So I had a problem with game reseting Audio/Video settings each time the game is started and not honoring the settings I've previously made.
And found the solution that you can maybe implement:
%AppData%\Local\R5\Saved\Config\Windows\GameUserSettings.ini
Needs to have a Read-Only attribute for it to stay how it was previously configured when the game is starting.
So maybe you can implement in the future that the game disables read-only when changing settings and re-applies it when done so they will persist between the gaming sessions.
