Need help with Ultrawide

I have been trying to enable ultrawide for the game I am working on, but I am now stumped.

Most threads on this that I can find suggests that I should enable “Maintain Y-Axis Fov” in the Editor preferences, but doing so does not seem to change anything? As far as I understand, changing this should have a noticable difference on the FOV of the game unless you adjust it to compensate, but I cant tell any actual difference.

I am using the node “Set field of view” to set my FOV, does it automatically compensate for what you set “Aspect ratio axis constraint” to? Or do I need to do something else for the changes to the editor preferences to go through?
