I agree with the comments already made in this thread.  Last year I built a new system to replace an old dual core PC.  With Poser Pro 2010 and Windows 7 available I installed this on the new system that had a quad core CPU with hyper-threading which gives a virtual 8 threads.  Running the 64bit allowed me to take the memory from 4Gig to 12.

The extra memory allowed me to render more complex scenes but the big plus for me was the speed, renders that had taken hours before were now completing in minutes rather than hours.

Of couse, as is the nature of things, I now have some renders that take hours but the scenes are more complex and results way above my earlier efforts.  I did try one such scene of my old system to see how long it would take, expecting it to take days, but the system would crash (probably due to lack on memory) very early during the render.

 

 

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.
