“Deus Ex: Mankind Divided” is less than a week from release, so its developers at Eidos Montreal have started to discuss day-one patches. We also have details regarding its size and the changes in store.

Prior to the update’s formal detailing, game director Jean-François Dugas spoke to App Trigger about the unfortunate necessity of day-one patches. “You can test, and test and test, but there are always new ways and possibilities to test something that nobody tested it before,” he said. “We have the fix for the players but we cannot include it on the disc, and so sometimes it becomes this day-one patch that is not necessarily needed for the player to enjoy the game, but it is recommended to have the best possible experience.”

Above all, it’s not something he likes, but he calls it “part of our reality.”

As for “Deus Ex: Mankind Divided” specifically, its day-one update notes have been revealed thanks to retailers that decided to sell console versions of the game before its release date. On PS4, the initial patch weighs a hefty 3.6 GB and is intended to remedy “various crash fixes, functionality and improvements to CPU and GPU optimization.” Everything is already live on the PlayStation Network for those that manage to snag a copy early.

Day-one patches have been a hot topic in the games industry as of late with the recent launch of “No Man’s Sky” on PS4 and PC. That game’s gold build was exceptionally unique in terms of excluding major features from the experience that aren’t present on the retail disc. Those without an Internet connection to download the patch could therefore have a fundamentally lesser experience without the fixes installed. If the changelog for “Deus Ex: Mankind Divided” is any indication, that won’t be happening here. All post-release alterations appear to add polish as opposed to content.

“Deus Ex: Mankind Divided” follows 2011’s “Deus Ex: Human Revolution,” so it plays by the franchise’s established stealth-RPG roots. As Adam Jensen, players must find a way to stop groups of augmented humans that have recently become a deadly force.

The game is available worldwide on Aug. 23 for PS4, Xbox One and PC.
