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.

GTX 970 SLI shouldn't have issues with this game. I have G1 GTX 970 SLI and I can easily sustain 60 FPS in AC Unity at 1440p maxed settings, so you should be getting similar.
Are you on Windows 7 or Windows 8.1?

I just hope this will make the game playable... I went back to AC:Unity yesterday after taking a break from DA:I, and was baffled that it still has issues. Poor SLI scaling, poor GPU usage, and the stuttering... it's still there! I have no ideea why it is happening, there seems to be no ram/vram leak, it's simply weird and makes the game unplayable when you're in the middle of an action sequence.
