Amazing the amount of self-denial one has to go in order to cope with excuses
for why his favorite rendering engine should not evolve.

No, my question is merely like:  "hey, I can render scenes in povray in seconds
rather than dozens of minutes.  And truly complex ones in a few hours rather
than days."

I'm not impressed with that demo's noisy 4fps display.  I'm impressed to see
scenes with full light transport phenomena set that usually take 1 hour to
denoise being noise-free in a couple of minutes.

This is the future:  tapping all that hidden power that was being ignored so far
because we insist on using a lame-O chip geared at word processing to do math
operations.
