Hi Justin Rogers, you recently wrote in povray.programming:

You can't apply an observation from a commercial program to general
software! Maybe the single-threaded ones were badly written, and the
multi-threaded ones were rewritten. Maybe it's a subjective impression
because the UI was more responsive (seperate UI and render thread).

Just because some commercial apps have multithreading, doesn't make
them render faster. I doubt that more than one thread is used for
rendering (unless it's running on a multiple CPU machine).

It's totally illogical that POV-Ray could render a scene faster with
more than one rendering thread. If you don't think so, I'd like to
know how this is supposed to work, because then I'll create a thread
for every pixel and have the image rendered faster than you can
blink<g>.
