Hi Mark,
The new binary seems to be a great improvement on the original 3.5
verison, but it's still quite a bit slower than Micha Riser's
custom compile for PIII (running here on a PII).
However I've come accross a major problem with Micha's version today,
there are many scenes it won't render. This is after clobbering the
original binary that I d/l'd from Micha's site some time ago and
getting another binary from the same site today, maybe I'll try the
icc compile from there as that may have been the version I was using
before I did the 3.5c install.

I found that the binary that's the quickest and works properly with all
pov files is the one optimised for athlon.
I got this in my results at the end of the trace:
Total Time: 0 hours 36 minutes 60.0 seconds (2220 seconds)
^^^^^^^^^^^^^^^^
I presume that this but is still in 3.5c though I havn't read the change
log.

You are running a compile for PIII on a PII? Why are you surprised that it
doesn't work?

Read it again...the PIII optimized compile is the faster one on his
machine.

With computers nothing surprises me, and it does work, just not for all scenes.
You'll no bout be very surprised to find that the Athlon optimized binary works
perfectly on the PII.

Yes, but as the Pentium II does not support the SSE instructions it is
surprising that it works at all! Apparently the compiler used doesn't add a
lot of SSE instructions...

No wonder assuming the Athlon specific compile does not use 3dnow
instruction set extensions ... because without them, the instruction set is
basically identical.

gcc 3.1 does not use the SSE instruction by itself, you would have to use
inline assembler to make it use them. So there is porbably only a few
PIII-specific instructions left that it uses at all. This explains why it
sometimes works on a PII as well. I had even turned off the SSE
optimization when I compiled with the Intel compiler (only some of the
5-components colour calculations could have been vectorized anyways)
because it did not result in a speed-up, but rather a slow-down.
