If that doesn't helps, create a DxDiag in text file format and post it with your next reply. You can do that with the "Choose file" button at the bottom right corner of the reply window.
Sadly I have tried that multiple times, what I have discovered is that it affects All Cinematics, there is a desync between dialogue audio and the cinematics, while the sound effect cinematics are perfectly lined up, and, all cinematics are incredibly slow, it was hardly noticeable in the first game's videos, but as there are many more in the second game they are Much more noticeable than they should probably be, like trying to watch a 4k bluray through a 460p monitor, except my monitor is able to utilize 144hz.
Your Graphic driver is outdated.
Seeing your description of the problem I would suggest a clean re-installation of the driver.
Furthermore, it is true that your SAMSUNG LC24RG50 can utilize 144Hz, but it currently runs at only 60Hz, you should recheck the settings after you installed the driver.
Is your 580 an eGPU? Because there are at least a dozen eGPU users reporting the exact same behaviour
the problem is the playback of the BIK movies through bink2w64.dll. I tried an older version but no difference, so It must be a parameter passed to the DLL.
When I play the BIK movies directly with RADGameTools, there is no stutter whatsoever, so the movies are fine.
