Yes -- default options, basically.  I wasn't feeling too adventurous when I did
that quick test. :)

Oh, alright.  So you're saying that with preview off that scene would have
probably rendered as fast as my Wintel rendered it?  Sounds plausible to me.

Heh, I still have to try 3.5.1...

Bananamark...hehe, I like that. ;)

I'll have to run benchmark.pov on both of my systems to see which one is truly
a better POV-platform (with preview off, of course!).  I honestly never thought
that preview being on made that much of a difference!
