Thank you, and one last question to bother you with, since I am planning to write a short essay on this one
So would you agree that from a Mouse Movement(E.g. measured in cm ) point of view, as long as the sensitivity/DPI & resolution all remain the same, lowering(or raising) the FOV doesn't actually change your mouse movement( amount of cm moved) required to switch aiming between the same two targets.
But however lowering the FOV does mess up your spatial awareness since our eyes perceive monitor distance(2D) instead of degrees turned(3D), (which in this case, remains the same? or does it?)
Meaning your hand's muscle memory to move a certain distance between the same two targets can remain perfectly accurate(E.g. I can move my mouse 3 cm to the right perfectly even after lowering Fov), but after lowering the FOV, targets now has a shorter monitor distance between them(and appear larger), since they now appear to be closer to each other, one can wrongly overestimate the corresponding distance to move his mouse, since our eyes are not accustomed to the new 3D space/messing up our hand-eye coordination instead.
