Title: daily v14 build ignores thread settings (uses 100% cpu despite IPR settings )
Post by: Stefan-L on 2025-08-23, 17:45:45

Hi
v14 daily again ignores the corona threading settings in preferecnes (was same in eary v13 dailies)

i set it to 18 threads on a 56 core machine, but ipr uses 100%.
the PC  is absolute unresposive dur8ing IPR usw

this is on a dual xeon.

i wil have to revert as atm this build is unusable that way, hope for a soon fix
thanks!

I am observing the same behavior here on V13 HF1 and the 05.08 V14 DailyPreview. Could you please compare the graphs showing CPU usage in the Windows Task Manager or some 3rd party app (I used Process Explorer) when running IR in V13 and V14? If you are getting different results, please let us know here.

as said i get very different results, i did chekc in task manager.

i have set ipr to use only 60& of the cores. in v23 this is reflected in the task managers cpu usage.
in v14 i get 100% usage

BTW, why use the 14 Preview, since that build is already out as the final build 13 Hotfix 1? The only published preview for C4D is older than the official release.
