Smoothing can be controlled:
Goto General Preferences and set the Smoothing angle at 180.

Smoothing in Poser has seen very good evolutions over time and does quite a good job.

Secondly:
In every objects parameters palette you can control smoothing also from 80 default to 180.

Here you can also select smoothing OFF if you do not want it on some of the things in your scene.
