A lot of new features, some of them good, like materials, structured directories, and strand-based hair (I bought some geat hair from RDNA). Some which don't work, like collisions. Many that are worthless, like dynamic cloth (simulation too slow), content room (I already have a web browser), face room (P5 only), P5 "Lost-in-Space" characters. And a new problem -- performance. CL should have solved the clothing poke-through problem and implemented hardware rendering first. I thought P5 was OK, but now I feel cheated since I heard about DAZ Studio. I think CL rushed P5 because of their new competition.
