Thread in p.a-u ...

OK ... where are the most GHz ??? who can trace this scene with more than
1PPS ???
I'm rendering in 1024x768, no AA, no Radiosity ...

BTW: I tried +QR, but I had wrong parameters, and MP06a crashed in the first
pass
     with param "+SP64" ... but maybe that's my puter

  That's a pretty large max_trace_level. Try lowering it (perhaps to something
like 30) and/or using adc_bailout.

nope ... no way ...

even 64 gave me a lot visible black dots in some of the bubbles ...

Of course, only in some of the preview passes(I stopped then),but I don't
think
the multi-sampling by focal-blur would have helped ...
