I don't experience any such lag spikes even when I have a lot running. Are you using a Macbook Air?

I get this on my Mac Studio when I do anything CPU-intensive, the UI becomes jittery. macOS on M CPUs seems to be particularly sensitive to this because I can push a Ryzen much harder and not notice anything in Windows.

Windows XP used to have that issue until they released some patch that prioritized UI when CPU was under stress. Linux had the same issue some time ago as well. I guess Apple will need to do something similar...
