Batman: Arkham City PC DX11 Patch

Hi all,

We have just released a patch for Batman: Arkham City PC that provides fixes a variety of DX 11 issues, as well as fixes for a few other non-DX 11 related issues. The DX 11 fixes will apply for the majority of players, however, some specific Steam users will experience issues when running under DX 11.
With this latest patch, Steam users with the following Windows Operation Systems should avoid running the game under DX 11 until further notice:

• Windows Vista 32 bit
• Windows 7 32 bit
  Users running Windows 7 32 bit or Windows Vista 32 bit should ONLY use DX 9 settings until a future patch that addresses this specific issue is released. We are actively working to address the remaining issues tied to DX 11 for users running 32 bit versions of Windows Vista or Windows 7.
  Major fixes that this patch addresses are listed below.
• Performance / hitching issues have been greatly improved for running in DX 11.
• An issue with players running out of Video Memory or encountering a Rendering Thread Exceptions has been addressed. This was primarily affecting 32-bit Operating Systems.
• A progression block after defeating Ra�s Al Ghul has been fixed. This was an issue that occurred primarily on lower end computer setups and is described as Batman not readying his Reverse Batarang.
• A crash that occurred when scrolling between the Character Bios and Arkham City Stories has been fixed.
• A crash that occurred when selecting �Press Start� immediately when available at the Title Screen has been fixed. The issue was described as crashing/hard locking around the DLC (Downloadable Content) check.

Thank you all for your patience.
