I think windows has a feature built in on some adaptive refresh rate displays to dynamically shift the frame rate down (to 30, on my screen) or up to the cap, depending on what’s actually happening.

I remember playing with it a bit, and it would dynamically change to a high refresh rate as you moved the mouse, and then drop down as soon as the mouse cursor stopped moving.

I had issues with it sometimes being lower refresh rate even when there was motion on screen, so the frame rate swings were unfortunately noticeable. Motion would get smoother for all content whenever the mouse moved.

1hz is drastically fewer refreshes. I hope they have the “is this content static” measurement actually worked out to a degree where it’s not noticeable.
