The only difference I've noticed is I don't have to make the keyframes yellow to prevent joints from spinning around  when I add keyframes.  I don't know if that makes sense to you the way I worded it.  As for rendering animations, richard is correct.  The main benefit of this is that it is now possible to also render depth maps for the animation etc, and apply postfx, which I don't think you could before. 

you can use the fitting room.  bring your posed figure as goal.  don't zero.  bring your conformed clothing as object. don't zero pose.  Don't run simulation just his spawn prop.  You now have a dynamic copy of your conformed clothing.  parent the new object to your figure's hip.  in cloth room constrain any parts of the clothing you want to act as confromed and create a dynamic group for any part you want to simulate.

set up your animation in daz.  Export the animation as a bvh file.  import the bvh file to your figure in poser.

My method has been to color the background green and remove it as i would a green screen in the other programs.  More options in movie rendering would be helpful.  An animated depth map would be useful.
