Question: I heard L.A. Noire for PC now supports DirectX 11.  Who can use this setting and how can I enable it?

Answer: On February 15, 2012, we released a patch to add DirectX 11 support to L.A. Noire.  Here are some facts about the changes:

To get the patch: Launch L.A. Noire while connected to the Internet.  You will be prompted to download the latest patch.

If your patch installation fails and you get an error message: See http://support.rockstargames.com/entries/20632076-error-patching-error-binary-patching-file-what-to-do-if-a-patch-fails-to-install-in-l-a-noire-for-pc

To enable DirectX 11: Run L.A. Noire from the Launcher and enable DirectX 11 in the graphics options.

Supported operating systems: The new DirectX 11 option is intended for players on Windows Vista and Windows 7.  Windows XP does not support DirectX 11.

Graphics card support: In order to enable DirectX 11 in L.A. Noire, you must have a Direct X compatible video card. 

If the game doesn't allow you to enable DirectX 11, or automatically resets to DirectX 9: You may be running Windows XP or your card may not support DirectX 11.

Required drivers: Please ensure that you have updated your video drivers.  For a list of links to find drivers, see: http://support.rockstargames.com/entries/20611671-pc-driver-updates-links-to-third-party-websites-for-the-latest-drivers
