I simply meant that on MY machine, with full tracking on, posing in P5 is 10 times slower than P4,(I'll even back up a bit and say its only 5 times slower). Even when rendering in P5 with all the P4 defaults in place it is still about 3 time slower. Your personal experience may vary. The only thing that keeps P5 on my machine is the added complexity. Otherwise it would just be a slower P4. I want to use the darn dynamic clothing and wind effects for my animations so bad I can taste it !
