[utah-glx-users] Some G400 benchmark data (long post, lotsa data)

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

Hardware:
 Tyan 1590S (MVP3) with AMD K6-3-400 with 64MB PC100 CAS2
  Matrox G400 32MB dualhead (white box)
Software:
  Utah-GLX CVS dated March 16, 2000
  agpgart-2.2.13.patch dated March 16, 2000
  Kernel 2.2.14 with Jumbo IDE and agpgart patches

I'm subscribed to the utah-glx-devel list - I just read the archives. If
anyone
thinks this data will be of interest there, feel free to copy it.

This is a rather slow system to use with a G400, but it makes for some
rather
interesting points about the benchmarks. At any rate, First
Person Shooter
Frames Per Second aren't my top priority, but q3test is the best
benchmark
I have available, at the moment.

First off, AGP1X vs AGP2X doesn't seem to matter much, as someone had
mentioned in the developers' list. Second, framerate seems to be a
rather
weak function of everything, including resolution, except for lighting
and
geometry detail. Lighting is the strongest driver of performance, (or
lack
thereof) geometry detail comes in a not too distant second, and
everything
else is in the mud.

The "fastest settings, except" and "high quality ++, except" probed each

option one-by-one. The "++" on high quality comes from pushing texture
detail to max, instead of one step down. The bpp was done with some
linkage between display buffer and textures, I wasn't exhaustive, there.
I
saw no point in bothering with a 16bpp framebuffer with 32bpp textures.

For the split quality, I tried lighting and geometry at high quality and
all
others at low quality, and vice versa, just to see a few combinations of

function. Even taken together, the rest of the quality settings were
pretty
much in the mud. It's worth noting that resolution was a stronger factor

in the run with vertex lighting, low geometric detail, all others at max

quality.

Finally, I have some GLX startup logs from Pseudo-DMA, PCI-DMA,
and AGP with gart_mask=1 and 2. I normally run with the gart_mask=3,
but the results are the same as 2. I use a 4MB command buffer and 8MB
DMA buffer for both PCI and AGP modes.

I hope somebody finds this vaguely interesting. It would be interesting
to me to see some of the same runs on a stronger CPU. If anyone would
like me to run specific benchmarks here, I'd be happy to try and help.
