How to change FOV permanently?

[Soapess]

My game lauched by F4SE from MO2. When I type "FOV 90 90" in the console, FOV changes immediately, but when I save&load the game, the first person FOV reverts back to 75, and the 3rd person FOV stays at 90. And I serached for resolutions to change the 1stPersonFOV permanently. Like all the instructions says, I added

"fDefaultWorldFOV=90
fDefaultFOV=90
fDefault1stPersonFOV=90"

in my fallout4.ini and fallout4prefs.ini in MO2's exclusive INI folder (you know the exclusive archive in profiles folder). It changes nothing. 

What's dramatic, when I typed "refreshini" in the console, the FOV turned to 90 according to my ini. However, when I save&load, it reverted back to 75. And the command "saveini" was invalid too.

How can I solve this?

One of your mods might be reverting your FOV with an INI file or a script.

Try using the "autoexec" function.

In Fallout4.ini under [General], add the line:

sStartingCommandConsoleCommand=bat startup

 

Now, in your FO4 folder (where the Fallout4.exe file is), create a file called startup.txt

 

In that file add the line:

fov 90 90

I simply installed FOV Slider and Player Height :

Requirements are F4SE, Mod Configuration Menu and (optional but recommended) ConsoleUtil.

Allows you to separately configure (via MCM) field of view for 1st and 3rd person views, power armour, terminals (how “zoomed in / out” you are when viewing in-game terminals) and your hands / weapon (I think this is called “view model”).

It’s very comprehensive and works perfectly (on 1.10.163 at least, not sure about next gen).
