I am still using Poser 11.1 and there was not any slowdown I guess it is an issue that happen when Bondware was toying around and making there changes to it, integrating renderosity store to the libraries. the moment Bondware got hands on poser they ruined allot of features not to mention the Desaster with Pyton support that you need a third Party app to keep em running . I still have every Poser running since release and they all work like a charm with exception of the Bondware versions ! It is where the Problems really start.
