You can just quit the App, the power management is done by the kext independent of the App.
Indeed, why kept the windows open if you don’t want to see the graph? I believe all Cocoa applications will stop rendering when minimized to background, it could be the timer task that is running that forcing CALayer to update. I will do more profiling soon, but I’ve never saw the application use more than 5%. And I am as well using a Ryzen 3900
I'm also seeing 15-20% CPU usage in the Activity Monitor
edit Looks like it also creates quite some load (15-20%) on the WindowServer process.

The load is directly attributed to the drawing routines. Not that the visualization of the graphs is a bad thing, it's just a bit resource intensive on macOS Catalina 15.5.5 with a 5700XT running a 4K display.
Running the distributed application, AMD Power Gadget is currently using 15.7% CPU utilization. Any time the displayed graphs displays a large variance in values, CPU utilization increases to 18%+.
In ViewController.swift, commenting out lines 113, 115, 120 and 121, CPU utilization for the app drops to 0.1%.
Enabling just the temperature graph, CPU utilization sits at 5.5%, about 1/3 of the recorded usage.
The information you have provided is not helpful at all. Yes of course directly disabling some functionality in source code will reduce CPU usage. Plus 15% is very much acceptable. Beware that activity monitor uses Unix style display in which that 15% is not of your whole system, but a single logical thread. Though it is always good to optimize and reduce resources usage. It would be helpful if you directly open up a pull request or provide a profiling of the current drawing program.
I went back to version 0.6.1 and re-tested. There was virtually no CPU load by the App back then. I assume the new fluid drawing added afterwards is the source of it.
And the differences are not neglectable. The new implementation seems to results in 10-15 Watt increased power usage while idle with temperature up by about 2 degrees compared to the old implementation.
@trulyspinach. Hmmm. And here I thought I clearly demonstrated chart drawing is the source of the CPU usage. Showing with drawing enabled (15-18%)- disabled(0.5%), and with one chart enabled out of 3 (5% or 33% of the load) ~ VS the overall low percentage on your machine with a 3900x.
@aluveitie - Good catch on increased power consumption and temp increase due to the drawing routine.
I noticed the increased power usage too while idle as @aluveitie has mentioned.
