Batman: Arkham City has just been released for the PC and although Rocksteady had a full month to tweak their game, it appears that the current build features a bugged DX11 mode. In other words, the DX11 path is causing performance issues and that’s something that Warner Bros has officially acknowledged. In order to avoid these issues, players are required to run the game in DX9 mode for the time being.
According to the company’s US Manager, Andy Cataldo, Warner Bros received a lot of reports about Batman: Arkham City’s PC low performance. After researching, the company has found that running the game with DX 11 is causing the performance issues. Warner Bros and Rocksteady are working on a title update to address this matter and expect to make it available in the near future.
So for the time being, PC gamers are required to run the game in DX9 mode. Here are some instructions for changing DX11 to DX9:
