Question / Help ntoskrnl .exe

[B31]

So whenever OBS is open, I can see in the task manager that "System" is using around 20-30% of my CPU. The path leads to "ntoskrnl" under "system32".

Does anyone know how to fix this?

Unplug or turn off your webcam. Does CPU usage go down? If yes, reduce webcam resolution down to maybe 640x480.

Other places that CPU usage might be used by: having 2 GPU (graphics processing unit). if OBS-Studio is rendering on NVidia, and your display is on intel graphics, Some CPU usage is used to transfer data from one GPU to another. Does turning off preview reduce CPU usage?
