Speaking as an animator, P7 is awful, at least so far.  Clothes, hair, jaw-teeth parts all go flying off and out of the figure (i.e., parenting loss).  I have a high end machine with a high end nvidia graphics card and the latest drivers so it is not my machine.  Sorry to sully the thread with a negative review, but ... I've gone back to P6 until SR1 comes out... though if I need a quick still P7 does render faster.  cheers...
