If DICE can put in a FOV slider for Battlefield 1, why can't Bethesda do it for Skyrim?
Bethesda won't do these kind of requests and will almost certainly ignore them. Lots of people wanted a head bob toggle in Fallout 4 because of motion sickness but Bethesda did not acknowldge this or do anything about it.
I'm sure mods will address this, its really easy to have 1 console command to change the fov and make it load somewhere
Not for PS4, the console command would have to be issued by a custom script, which is a banned asset.
