I'm running a 32:9.
 
	Ultrawide does work, you just need to manually tweak FOV from the GameUserSettins.ini file to ~145, otherwise the image is too "zoomed". (CustomFieldOfView=145.000000)
 
	Bad Workaround I know. Somehow it seems to be a thing that in-engine cutscenes render at 16:9 regardless of the game.
