Hello,
there is a new (second), unofficial Version of POVRAY at
http://students.washington.edu/sschmitt/pov/ for download. This Version is
optimized (with support from Intel) for PIII/Athlon and P4. And I'm deeply
impressed how immense the difference of rendertime between the non-optimized
and the optimized code is.
I use the POVRAY-File chess2.pov to compare CPU's at http://www.tabsnet.com/
since the Beginning of 2000. I hope, someone of you send me an Result of an
P4 running the new, optimized POVRAY-Version.
Here are some results of my Computer.
Rendertime in second with this Parameter :
-d -q9 +w800 +h600 +b1000 +r3 +a0.300 +v1 +ft -ichess2.pov
Non-optimized 1'st optim. 2'nd optim.
Athlon 1200 MHz 542 sec. 436 sec. 300 sec.
Pentium III 667 MHz 1056 sec. ---- 689 sec.
Tilly

IIRC, this was discussed in April in a thread in this group that I
started, but the optimised version definitely makes a difference to the
performance on my system.
Bye for now,
Jamie.

<sigh>
That'll teach me to read articles more thoroughly before I reply to
them...
I managed to miss the important concepts of _new_ and _second_
versions...

Woha, what a difference! My Duron 700 got 7m10s with those settings,
as opposed to 12m52s with the official version. Any chance MegaPov or
v3.5 will be compiled with this?

Which "Non-optimized" version of the official 3.1g for Windows are you
using? I guess you are _not_ using the Visual C compile available as an
optional download on ftp.povray.org?

The "not-optimized" Version I mean is the Official Version that we can
download from www.povray.org . The first PIII and P4 optimized Versions from
http://students.washington.edu/sschmitt/pov/ are from April, 2001 I guess.
The second, more optimized (PIII/Athlon and P4) Versions are just a few days
on the Server.
But I used the MS-VC-Version too. But the Intel C 5.0 and 5.1 compiled
Version is much faster.

OMG.. I hadn't realised until now just how slow my P200MMX is. I gave up at
line 209 as the render time was already 36 minutes!!
I NEED to upgrade.. with 3.5 just around the corner, that's a good enough
excuse, right? :-)

You'd need an excuse? j/k! ha ha ha
Got to 800MHz finally here and you know I want to upgrade already!

The numbers for my 1333 MHz Athlon are:
Off. compile 482 s
1. optimized 391 s
2. optimized 267 s
This is just as good as getting a new 2.4 GHz processor! And a lot
cheaper!
