Oh I should have mentioned, I stopped using the FPS unlocker I linked in some old post and moved over to
Flawless Widescreen. I don't actually use the widescreen part of it, but the ER plugin has a bunch of other nice shit like FPS unlock, removing chromatic aberration and FOV increase. You do need to disable EAC for it to work though, all you do is go into the game directory, copy eldenring.exe, then replace start_protected_game.exe with the copy of eldenring.exe.
After that you can just start from Steam as usual, naturally this disables online mode so it's no good if that's important to you.
