Question Low CPU usage during games

[kraylbak]

My PC, consists of an i9-13900K, an RTX 4090, 64 GBs of RAM and a 1000W PSU.

Everytime i play games like Hogwarts Legacy (4K Ultra RT), my GPU hits near 100% usage, while my CPU remains at just 1-2%.

Is that normal?

Am i doing something wrong?

Reduce quality and resolution, if CPU usage and FPS go up then it's normal.
4k is demanding and ray tracing on top of that many times more so.

OK, thanks for the reply.

I was just worried that my CPU might be underutilised for some reason.

13900k has 32 processing threads.
I understand the game to be largely single threaded which would give those results.
Activate task manager and set the cpu graph to show logical threads.
