How to turn off mosaic preview?
I didn't turn it on...

command line is empty or only contains: "width=900 height=700 +a", no changes in
quickres.ini.

but 3.7beta31 renders with mosaic preview (no, not the multicore-cpu-cells).

tried to apply +SP1 +EP1 to the command line or even +SP0 +EP0 without any
effect -- the rendering starts with a mosaic preview of about 70*70 px.

strange. I don't get this (mosaic works when I request it, but isn't on
otherwise).

Is it really mosaic preview? Do you get plain-colored squares, that then get
replaced with smaller squares, until you get 1px squares making up the
final image?

If the image is rendering in little blocks instead of line-by-line top-down,
that's expected. It's not mosaic preview. It's how the multithreading
feature of POV-Ray 3.7 works. The image is divided into tiles, and each
thread is assigned a tile to render. When the thread finishes rendering a
tile, it starts with another.

I guess that's what Physiker meant with "multicore-cpu-cells".

How about radiosity? The pretrace looks like mosaic preview, too.

Yes, thank you, you are right: It's radiosity in my scene. :-)

So radiosity mosaic preview is new in beta31?!

First off, let's stick to the term "radiosity pretrace", as its intention is not
to give you a preview, but to collect radiosity data before the main render.

No, the radiosity pretrace is nothing new. It can be seen just as obvious in
3.6.1c, for instance.

With the SMP extensions, however, the pretrace was no longer that obvious until
(and including) beta.30, as it would be done in the same "SMP pass" as the main
render, i.e. POV would "first" do both the pretrace and main render for the
first SMP cell, "then" the pretrace and main render for the second SMP cell,
and so forth (of course, "first" and "then" to be understood in the SMP
context).

With beta.30-rad1 the concept was changed to do an individual "SMP pass" for
each pretrace pass, i.e. POV will now first do the 1st pretrace for all SMP
cells, then the 2nd pretrace for all SMP cells, and so forth, and finally the
main render ("first", "then" and "finally" in this case denoting real time
relationship).

So in some sense - yes, the fact that radiosity pretrace double-features as a
kind of mosaic preview was (re-) introduced with beta31 (or, to be more
precise, with beta30-rad1).

It has always been there in this double role in POV 3.6 though.
