3d mouse is no longer smooth since last update

I cannot duplicate this. When I rotate a model on my mid 2012 MacBook Pro with a 3DConnexion mouse, the screen redraws at about 40 fps.

You didn’t mention anything about your environment. Please see this post which will tell you how to tell us your hardware and software environment.

Also, there have been a lot of releases recently, so latest version and previous version are pretty ambiguous. What was the version number (YYYY-MM-DD) that worked for you? What is the version number that now is not working?
