Do you get the warning message when loading the pz3 with reposing enabled? It says something along the lines of "this will use alot of resources. Do you want to turn it off?"

You need to answer "No" to this question in order for Vue to enable reposing. If the question does not pop up, you have it disabled at some point by checking "do not ask again" and it is stuck at "yes". You need to go into options and "restore messages".

However, I agree, reposing overall works pretty poorly (very sluggish) when compared to directly posing collada imported skeletons (from DAZ Studio). The reposing is sort of useable with lots of ram (12 Gb or more) for small adjustments.
