"Physical Crouching" from Boneworks was basically circumcised in BoneLab and replaced with a new system of how things work, you can sit down in real life and stay standing up in game but this murdered actually y'know, taking cover physically too, and that means with the damn near removal of Physical Crouching means that it automatically determines you height too, there is no manual setting like in Boneworks either and that automatic adjusting is pretty awful at it's job too, hence why you're always tip-toeing around, it's a global game issue that fails to be the "quality of life feature" it was trying to be on every platform this game is on, and I believe that godawful feature is the main reason why you can sometimes break the sound barrier and go flying after pulling yourself up a ledge too. (That is a known bug.) I hope this was informative.
