My idea about FOV is specified in the link posted to me last post.
And I agree with the WSGFWiki:
Vert-:
A vert - game is a game that when played on a widescreen monitor with a widescreen resolution, decreases the vertical component of the FOV.
Hor+:
A hor + game is a game that when played on a widescreen monitor with a widescreen resolution, expands the horizontal component of the FOV while keeping the vertical component roughly or exactly the same.
Unreal engines behavior is ALWAYS vert- native, although you can set the FOV manually to reach the hor+ like U wrote. If the commong meaning here of the hor+ is this (a hor+ native or a vert- than can be fixed) it's ok for me.
In every game I tested with U engines, I can modify the fov in more than a way (menu and/or .ini and/or console command), so U-Engines are hor+ here.
So it's better to fix here:
