Arkham Knight came out last night at midnight, with some crippling effects on the PC port.

Arkham Knight was originally developed for the consoles, and ported over by a third party company for Rocksteady games. The game, which features a proper conclusion to Arkham Asylum and Arkham City, was a highly anticipated release after the failed Arkham Origins, released by Warner Bros. Games, Montreal.

Arkham Knight has had a smooth launch for the consoles, but being locked on to 30fps for the PC has caused a bit of an uprising, and stuttering video and audio has just gotten people upset.

Rocksteady studios took to the Warner Brothers forums (who have published all 4 Arkham games) to make sure the community knew they were heard.

We’re aware that some users are reporting performance issues with the PC version of Batman: Arkham Knight. This is something that Rocksteady takes very seriously. We are working closely with our external PC development partner to make sure these issues get resolved as quickly as possible.
