Linux Mint 20.3 - Mixx 2.4 alpha 1245
Hello, my fastest Laptop shows in the skin a visiable cpu usage of about 30-40%
If i see in the system info of linux mint, the average cpu usage of all 8 processors about 5-10%
Maybe is a visible issue becaus on this laptop i use the retina skaling 125%
Maybe Maybe I'm just imagining it. I thought i report it, becaus my 10d years old laptops work visible with less cpu usage - same linux, same standard installation.
Here is my hardware:

The CPU meter is actually the "audio latency usage" and only partially related to the er overall CPU load. The audio buffer can only processed by a single core that's why the CPU frequency is more important than the number of cores. By default, we have no control what else this core has to do. That's why we normalize the value to 25 %, for some headroom. This was tested on the worst case machine, a single core CPU with hyperthreading enabled, to provide a certain reliability of the meter.
On your 8 core CPU, this is probably too pessimistic but still valid.
By the way, we have a branch where you can reserve a single CPU for audio.
