I don’t know, Bethesda’s games have always been iffy when it comes to FPS. Skyrim for example breaks if you mod it to have over 60 fps if I remember correctly. Even on Fallout 76 movement speed was kinda tied to the FPS so players looking at the ground (so that less things render thus increasing FPS) would run faster than others.
I honestly wouldn’t be surprised if they cap it to 60 FPS on PC as well.
I’m sure soon enough people are going to develop some “get to the point” extension that automatically deletes all the unnecessarily verbose sentences AI writes.
