Warner Bros. removed Batman: Arkham Knight from Steam in June because that version of the game was essentially too broken to function. Today, it re-launched Arkham Knight on Steam, though some players are still experiencing problems. In an effort to address these issues, Warner Bros. posted an update with a few suggestions for specific problems: Windows 7 players may encounter hard-drive paging issues after "extended gameplay sessions," but "re-launching the game will resolve" that. For Windows 10 players, Warner Bros. says, "having at least 12GB of system RAM on a PC allows the game to operate without paging and provides a smoother gameplay experience." It should be noted that 12GB of RAM would provide a smoother gameplay experience for just about every game in existence. The studio is also looking into stabilizing the experiences on specific graphics cards.
