Talos Principle 2 - everything stutters just like GUI elements?

[2mg]

So with NVCPL Vsync ON, ingame OFF + Unlimited FPS, everything stutters exactly like GUI elements stutter - https://imgur.com/a/HdJQg7s (ignore the FPS counter, recording tanks FPS, issue happens at high FPS when not recording).

And even when looking at scenes with high internal FPS, the mouse is still floaty.

This can be replicated in AW2 if you use an external FPS limiter, so probably NVCPL Vsync ON doesn't play nicely with Fgen here for some reason (puts an FPS limiter?), because in AW2 it's buttery smooth.
I also tested Fgen OFF and NVCPL Vsync ON and lowered ingame settings, it's also buttery smooth.
