Eidos Montreal, Square Enix, and Nixxes are happy to provide an additional patch for Deus Ex: Human Revolution that addresses various issues players have reported since release. We hope this patch will allow them to further enjoy playing the game.

The patch includes:

- Some players accounted a problem where the Tai Young Medical shuttle in Hengsha would not arrive. This has been resolved.
• Existing save-games can be loaded and continued from normally, the shuttle will now arrive.
- We have provided a workaround for stability and performance issues on AMD FX CPUs with specific firmware versions.
- We have made further changes to reduce stuttering in the game.
• Improvements to background streaming of resources. (on DX11 only)
• Workarounds have been added for issues that can happen with Windows asynchronous file IO.
• We have improved parallelism with the graphics driver on dual-core machines. (should also benefit machines with more cores)
- SSAO has been improved to look less noisy.
- Various minor issues with 3DVision have been resolved.

- A fix for some players that get stuck on an infinity loading screen in Detroit.
- Fixes for some issues that caused crashes for players using specific firewall or proxy software.
- Additional improvements to counter stuttering in the game.
- Support for Eyefinity in combination with 3D when using interleaved stereoscopic monitors.
- Support for additional brands of stereoscopic interleaved monitors when using AMD graphics hardware.
- Support for Nvidia 3DVision.
- Support for Nvidia Surround, also in combination with 3DVision.
- Improved control over the stereo-3D display in the game.
o The allowed range for the stereo 3D Strength setting has been increased.
o A Stereo 3D Plane setting was added to provide additional control over the 3D effect.
- Various performance improvements.
- Fix for ‘moire’ issues seen on billboards in DX11 mode.
- Some changes to try to counter specific driver issues causing crashes in DX11 mode.

Unfortunately the recently released patch had a negative impact for some players. This patch is a hot-fix to address those issues.

- A specific issue that caused performance degradation for some DX9 players in the 1.2.630 patch has been fixed.
o We are still evaluating further measures to counter stuttering and plan to have a further update for this in another patch.
- Crashes when examining quest items have been fixed.
- Some issues related to switching between fullscreen and windowed mode have been fixed.
- Additional fixes have been made for the TYM medical card. The current fix should also allow users that already have the problem in their savegame to pick up the card again.
- ‘Russian’ text language option now shows up correctly regardless of current text language.
- An issue that may cause the game to have stability issues on certain RAID setups may have been addressed. Even with this patch, if you have a RAID setup, please ensure you have the latest drivers for your controller.

In addition to stuttering and performance problems we are continuing to investigate any other issues that players may have and will release a full new patch soon that also includes the previously mentioned 3DVision and Surround support.

The new patch addresses a variety of issues as well as adds some new features:

Fixes:
- We have addressed various issues that can occur for players that would result in ‘stuttering’.
o Stutters that are the result of graphics driver shader processing are now removed or significantly reduced.
o Stutters that are the result of data streaming have been removed or significantly reduced.
o Performance has been improved and made more stable on dual-core systems. This could previously also result in stuttering.
- Fixed issue where some players couldn’t complete the Motherly Ties side quest.
- Fixed an issue where doors in Omega Ranch sometimes wouldn’t open.
- The TYM medical card should no longer fall through the table if an NPC’s body comes into contact with the card. Players already stuck in this area will need to revert to a previous save before the card fell through.
- Occasional hangs for some players during video-playback have been fixed.
- A crash on startup when running DX11 on a single-core CPU has been fixed.
- An issue causing Eyefinity setups to not be correctly detected for some players has been fixed.
- Fixed an issue where the HUD would get permanently disabled for some players.
- Fixed certain issues that caused the mouse cursor to be able to leave the game-screen on multi-monitor setups.
- Fixed an issue that caused the mouse cursor to not be visible in-game when the user has mouse trails enabled in Windows. We still recommend disabling mouse trails for a smoother in-game mouse cursor.
- Fixed issue where ammo count for collected guns is incorrect when Adams weapon is augmented.
- In DX9 mode:
o Fixed error message for some users when trying to use FXAA Medium or FXAA Low anti aliasing modes.
o Fixed shadow-mapping ‘lines’ on some graphics hardware when using anisotropic filtering.

Feature Additions:
- The Enter and Numpad-Enter keys can now be bound to game actions in the keyboard control menu.
- Intro logos can now be skipped on all but the first run of the game.
- Added windowed mode.
o Selectable in the menu, and can be toggled between windowed, fullscreen, and fullscreen windowed using ALT-ENTER.
- Added an option to change the text language of the game. This setting only changes the text language, the audio is controlled by the language option in Steam.

On top of this we are continuing to monitor for any issues that may need to be addressed in a future patch. One extra feature we can already confirm for a future patch is support for Nvidia 3DVision and Nvidia Surround.

We hope this patch will allow players to further enjoy Deus Ex: Human Revolution.

This latest patch addresses:

• A frequent issue for AMD/ATI hardware users that can cause the game to crash on startup.
  
• Improvements to loading speed. The speed increase depends on machine spec and settings, but loading time improvements of over 50% have been measured on some machines.
  
• Some control fixes:
  
  • Diagonal movement is no longer faster as intended.
    
  • Adjustments have been made to mouse sensitivity in response to user feedback.
    
    • Mouse sensitivity for X and Y axis can still be configured separately, but is now consistent when set to default settings.
      
    • The range of settings for mouse sensitivity has been adjusted to provide for more accurate adjusting.
      
    • The default mouse sensitivity has been altered to be somewhat less sensitive.
      

An issue was found that caused some users to be unable to start the game on specific machines. Specifically, the presence of older ATI/AMD drivers, also on machines with NVidia hardware, would cause the game to crash on startup. This patch is a hot-fix for that particular issue. On top of this, it also increases the number of save-slots from 20, like on the PS3 and Xbox 360 versions, to 99.

Square-Enix, Eidos Montreal and Nixxes are committed to supporting this title and will continue to monitor for any further issues and provide additional patches in the future if required.

We hope this will help you enjoy Deus Ex: Human Revolution!
