Thanks for the pointers, my system is water cooled and only every reaches the very low seventies when I have a long render running.  In this case some of the processors are not in use as the CPU is only running at around 25%.  Poser itself is on an 500G SSD with 419g spare.  None of the other problems seem to have an issue only Poser. 

 

 

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.
