When looking through the binoculars (or a scope in your hands) the mouse movement feels very 'floaty', it feels as if some kind of inertia from the character has also applied to this view and it feels pretty bad compared to 1.18.

Tested with -
Binoculars
Hunting Scope (in hand)
RVN Sights (in hand)

The scopes feel much better when attached to a weapon.
