I replayed Alien Isolation these couple of days. The converge was way to large default, I guess its because i'm on a HMD and the FOV makes it differ from normal 3D vision users on a monitor. Anyway, why is the perceived scale affected by the converge setting? If I use a converge level that gives nice 3D feelign the in game characters feels small and dollish, if I look down the distance to feet feels wrong. If I use a convergence that do give the correct scale the world almost feels flat.

It's to do with the size of the image on your retina vs the direction you are looking at.
All these things might appear to be the same size to your eyes depending on how far away they are:
[code]
\<------------->/ <-- goliath
\ /
\ /
\<------->/ <-- people
\ /
\ /
\<->/ <-- toys
\ /
o <-- you
[/code]
So, to distinguish their size your brain uses the direction your eyes were pointing - if you are cross-eyed you are looking at a toy, if you are looking at something a few meters away you are looking at a normal sized person, if you are looking out towards infinity you clearly in for a boss battle ;-)
Since the convergence control allows you to adjust the direction of your gaze without changing the size of the image on your retina it affects the perceived size of object on the screen.
You can see the same effect if you find something like a brick wall and go cross-eyed to merge the image of adjacent bricks together - the bricks appear to get smaller. If you look beyond the wall and merge adjacent bricks together in your vision they appear to get larger.
