Generating previews uses only one core?

Hi, I am using Capture One 22 and recently decided to upgrade my system to new Ryzen 7950x.

I was eager to know how much fater my photos will be processed, and started with import.
When I selected photos from one of my timelapses (3381 photo) and clicked import, I noticed that during preview generation - only one single core was used.

Is there a way to let Capture One know I have more than one core for this? =)
