Why is Fallout 4 capped at 120 fps?

It’s a limit of the creation engine, a lot of stuff is tied to the monitors refresh rate. There’s two possible limits with 60 or 120 referred to as FPS clamps in an ini configuration fille.

There is a mod which works around this, allowing for more normal fps control
