Btw, I like to point out that I understand
exactly what you mean with that. It's the main reason why I can't deal with 30FPS gaming. It does look like judder, but it's not. The only way to hide this is through a high amount of motion blur.
The first video shows display ghosting when you play it frame by frame. You can do that in the YouTube player by pausing the video and pressing the "." key on your keyboard. Press it repeatedly to go through the video frame by frame. It's probably a VA panel TV, and those have larger amounts of ghosting compared to gaming monitors. This ghosting can actually hide some of the 30FPS ugliness. There is also a chance that this is not display ghosting, but the game does it on purpose to make 30FPS look better. But I think that's unlikely. It's probably the display.
The second video looks perfectly clear. There is no judder actually. That's how 30FPS looks like when you have a crystal clear image without ghosting and without the game using motion blur. The clearer the display is during motion (and a gaming monitor is always much clearer than a TV), the more obvious the stutter and almost "flicker" like nature of 30FPS becomes. Also, playing a mouse instead of a console controller can make it worse, because faster motion exaggerates the issue further compared to smoother and slower motion with a controller.
If you do indeed get judder in the games you play on your PC, you should tweak your RTSS cap slightly. Instead of 60FPS, use 59.9 and see if that helps. For 1/2 vsync, instead of 30FPS, use 29.9FPS. This makes sure that the RTSS limiter is actually getting triggered for each frame.
Also, since you have a 144Hz display, there's a nice trick you can do here. Play the game at 144Hz (set "Highest available" in the "Preferred refresh rate" setting in the nvidia panel's "3D Settings" section) and then use Inspector to set 1/4 vsync which gives 36FPS, or 1/3 vsync, which gives 48FPS.
Finally, for Skyrim in particular (and the other Bethesda RPGs, like Fallout 4), you really need to disable the game's vsync in the ini file, and force vsync in the nvidia panel. The Bethesda engine has severe issues with its own vsync implementation and on many systems it has extreme levels of judder.

I've enable the frame counter like that you can see the framerate jumping to 61/62 for no reason, even with RTSS or with the nvidia profile inspector framerate lock, or without frame lock at all. Also i have enabled Vsync through nvidia profile inspector and i've locked the framerate to 60 with RTSS. I play in fullscreen.

Its definitely not smooth.
OK, there
is definitely judder in that video (going through it frame by frame makes it obvious, since some frames are duplicate.) Try and see if a 59.9FPS limit helps. Or perhaps 120Hz with 1/2 vsync and a 59.9FPS limit.
(As a side note, 120Hz or 144Hz with a 1/x vsync setting is usually better overall, as it gives lower input lag in combination with an appropriate RTSS cap. But that's another story entirely.
