An anonymous reader writes: Back in June, Warner Brothers removed Batman: Arkham Knight from sale after a lot of graphics and performance issues found on the PC version. Now, after spending five months trying to fix this mess, Rocksteady and Warner Bros re-released the game on Steam with some free Batman titles for those who acquired the launch edition. However, Warner Bros noted there are still a few caveats with Windows 10 users recommended to have 12GB of RAM to avoid paging issues: "For Windows 10 users, we've found that having at least 12GB of system RAM on a PC allows the game to operate without paging and provides a smoother gameplay experience." Some initial tests show no performance gains on the re-released version. Warner Bros claims that it's still working closely with its GPU partners in order to enable SLI/Crossfire for the game.
