The Elder Scrolls Online's PS4 patch is 15.9GB

The Elder Scrolls Online's PS4 patch is a colossal 15.9GB.

The reason for this is that it contains all the content from the PC version's first three patches, developer ZeniMax Online Studios noted on Twitter.

As such, it makes numerous changes to the game's performance, UI, questing and bug-fixing.

The full patch notes are as follows:

Alliance War

General

• Fixed an issue where your game could crash when teleporting to a forward camp or keep in Cyrodiil.
• Fixed an issue where you were unable to view campaign information or POIs on the Cyrodiil map after joining a new campaign.

Art & Animation

General

• Fixed an issue that was causing grass to flicker.
• Fixed an issue that would cause Lyris to not walk properly on stairs during the tutorial quest.
• Fixed an issue where particle effects would block your view in some cases while in first-person view.

Combat & Gameplay

General

• Decreased the frequency at which you'll run into invisible NPCs and ensures they will appear if you do run into the problem: This is an ongoing work in progress, and you may still run into an invisible NPC occasionally. If this occurs, please wait and the NPC should appear within 30 seconds.
• Grouped Veteran Rank player characters of any level will now receive both experience and loot credit, regardless of their contribution.

Itemisation

• Fixed an issue where Glyphs of Weapon Damage were granting more effectiveness than intended when paired with the Infused trait.

Item Sets
