USAGE OF CPU

Hi guys,
I have a major problem. I have a CPU i7 11700K, which is pretty much a solid CPU for AE and it's needs. I also have 32GB of Ram.
However, I have a problem with CPU usage. While I'm working on a project, and want to see a live preview of it, by pressing the spacebar, it's really slow and CPU usage is averaging 20%. However, when I stop everything and let the AE do it's automatic rendering which is happening after a couple of seconds, CPU usage is 100% and the green line/live preview is being done rapidly.

What is the problem? Why is it that when I need the CPU to work and engage 100% while live previewing and working, it only averages 20% of Usage, and while I'm not doing anything, it goes 100% that entire time. I really need your help and advice for this since it's driving me crazy!!

You need to study up on multiframe rendering and trhed associated background caching. That's all there is to it. Please do read the online help.

    Can you please provide me with some of the materials that I need to read?

    I have a project lagging on a simple rectangle table with text, which is by the way, still and not moving, and the CPU usage is 18% and live preview is lagging. That doesn't seem logical to me
