I guess I shouldn't have changed anything in the xdb files of your mod and MaksSP's mod. Oh well, if that's the case, I'll try to tweak it again tomorrow, but for now, I don't want to overthink it, and I also want to sleep.
Thank you for your attention.
As far as I remember, you can stretch it up to a maximum of 1364x768 so that the game doesn't crash, but you can compress it from full to 1366x768.
