If you’re having resolution issues, or the game has bad settings, this is how to alter or remove the game’s config files manually.
On WINDOWS, the config files are found in SteamLibrary\steamapps\common\Objects in Space\ObjectsInSpace
On MAC, the config files are found in your Documents folder, under ObjectsInSpace.
The .cfg file, save games, latest log file and any crash dumps are kept there.
If you remove this config file the game will return to default configuration & settings next time you load it. You can also alter settings here manually, including resolutions that may not be detected by your monitor.
