Yes, Bagginsbill.

And that's exactly the same tricks I'm using myself for years to get the most out of the low-end machines I owned so far.
Because EFFICIENCY is also a quality feature.

I'd be happy to pay 100$ a piece for an environment setting for Poser, baked on shaders or not, as long as the results look as realistic as those game screenshots and the whole shebang would render in less than 5 min.

It's the results that count, and I bet that 99% of the average Poser users would be a lot more happy with the realism of a "game optimized" scene like those above instead of having to wait for hours to get "accurate" highlights on an otherwise anatomically completely inaccurate Vicky.
