I think I've found something helpful.

After hours of tinkering, I finally found the graphics settings file ( User/AppData/Local/Divinity 2/Profile/graphicoptions.xml ), and lo and behold, the resolution was stored wrong. Setting to 1920 x 1080 in the game resulted in 1680 x 1050 in the file. I simply changed the res manually in the file, and boom, AA works! At least, in 1920 x 1080.
