I don't think 144Hz is a "bug" but rather the physics engine being tied to 60Hz, so going above 60FPS can start to introduce weird issues.
Fallout 4 had the same problem, and I don't think that was changed so I would guess not unless someone can confirm this.
*This is probably NOT ideal advice, but unless someone else knows better then I would suggest forcing on "Half Adaptive VSYNC" through the NVidia Control Panel (or RadeonPro set to "Dynamic Half VSYNC"). This will force to half 144Hz or 72FPS. That would likely eliminate most of any physics issues (if they still exist) by being close to 60Hz but still allow VSYNC to avoid screen tear.
You also need to ensure you can MAINTAIN the frame rate to avoid issues so tweak the settings appropriate. I see no major issues going below 60FPS other than the typical sluggishness.
Note that:
VSYNC ON - eliminates screen tear, but can add STUTTERING if you fall below the 60FPS target (for 60Hz refresh)
Other:
If you have GSYNC, FREESYNC, or don't mind screen tear (varies by the game) then I suggest setting a cap of 60FPS. Google for info on that if you don't have a 60Hz monitor.
I hope that helps.
Update:
SKYRIM isn't a fast game. So 60FPS is fine IMO. Again, whatever you end up going with make sure you can MAINTAIN it, and ideally don't have screen tearing.
Let me put forward THREE scenarios which apply to different monitors:
1) 60Hz monitor
- VSYNC, or Adaptive VSYNC ON
- and maintain 60FPS most of the time
2) 144Hz (normal, synchronous monitor)
- Half Adaptive VSYNC?
- and maintain 72FPS most of the time
3) 144Hz+ GSYNC or FREESYNC panel
- cap game to 60FPS (not sure how as I don't own either. NVidia is GSync, and AMD is for Freesync)
- and maintain 60FPS most of the time
