx version string: 1.2
client glx extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating,
GLX_EXT_import_context, 
    GLX_ARB_get_proc_address
GLX extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa DRI Voodoo3 20001101
OpenGL version string: 1.2 Mesa 3.4

The version of gears from dri.sourceforge.net runs at 75 fps normally, 
and 291 fps with FX_GLIDE_SWAPINTERVAL=0.

Like another questioner I saw in the archives, bus-mastering doesn't
seem to be on:

pear# setpci -s 01:00.0 4.w
0003
pear# setpci -s 01:00.0 4.w=7

pear# setpci -s 01:00.0 4.w
0003

I couldn't see a relevant bios option.

So, with everything seeming to be more-or-less OK, I still get not
really playable performance from quakeforge and tuxracer, the only two 
openGL games I play.

If anyone else has any good benchmarking programs, I'll happily try
them.

But it doesn't seem at all right to only have 15fps on quake on a K6-2 
500 with a voodoo3... it's jerkier than my K5-200 with a voodoo2
was...

Am I doign something stupid?  Is GL performance just not quite there
yet with the DRI drivers?

Hope someone can help..
