Deus Ex: Human Revolution

What works

Played the entire game (with keyboard and mouse) on Sway, a Wayland tiling WM.

What does not

Had quite a few issues, however, the "bad" ones are easily fixable:

• By default, the game uses DirectX 11, and I've experienced graphical errors with it. All the character models disappear and all you see is their eyes. Tried enabling/disabling CSMT, that didn't help. However, this is easily fixed by switching to DirectX 9 in the game settings.
  
• (after switching to DirectX 9, I tested out Gallium Nine - saw no graphical errors, but no real performance improvements either. I played most of the game with standard WineD3D)
• In certain situations, the mouse input becomes completely messed up: the slightest mouse movement causes the camera to point in random directions on every frame, as if the sensitivity was set to 10000x of normal. The "Capture mouse movement in fullscreen" setting from winecfg does not help. The only fix that I could find is to run the game in Windowed mode, or use a virtual desktop.
• The mouse movement problem also appears when switching between different "contexts", for example when quitting out of the pause/augmentations menu, or when getting in and out of cover. If you move your mouse even slightly while exiting the pause menu, your camera will point to a random direction. I have not found a fix for this. Just don't move your mouse while exiting menus.
  
• The game hangs on exit, takes two minutes for the window to close.
• I've had a couple of crashes during gameplay. The game auto-saves quite often, so this was not a massive issue, but still quite annoying.

Workarounds

Enable DirectX 9, and enable virtual desktop. Don't move your mouse while exiting menus.

What was not tested

Haven't completed all the side quests. Haven't tested controller input.

Follow these guidelines to avoid embarrassment when your Test Submission is immediately rejected!!

• Put your PC specifications in the Extra Comments section e.g. like your CPU and system memory.¹
• When adding test results please specify video card and driver version you are using.²
• It's also useful to mention what Desktop Environment you are using (e.g. KDE/Plasma, Gnome, Xfce, Budgie, Mate, Cinnamon, ...)
• Specify if you installed the Deus Ex: Human Revolution into a fresh Wineprefix (or not).
• Specify what version of the Windows compatibility you use for your Wineprefix (e.g. Windows XP, Windows 7). Specify if you override this for the Deus Ex: Human Revolution executable.
• Specify whether you installed into a 32-bit or a 64-bit Wineprefix.
• Add detailed comments about what is not working for you.
• Please indicate if your using Wine Staging and/or any additional patches applied - to the version of Wine you are using.
• Please, don't submit test results like "Everything is working" or "Everything isn't working".

These guidelines ensure your submitted test results are actually relevant to other users of Wine and WineHQ.

1 The console version of the lshw utility is your friend. This command will dump your System hardware specification in a clean format. Post command and output in the Extra Comments section:

sudo lshw -short | egrep -v '(volume|disk|bus)'

² glxinfo can be used to display your OpenGL and graphics driver versions. Post the command and output in the Extra Comments section:

DirectX 11 Support

As of Wine version 1.7.53(+) there are tests enabled to see if your graphics hardware supports DirectX 11... Unfortunately a significant amount of the DirectX 11 translation layer has still to be implemented in Wine.

On supported hardware, Deus Ex: Human Revolution – Director's Cut will start in DirectX 11 mode. The menus will display correctly (some dialogue boxes may appear to be undersized??) In game there will be a lot of graphical corruption and missing textures.

The workaround is to disable support for the DirectX Graphics Infrastructure (DXGI) in Wine:

wine reg.exe ADD "HKEY_CURRENT_USER\Software\Wine\AppDefaults\DXHRDC.exe\DllOverrides" "/v" "dxgi" "/t" "REG_SZ" "/d" ""

Graphical Corruption

Wine, by default, does DirectX draw calls in a different order from Deus Ex: Human Revolution – Director's Cut running under Windows.

The workaround is to enable strict draw ordering (via a registry key):

wine reg.exe ADD "HKEY_CURRENT_USER\Software\Wine\AppDefaults\DXHRDC.exe\Direct3D" "/v" "StrictDrawOrdering" "/t" "REG_SZ" "/d" "enabled"

In addition the AlwaysOffscreen registry setting is enabled by default (since wine version: 1.5.10). It is important that this registry setting should be left enabled.

Mouse Escapes Window (Wine Virtual Desktop mode)

The symptom of this problem is that when Deus Ex: Human Revolution – Director's Cut is run in a Wine Virtual Desktop the mouse can escape from the fullscreen game window.

The workaround is to enable the grab mouse in full screen mode setting (via a registry key):

wine reg.exe ADD "HKEY_CURRENT_USER\Software\Wine\X11 Driver" "/v" "GrabFullscreen" "/t" "REG_SZ" "/d" "Y" /f

This is a workaround introduced by Wine Bug 6971 - Mouse "escapes" window or is confined to an area in the full screen program.

Incorrect DPI Scaling of Elements

The symptom of this issue is that all UI popup elements, the in-game HUD, etc. are scaled to an inappropriately small size. This appears to manifest on a single-head X session with multiple monitors, combined into a single X display.

The only known workaround is to use a Wine Virtual Desktop. The issue is to be investigated further as no Wine bugs appear to be filed against it.

In-game stuttering and generally low FPS

Enabling StrictDrawOrdering leads to a high price in game performance. It is recommended, certainly for Nvidia GPU users (using the proprietary driver), to use the Wine Staging CMST patchset available in the Wine Staging package. AMD GPU users who are using Gallium Nine may not require or benefit from this patchset.

This unstable feature can be enabled in the Staging tab of the winecfg utility. Regressions (crashes, graphical artifacts, etc.) should be reported at the WineHQ Bugzilla - stating that the Wine Staging patchset was used.
