Purely my fault,

using a new demo scene, there is no such problem anymore.
At 400:225 all scenes of the old "300" material setup needed a bit more than a
day - the new setup allows to render the materials with 1280:720 within the same
time...

And as you can see, it isn't only a sphere on a plane... (

).

And - trust me - the deeper you look in the newsgroups intestines, the more you
will discover. Of course the same is true for private websites, IRTC etc.

By example, Samuel Benge discovered a way to use 65536 samples with nested
average patterns instead of the usual 256 and I don't understand how he did it.

Or let's take Rune's good old grass demos. He managed to construct a pigment
showing to the camera and simulating a 3D grass population.
I'm sure this trick is worth for many new materials alone - at least, if I can
delve deeper into the code...

etc. etc...
