Bethesda have rolled out the 1.0.1.x patch for Fallout 76 that weighs in at 48GB on PlayStation 4 and Xbox One. PC users got off light with only 15 GB, all of which is apparently required to implement performance and stability improvements.
According to the notes, the patch fixes many of Fallout 76 performance issues and hitches, while applying some client and game server improvements. The Xbox One version has had some problems with stability in menus, which Bethesda claim to have eradicated.
Among the more notable changes are PvP ones, where the Pacifist mode players who go PvP while contesting workshops deal full damage. Respawning after dying in PvP will clear active hostile status towards players. Cap rewards when seeking and being sought for revenge will now correctly display the cap amount.
Bethesda tweaked Fallout 76's enemies, where ghoul and scorched officers will drop nuke code pieces when killed and enemies will no longer chase players for longer than intended. Blueprints had a tendency to break into smaller parts when logging out and back in, which has been addressed along with correctly applied paints from the B.E.T.A. and the immediately breaking repaired items.
The Bureau of Tourism bug has been fixed, with Bethesda writing that "the Prickett’s Fort Token Dispenser can now be repaired, and players can no longer walk through it. There have been some minor language, hotkeys and social tweaks as well.
As far as graphics go, Bethesda tweaked ambient occlusion so as to prevent picked up items from retaining shadow outlines and smoothed out the game camera upon entering furniture. "The cover of Tesla Science magazine Issue 9 no longer appears solid red on pickup, or when inspected", which completes Fallout 76's patch notes.
That being said, we're not really sure that this amount of changes warrants 15GB, let alone the 48GB that console users have to download. Bethesda did say however that the future updates will be much smaller in size, so there's that.
