Hi, I have a quick question. As someone mentioned a little while ago,
even if you set POVray's render priority to Highest, it still gives some
resources to other programs. Is there any way to give POVray a higher
render priority than "highest"? Possibly with a patch?

If you're running NT, you can use the Task Manager to set the
process priority higher - all the way up to "Realtime" if you're
crazy (that will make POV take priority over critical system
stuff, however.)
I don't know if there is a way to change process priority on
Win9x, though.

If you want the absolute highest priority start pov,
pop up the task manager window, and close everything
including windows explorer. When you finish running
pov you will have to reboot but that's the only way
I know of to give it total control. I don't know
how much of a performance boost you can expect but
I wouldn't think it would be very much. If you have
a scene that looks like it's going to run for several
hours it might be worth the effort. If you are thinking
that you will get your ten minute render time down to
5 minutes just forget about it. Ain't going to happen.
Raytracing is a time consuming process and impatients
will get you no where. Of course if you can stand to wait
a short while intel just release an announcement that
their pentium III chip will be on the market soon.
That will really help your rendering times.

Hmm...I'll try that. On my old 486 I have to squeeze out every ounce of
speed I can :-)

As far as I know, there are only two main improvements in the PIII chip
(somewhat higher frequency aside). It has the KNI (also called MMX II),
which is of no use to POV. And it has a larger on-chip L1 cache. I'm not
sure about the effect of this; but I do know that my Celeron, which has 4X
less L2 cache than a PII, is still as fast at POV as a PII at the same MHz.
So I'd guess the effect will not be too great (in POV)
And Intel had the "great" idea of this identification code in PIII... Big
Brother Inside.
Anyway, I'd wait for AMD's K7. It has somereally impressive stats and is
probably much better value for your money (a lot of money in both cases)

How much time until that K7 comes out? I think I'll buy that.

I looked at their press release web page and could not find
any real performance or operating data available. Do you know
what the top end will be on these - 400mhz more ? and if they
will operate at faster buss speed than their predecessors.
They had about 8 different pages to visit and not one had
any information except that yes they have devoloped it and
yes they plan to sell them.

Got to http://www.tomshardware.com he has info on the K7, they will be a
slotted chip, starting at 500mhz I believe, and YES they will have a
faster bus speed... something like 166-200mhz. Also they will have
(reportedly) much improved FPUs. However, the K7 is awhile down the
road (2H 99 at earliest) especially since the K6-3's were supposed to be
out the gate in early January and have yet to hit OEM's

I think they start from 500MHz and use a 120MHz bus (at least later on).
Don't quote me on this, though.
And I rarely read Intel's press releases (or AMD's, for that matter).
They'll just say it's the best thing that has happened since sliced bread
etc. etc.
If you want a bit more objective info, check out some processor news pages;
they also have tech info. They had info about Katmai (PIII) already in
November.

The best way to get MOST priority is to run POV as shell.
To do so, you can either change your system.ini line and find the line :
shell=<drive>:\<windir>\explorer.exe to
shell=<drive>:\<povdir>\bin\pvengine.exe
This isn't very comfortable, and will cause you to have to boot to dos,
edit, reboot and run POV..
Not a favourite to do.
I recommend using a program for it, the one I prefer is only 11k, and
then choose what shell to boot.
I use it for my different setup's (POV/Exploder/Reveal/Evwm/Litestep)
Here is a link to it :
