little question about FOV instructions

[Amyr]

In the section of 3.B.1. Optimize FOV, it says that adding fov tweaks into ini files does not persist and therefore it should be done via console ingame.

I didn't quiet get what does not "persist".

 

I have these lines in my Skyrim.INI under Display section;

 

fDefault1stPersonFOV=81.0000

fDefaultWorldFOV=81.0000

fDefaultFOV=81.0000

 

I've been playing every save with these INI tweaks for the last year and I didn't have to make any changes since than. Am I missing something here? These values were 65 in the default.ini(the one that you get by typing saveini on a fresh game) and then I just changed it to 81 and it works. I never had to type fov 81 ingame with these tweaks. I usually play in first person.

 

P.S. Excuse me for my poor English.
