Nuendo 10.3.0 - CPU frequency drop down to 1Ghz

Post by aas »

I evaluate (before I buy) Nuendo 10.3 trial.

I was working on a big project when, suddenly, the CPU frequency decreased and the project cannot play anymore on my Macbook Pro 2018. I cannot share my project for obvious reasons, so I decided to investigate with the Nuendo 8 demo project Fractured.

I performed some test:
  • first screenshots are references of my Macbook Pro idle
  • second screenshots, I ran my computer 100% with Intel Power Gadget / Test / All Thread Frequency
  • third screenshots are with open project and Nuendo waiting to play
  • fourth screenshots are Nuendo playing causing the big cpu decrease !

Intel Power Gadget screenshots:

Activity Monitor screenshots:

Macs Fan Control screenshots:

What I really don’t understand is the Nuendo project is only stressing my computer at maximum 35% before the big frequency drop down to 1Ghz.
On the other hand, I’m able to run my computer at 100% forever with Intel Power Gadget at nominal frequency 2.9GHz as expected.

I wonder if someone has/have the same experience ?
Are you able to play this demo project on a computer similar to my Macbook Pro 2018 - 2.9 GHz Intel Core i9 - Radeon Pro 560X 4 Go ?
Is there anything I can do to fix the cpu frequency decrease ?
