LOL this is what kills me about Reality Lux users ( Exluding most of the ones "here" LOL)  we can wait 4 days to a month to finalize a large scene rendered but god forbid if your scene takes 5 minutes to load in Studio. This is why I have no issues staying with 4.0 if 4.5 dont play nice with my machine.. As a lux user you gain as you say not using the utility transfer tool and maybe save some time on loading / saving a scene. On the plus side I read on the DS forum that geometry shell does work well in LUX even though I have no clue what it does... Guess I can youtube the new features..
