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.

I bet it's because you're using TXAA. TXAA is broken in this game (the patch may fix it though), and because the AC Unity engine uses deferred rendering, using TXAA or MSAA results in a very large performance hit.
I highly recommend using FXAA instead. It gets rid of 98% of the jaggies and has practically no performance hit.

Quite from the kotaku article link in that twitter link ..
UPDATE 2: 10:34pm Ubisoft has confirmed that the 40GB download is for real. It's not a display error. They posted the following on their official site
Currently there is one known workaround: Owners of the disc version of the game can uninstall the game and reinstall it. On starting the game, the patch process will start with the correct download size.
