I think most of my "Dynamic hair looks worse" comes from the fact that most of what I see from it looks like slightly styled wires sticking out of a head with bald spots in the examples I have seen but I admit I have never used the hair room because of that. And the few times I have used it on stuff that came with it renders VERY slowly.

As for dynamic clothes, most times the stuff I have used ends up torn, in pieces and on the floor but sometimes can produce decent results. I do wish there was a way to smooth the bends sometimes because they can look rather crinkly (when I have gotten them to work) but it annoying since it is hours and hours to see if something will look like garbage or what.
