Hi, just installed Poser 13 on my system and it runs smooth so far.
First renders of the factory scene came out fast as lightning on my Nvidia GTX 1650, so everyone with a newer GPU should get much faster renders even in higher settings.
I will run some tests with older scenes and check all the new features listed in the first post here.

Congratulation to the release of Poser 13 to all the people who were involved.
Well done!
