I notice that this game deletes the Engine.ini if it exists in %LOCALAPPDATA%\Voyage\Saved\Config\Windows. This hampers players ability to get better performance as we cant alter how the game renders things. I know you dont like people editing the game, but this isnt modding. This is just config changes. It will make it alot easier for people to play the game, and as far as I know, it cant cause issues without an outright CTD (like using the settings to generate the shader files, which will crash the game), so you shouldnt see any issues from people using this.
