Why is the movement of the cursor and windows in windows not smooth (even jerky), but the video on YouTube at 60Hz with the same cursor and windows goes smoothly and without delay?

Good afternoon.

I have a simple monitor [email protected], an old NVidia GTX660.
I somehow watch a video on YouTube with 1080p60 quality and understand that my video card and my monitor are able to honestly show their 60Hz and 60fps video, where everything is smooth and fast.
And here's the paradox: on the video I get smoothness, but in windows itself, the cursor and windows move with a noticeably lower drawing quality or something. That is, leading the cursor across the screen, I see its movement in jerks.
Is there any way to convince windows and drivers to run at high quality at all honest 60 fps?

UPDATE:
The jerks that I write about in the question are what I call the usual normal behavior of the interface. This is not a brake at all, I describe the usual operation of the interface on many computers, on every one that I have seen in recent years (these are hundreds of PCs with i7 / SSD / tons of memory / modern chips).
It's just that once I happened to work on one laptop, where there was an incredibly fast drawing of the interface - the cursor, windows, everything moved instantly. It can be compared to the feeling when you switch from watching a video at 30 frames per second to 60 frames per second.
And since this quality is available when watching a video, it means that windows with drivers can somehow be configured for the same high quality of interface rendering. Especially since I saw how it was done.
Maybe, of course, the matter is in the HDMI / DP bandwidth, maybe in the hertz of the monitor. But the fact is that on the same HDMI, a simple 60Hz monitor, the same video card and drivers, I get high quality 60 frames per second in a YouTube video.

Your video is running fine.
And rendering the desktop and interacting with the user is completely different and depends on something else.
Mouse jerks are not due to the frequency of the video, but to banal delays.
Maybe there is not enough memory, maybe the disk can not cope, maybe the mouse is worthless or the software is some kind of curve.

Check HDD or SSD.
