How should I properly configure recording options for 4K using a capture card?

I have a dual-PC setup, both equipped with DELL G3223Q monitors (3840x2160, 4K, 144Hz). The second PC features an AVerMedia Live Gamer 4K (GC573) to capture video from the main PC.

As far as I know, the GC573 supports up to 4K 60Hz capture, so I configured OBS as following:

(I've set a custom resolution and FPS because, by default, it limits the resolution to 1920x1080 instead of 4K.)

However, the final footage has a lot of stuttering.


Any advice, please?
