Hi all,
Is  it just me or is POV 3.1d slower than the last version?, Especially when
using rad and AA (9x9 rays)

  Of all the tests I ran prior to it's release the opposite was true in
all cases. While I ran no performance tests on radiosity I did casualy
run a couple files with it turned on and recall is rendered surprisingly
fast. If you are running an old 486 machine you might have suffered
a performance degradation but anybody with a pentium or better machine
should see a performance increase in several different types of rendering
situations.
  Often times if it's rendering slowly it's more related to the construction
of the scene than it is anything else. Transparent textures, multiple csg's,
and lots of reflection all take their toll on the the old render clock.
  Take a look at the test results I submitted to Chris Cason either by
looking in povray.announce.frequently-asked-questions or hit the link below
to go straight to it.

I am running on a AMD K6 233, maybe its just windoze 987, being a pig.

I have just got thwe msdos version od 3.1d, so will be rendering complex
scenes in that from pure dos, that should be much faster! - I like to start
my renders before bed, and have them ready when i get up :)

I am curious, just how much faster does the DOS version render? Can anyone
give me an approximate percentage? After all, a scene that takes 20 hours
being rendered in 19 hours really makes no difference. It would need to be
20-50 percent faster to really impact.

On the subject, what about the Linux version?

Thanks

I have heard conflicting reports on this issue. Personaly I have experimented
a bit but could not detect enough of a difference to warrent installing a dos
version. You might take a look at the Pov benchmark page and see if anybody
has posted comparson times for the same machine using the different versions.
There is a lot of data available there if you have the time to sift through
it all.

I've noticed faster renders using DOS versus Windows, on average about 8
minutes less per hour. But it is subjective to the scene file and the
machine setup I think, so if anything you might say Windows takes 105%
to 120% longer to render. The variances people see doesn't permit a firm
statement on it I believe. Suffice it to say Windows will probably
always be the slower.

I have installed POV for dos, and use it for overnight animation renders,
and it is well worth it!!!

a performace of 120% on avaerge make a huge difference when rendering
hundres of frames!!

On this topic:  I did some testing of this and, under windoze 98, the
POV-Ray rendering engine gets 85%-95% of the processor time.  I don't know
how this translates into relative speeds, though
