With other app, resolution selection window works.
Do you disable it? If yes, why? Now i made 2 batch file, one for 720p, one for 1080p
No I haven't disabled it, honestly I don't know why it doesn't work. Tried it a few times early on and gave up. Yes it's pretty simple to create a few shortcuts if you need to run it at different resolutions, that's what I also do.
