Asside from the confirmation, there needs to be a VERY usable way to switch resolutions EVEN if you fuck it up royally. I ran into this in Homeworld 2 where a bad resolution is
1) not undoable
2) if made, the only way to clear is to completely nuke ALL non-vanilla data from the installation directory since I have no idea where resolutions are stored.
Solution. Make resolution switching app external to game just incase shit happens.
