How many CPU cores will Poser 13 recognize and use?

I am not sure on the maximum but it runs the 32 cores that I have with no issues.

thank you. 

I have a 24 core processor running Windows 11; Poser 13 recognizes 48 threads. Not sure how many it actually uses for CPU rendering:

I have a 24 core processor running Windows 11; Poser 13 recognizes 48 threads. Not sure how many it actually uses for CPU rendering:

Set up like that it should use all 48 threads with a CPU render.  In Poser 12 you could confirm by seeing the number of blue edge boxes at render time.  Not an option Progressive Refinement which seems to be the recommendation in Poser 13 but Windows Performance Monitor shows all 32 of mine in use during a render.

I'm fairly certain the limit for Poser 12 was 32 cores 64 threads. With in creasing cpu cores, I was expecting P13 to use more.

Poser 13 auto-recognised 12, but together my PC's 12 CPUs have 24 threads. I then manually set the 24 threads in Settings, and this setting was retained on future launches of the software. With that kind of power in a PC, many Firefly / Sketch render presets will likely also need their "buckets" setting tweaked up - from the default 32, to 128 or higher, for a much faster render.

my findings with Firefly were optimal at 128 bucket size then it starts going down after that.

How to make poser 13 render fast using cpu only? found out poser 11 render more fast.  I use dual XEON processor 20 core each total 80 threads. Poser 13  recognizes 40 threads only. 

I feel inadequate with my petite collection of 18 cores (dual Xeon) :(

My network-render PC deploys ~15½ of its 16 Ryzen_7 cores but, hey, complete 'Box' was cheaper than upgrading either of this now-ageing CAD_Tower's twin GPU cards...

I liked the blue boxes for each thread / card in poser 12, do you know why they disappeared in poser 13 ?

I think the main reason is that Poser 13 works differently, in previous versions each thread had it's own bucket to deal with so it there were 16 threads there were 16 blue squares.  In poser 13 all threads work on the same bucket at a time.  You can get the blue box back as I have seen it when I launched Poser 12 scenes in Poser 13 but you will only see one blue box at a time.

You can get the box back if you don't render in progressive mode.  However, all cores will be put to work on the same box.  This is to prevent one core from being left along to finish a complex section while the rest of the cores sit idle.  But given that there does not appear to be any change in the quality of the render between the two modes and that with progressive you can spot a flaw early on and cancel and fix rather than wait till the image is 3/4 finished to see the flaw, that should save time.

I too liked the little blue boxes, not sure why but I have soon changed to, and happy with, progressive mode for all the reason you have given.  You can see some mistakes very early on, usually after only a few samples.  Lighting takes longer but then I tend to do a small area render to check that before rendering the whole scene.
