(perhaps something to do with observers)
I was writing a response having this thought, but I deleted it, when you posted yours
. I'm inclined to think the same... maybe there are plugins that have observers active for watching the cursor position, or chanve view, edit/create/delete geometry... and maybe that ones are using so much CPU
I wasn't doing anything, only opened the model. It was a model that had to be cleaned. After I reworked the geometry it went back to normal.
(because turning it off might not work every time, as there is LAN wake up and other stuff that trigger BIOS to send signals to CPU)

- i have my excuse: it was late night.




Or you are worried about materials? Maxwell "knows" sss for dingle faced geometry, so you can benefit of that for leafs.
