It would be interesting to see the performance comparisons if everyone rendered the same file.  Anyone wanna pick one that was perhaps included with Bryce 6?  I'm still working on getting mine installed (am upgrading from B5 to B5.5 to B6), so don't yet know what all was included in the package and the bonus content.

I dare you, while there is still time, to have a magnificent obsession. --William Danforth
