"Change the amount of Max cached render to 1. You don't need all those cached renders."

Great thread and good advice however the above might be a personal choice.  I like the saved renders so that I can see the difference any changes I may have done to the scene are reflected in the renders.

For newcomers you can do this in the renders screen, use the arrows in the bottom left corner the first to select a saved render from the list when you click on the arrow. Use the second arrow to select a different render.  Now by using the slider you can do a wipe from one to another.  This can be very useful to see changes in shadows and other details.

 

 

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.
