hehe 
danke.
yeah, theres also the ability to display each level independently with isolate select, but it doesnt really speed up anything, especially when your working with blend shapes as the transforms still haveto be made.
i mean were running nowdays 1ghz + machines and i'm still having the same response time from my (well now subd models as i don't ever want to go back to mesh smooth) models and blendshape sliders as i did when I was running a p200? The really great thing about todays hardware is you can really do some spectacular realtime deformations on reasonably high poly count models, i'd just love to be able to use it as such with subds as its really a matter of adding one check box to the ui.
to haveto use a wrap deformer on a subd model is just wrong on so many levels.
