knowledge?
Did you used WinGUI installed over previous version ? Did you used benchmark
from menu of from file ? Did you had the same priority settings verified ? Both
had energy saving off ? Non other applications ? Any other benchmark application
tested ?

Well, I seem to remember someone once saying that, "if you idiot proof
things enough, only an idiot will want to use them." I think in some
respects Windows is starting to approach that level. The blasted OS
already liked to do incomprehensibly useless things in Win98 (like
letting some programs spawn 20 dial-up connection wizards if they
couldn't access the internet), now it does even more stuff behind your
back in XP. lol

Was that an Intel or AMD CPU?

Sorry, it doesn't make any sense. You sure you didn't forget the
antialiasing on the 1GHz machine ? This alone would make these figures
consistent.
The only other reason I can think of is a RAM issue (not enough RAM on the
2.8 GHz machine) but I'm not sure the benchmark is such a RAM hog.

I've now been able to try again.
Second try on the 2.8GHz machine: 2446 secs (vs. 13361 on first try).
Last night, I hit the Render button and went to sleep. Next morning PC was
in sleep mode (a deeper one than I usually see on the 1.0 machine). and the
next morning the Message board said 13361 secs.
This morning I hit Render again and went to work. When I was able to check
the PC again, it said 2446 secs.
So two wacky things going on:
1) WinXP's overagressive sleep mode.
2) WinXP's extreme neurosis about the state of its connectivity to the
internet (I've seen renders hang due to a warning message from XP).
Both cases 512 x 384 AA 0.3 of benchmark.
Will try new experiments.

As far as I know, Windows XP does little but tell the computer's BIOS when to
go into sleep mode. Also, if going into sleep mode were based on processor
activity, the computer would never go into sleep mode.

Make sure the auto-update features are off and MSN Messenger is shut down.

Shouldn't happen in Windows. Even if a window popped up in front of POV-Ray it
should keep tracing in the background.

That's the cause of the inconsistancies.

If the computer's sleep state were based on CPU usage the system would never
enter sleep mode. Any OS you use has to constantly run through instructions in
order to keep the system running smoothly. Take a quick look in your Windows
task manager (go to the performance tab and don't move the mouse at all).
You'll notice that the processor utilization hangs between 0% and 2%. Remember
that, even though you aren't going anything, background processes and services
still need a small chunk of CPU time to do their thing.
Knowing that, you could argue that CPU utilization can be checked before the
computer drops into sleep mode. I don't believe this is easily possible. CPU
utilization is (I believe) an abstraction made by software based on how it
divides CPU time between the various tasks that are running. Implementing
something like this in a computer's BIOS would probably be impossible without
changing the entire architecture to the point of having the BIOS handle multi-
tasking, a choice that would be very expensive and not allow for the same degree
of freedom that OS developers have.
This is getting a bit off-topic. Followups set.

This is definitely happening.

Which chip? That would be nice to know.

Most likely a Pentium 4. Most people refer to Athlons with the AMD name
(Athlon 2800+).
