I don't know how many people out there will have seen this, but it may
provide some useful info for those looking to upgrade their systems in
the near future.
I may have to go and grab the PIII optimised version to see if it does
make much of a difference to rendering speeds on my Athlon...
Personally I find it interesting that the 1.33Ghz Atlhon running Vanilla
POV beats the 1.5Ghz P4 running an optimised version.
Bye for now,
Jamie.

It's also funny that the 1.2GHz Athlon (which I have) beats the 1.7GHz P4
even though the latter has almost half of MHz's more (not to talk about
price...).

I found it more impressive that the biggest performance boost came from a
new compile - think there is definitely room for an optimised pov patch
branch :)

If someone would plonk down the money for a PIII optimized compiler, and
donate it to the POV-Team, I am sure they would be happy to release an
official version using it...

You mean "a PIII optimizing compiler"?-)

We have the Intel compiler. We're not impressed.
Of course, my primary machine isn't even a PII, let alone a PIII, so what
do I know...

OK, I've done a few tests using the PIII optimised version on my Athlon
1.33Ghz system.
Here are my results, running various versions of WinPOV with render
priority turned up to max, and GUI priority turned right down, oh and as
many systray programs as possible killed off.
Good old fashioned skyvase.pov rendered at 640x480 aa0.3 (standard
quickres.ini modified to add a 500k buffer) :
Watcom 3.1g 0 minutes 19 seconds
MegaPOV 0.7 0 minutes 17 seconds
PIII optimised version 0 minutes 17 seconds
galaxy.pov also at 640x480 aa0.3 from quickres.ini :
Watcom 3.1g 1 minutes 58 seconds
MegaPOV 0.7 1 minutes 49 seconds
PIII optimised version 1 minutes 27 seconds
Pawns.pov again at 64x480 aa0.3 from quickres.ini :
Watcom 3.1g 1 minutes 47 seconds
MegaPOV 0.7 1 minutes 21 seconds
PIII optimised version 1 minutes 16 seconds
These values may be slightly skewed singe I only ran each trace once,
rather than running multiple times each time on a fresh reboot and
averaging results, but to be honest, that was far too much like hard
work, so draw from these numbers what conclusions you will.
Bye for now,
Jamie.

I dare say that if someone were to plonk down the same cash in front of
Nathan Kopp, he'd be happy to recompile MegaPOV with it. Which should
provide even more of a performance boost.

...that it is time to upgrade?

Nathan is in the POV-Team...
