You missed my point: The image created is not identical due to the mentioned
bugs, and some features are disabled. Hence, the results of comparing 3.6
release with 3.7 beta just have *no* validity whatsoever.
And believe me, I know very well what the real speed of POV-Ray 3.7 compared
to 3.6 currently is. The benchmark is still 10% slower than rendered 3.6
(and that compares the Visual C builds), and there is no magic in there for
the multiprocessor case - you get four times the speed of a single threaded
render, not more.
