Assassin's Creed Unity Patch 4 is 6.7 GB in size

Patch 4 for Assassin's Creed Unity was released today for Xbox One and PS4, with the PC patch due out later this week. Ubisoft explained the need for a super-sized patch on the official Assassin's Creed website.

As part of our ongoing efforts to provide the best experience for our players, we will be releasing Patch 4 for Assassin’s Creed Unity today. This patch is mainly focused on alleviating performance issues and improving the overall experience. 

Part of the team’s effort to enhance frame rate for players involves replacing and updating portions of the Paris city map where we are seeing issues. This explains the large size of this title update (6.7 GB). However, since a large portion of the patch replaces existing files the net increase to the game’s overall size will be less than 6.7 GB. 

Patch 4 delivers a variety fixes including: 

• Performance & Stability: Frame rate drops, game crashes, lost progression 
• Gameplay: Navigation, lock picking chests 
• Online: Connectivity, matchmaking, companion app 

This Patch is rolling out to Xbox One and PS4 players today and will be available later in the week on PC. You can find the full patch notes here.
