The game feels more immersive and provides information with a larger aspect ratio, e.g.: 21:9, 32:9
But given the nature of this game it is impossible to play on full screen with one character.
It would be nice if players can customize the resolution in windowed mode.
E,g,: Playing on a 4k monitor,
Main Character: 3840 x 1620, 21:9
Alts: 16:9 small windows
PS: I know there is a already existing suggestion proposing the support of 4k, but not really detailed.
PS2: It is technically possible and feasible.
