I actually reinstalled older drivers which fixed this issue the first time. I reinstalled a few older ones now but it didn't change anything. AMD Adrenalin updated them without me knowing which caused the issue the first time, but this time it I don't think drivers caused the issue, unless creation kit or F4SE somehow altered them or the way FO4 uses them. I tried lots of other things like modifying .ini files, verifying game files, compatibility settings and even reinstalled windows the first time. None of those worked, only older drivers did.
