Settings - Resolution - only 16:9 resolutions

[feromagnetic 0]

Hello All,

DayZ seems to have a separate aspect ratio setting which is automatic and offers only resolutions based on a aspect ratio of the display, which is my case 16:9 (3840x2160 native resolution). However for a performance and usually a much better FOV I use a custom 21:9 (almost 21:9) resolution 3840x1646, however I am unable to make it work with DayZ. I also tried to edit the config file directly, setting the WindowHeight to 1646 in DayZ.cfg, however even if I made the file read-only game was running 3840x2160 when I launched the game again (it was the last resolution I have set geme into in-game).

Is there any way to make it work?
