Asterigos: Curse of the Stars on release has an issue with how the ultrawide feature is implemented, in short the field of view is incorrectly sized. This gives the effect of reducing your vertical vision and always looks too 'zoomed in.'

This is especially annoying when paired with the lock on mechanic in combat, as enemies (mostly bosses) can move out of view as you're locked on. This zooms the camera towards the ground in front of you, placing the enemy you've locked onto, out of frame.

Here you can just add a few lines into an ini. file and remedy the issue. Ezy Pzy.
This may get patched, as this is written as the game has just released. Also to reiterate, this is only for ultrawide users.
