I've been playing around with FOV in FO4 after giving the FO76 beta a few tries, and noticed BethINI only touches the setting for third-person. Ran a good chunk of tests, and ended up with this: "fDefault1stPersonFOV" Ongoing game: Controls first-person FOV. New game: Controls first-person FOV and viewmodel FOV/size for weapons and Pip-Boy. "fDefaultFOV" Ongoing game: Affects size of the translucent backgrounds that are part of the main menu and HUD, loading screen background, Power Armor HUD and Power Armor Pip-Boy. New game: Same as above. (Don't touch this one, obviously.) "fDefaultWorldFOV" Ongoing game: Controls third-person FOV. New game: Same as above. Only the FOV for weapon and Pip-Boy viewmodels are baked into the save, which is derived from fDefault1stPersonFOV on a new game start, but it can be permanently changed for your playthrough with the FOV console command. For example, "FOV 80 100" for someone with a FOV of 100. So if you want your FOV higher than default (and without super tiny weapons and Pip-Boy) for a new playthrough, you need at least some form of involvement; A. Start with all changes in place and apply the FOV tweak once with the console command. or B. Start without changes to fDefault1stPersonFOV, save and quit as soon you can, apply changes to fDefault1stPersonFOV and you're ready to continue playing. On a sidenote, the FOV settings behave almost identical in FO76. The only difference I could find was that seemingly none of it was part of the save (see "new game"), but your viewmodel FOV would reset to default either over time or with the use of VATS/Power Armor. (Didn't pinpoint the culprit exactly.)
