Hello everyone,
First of all apology for posting here about something that might be a HW related issue. Last week I've upgraded to i9 12900KF and I'm observing some strange behaviour. I've stumbled upon a thread on the Intel forums that describes it perfectly:
https://community.intel.com/t5/Proce...U/td-p/1364397
This CPU features something called CPU parking (core parking). Obviously it is designed to disable some of the cores when not needed and enables it when they are. This keeps the power consumption low and keeps the CPU cool.
Running Vray or Corona benchmark utilities, wakes and uses all of the cores. Apperantly Phoenix FD in 3ds max does so as well:

However, rendering with Vray in 3ds MAX only uses few ot the cores and the rest are idle (parked):

Win 10 Power settings are set to "Ultimate perfotrmance". Worth mentioning that I have the PC pluged into an UPS. Tried to plug it directly into the power grid but this doesn't seem to change anything. Might be a 3ds MAX related issue. Might be a problem with the HW. I know it is a long shot posting here, but I wanted to check if anyone had the same issues, before heading to Intel forums.
Thanks
P.S. It's max 2022.3 and Vray 5.20.23 Build 00002
