The small patcher removes black bars from the game at all wide resolutions.
Keep in mind that some of the textures simply do not have enough width to fill the screen, and the menu UI will become cropped the wider it gets from 21:9, although the game appears to be playable even at 48:9.

Tested the latest GOG version at 2560x1080, 3440x1440, 3840x1080 and 5760x1080.

The patchers and trainer remove pillarboxing from the game, resulting in more horizontal FOV.
Some of the in-game images and cutscenes do not appear to be wide enough to fully fill the screen, but the main cutscenes, menu and gameplay become free of black bars.
Use one of the patchers to modify \ChildrenOfMorta_Data\Managed\Assembly-CSharp.dll within the game folder. For the Game Pass version, use the included trainer at 21:9 - the password for the 7zip archive is pcgw. Tested briefly at 21:9, 32:9 and 48:9 in the latest GOG and Game Pass versions. Resolutions wider than 21:9 were affected by severe terrain visibility issues.
