Warner Bros. has released a Steam patch for Batman: Arkham City that fixes a variety of DirectX 11 issues, plus a few problems not related to DirectX 11.
The patch does, however, come with one rather large problem for 32 bit gamers - Steam users running 32 bit Vista or Windows 7 should stay clear of running the game under DirectX 11 until further notice.
"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 issue tied to DX 11 for users running 32 bit versions of Windows Vista or Windows 7," explained Warner.
Major fixes that this patch addresses
- 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 address. This was primarily affecting 32-bit Operating Systems.
- A progression block after defeating [spoiler] has been fixed. This was issue occurred primarily on lower end computer setups and 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.
