I believe that the Mac version of Bryce 5 is optimised for G4 Altivec processors (dual as well!!) and OSX! - that should be a great combination! - I must admit, at least 'some' more complex modelling tools would be sensible by now, as to the render engine, sure please speed it up, but dont lose its quality!! - soft shadows, plants and built in motion effects would be cool also!
