Title: Corona don't uses all the cores
Post by: pictura on 2021-04-12, 14:20:50

Hi.
I just installed daily build  "Corona Renderer 7 for Cinema 4D (Daily Build 2021-03-31)". I used corona 7 previous daily build.
I hoped so it will be no more dissapearing geometry with displacement in live view rendering.
But i noticed i render much much slower. When I open a task manager I see corona don't use all cores.

My spec is:
WIN 10 PRO64 bit.
Version 20HC

Gear
AMD Ryzen Threadripper 3970X
32-Core Processor    3.69 GHz
RAM 128 GB
NVIDIA GeForce RTX 3060 Ti

Hello,

thank you for reporting. We are already aware of this issue and are working on a fix.
Sorry to cause you trouble, in the meantime, I would recommend reverting back to 17/02/2021 build if on a deadline.

Thanks,
Jan

Admittedly I don't use daily's and C4D but it happened to me few times as well. It occurs in specific old scenes saved with v1.5. Corona uses precisely 50% of the cores and still don't know why, strange behavior anyway.
