I purchased a Spacenavigator about a year ago, I would love the Spacemouse but could not justify the cost as a hobbist.  The Navigator is superb although it can be sensitive at first the control is so easy and natural.  Not only that, click a button and you now have the same control over a character just by selecting the body part.  I would find Poser so frustrating if I lost the use of the Navigator.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
