Version differences[edit]

While the Steam version is cheaper, the version has no DRM and offers bonus free content.

Essential improvements[edit]


The 1.112fm patch fixes various bugs and adds multiplayer. Digital distribution versions already include this patch as do some retail re-releases.

Deus Exe[edit]

Kentie's Deus Exe is an updated executable that integrates support for various features. It does not work with the GameStop (Impulse) version of Deus Ex.

This fix will replace the existing deusex.exe file within the folder. If you want to be able to uninstall it, backup the main executable beforehand.

Using Deus Exe
  1. Install Deus Ex normally. For CD versions you must choose the full install option.
  2. Download the latest version of Deus Exe (If using Windows XP download 5.3 version instead)
  3. Install Microsoft Visual C++ 2013 Redistributable Package (x86).
  4. Extract the Deus Exe files to <path-to-game>\System folder, replacing the existing deusex.exe when prompted.
  5. Set your options in the pre-game launcher.

Direct3D 10 renderer[edit]

Kentie's Direct3D 10 renderer improves compatibility with modern systems and adds native support for various features including anti-aliasing, anisotropic filtering and multi-monitor resolutions.

  • If you are using Deus Exe, install the renderer then choose Direct3D 10 Support in the launcher.
  • If you are using the original Deus Ex, install the renderer then run Deus Ex in Safe Mode and choose Direct3D 10 Support from the list.

Run without the CD or Steam[edit]

Retail: remove CdPath= line from deusex.ini


A number of mods have been released for Deus Ex which include improvements to texture quality and gameplay adjustments:

Deus Ex: New Vision[edit]

Deus Ex: New Vision replaces the vast majority of the game's texture files with HD remakes, drastically improving the visual appeal of the game. It is compatible with Kentie's Custom Launcher, however note that to use these improved textures an additional renderer is required. 2 are included in the New Vision download, one for DirectX and one for OpenGL, and a video demonstrating full installation of the mod with Kentie's Launcher can be found here.

Deus Ex HDTP[edit]

Deus Ex HDTP (High Definition Texture Project) is a mod aimed to remodel and retexture the majority of the game's assets. The mod is currently in beta stages. The newest version can be downloaded either through Mod DB or from the Off Topic Productions forum thread, which also list all the progress on the updates.


GMDX (Give Me Deus Ex), winner of Moddb's 2014 Mod of the Year "Worldly Award" is a mod for the Deus Ex campaign. GMDX improves Deus Ex's AI considerably, polishes and expands upon weapon behavior, fixes bugs, expands upon and refines the RPG systems (Augmentations, skills and weapon mods) as well as a vast number of other game systems, adds a new difficulty mode, improves audio & level design, just about everything has been polished and expanded upon in GMDX except for the plot.


Shifter fixes many common annoyances with the game, including improved enemy AI and a restructured augmentation system which replaces augmentations considered obsolete by the developer of the mod. Note however that this mod makes the game significantly easier by increasing the number of skill points awarded and items dropped among other things.

  • BioMod is an alternative extension to Shifter, further adding game changing features such as autosave and automated augmentations. Also notable is the removal of Shifter's awarding of skill points for kills.

The Nameless Mod[edit]

The Nameless Mod is an extensive conversion of Deus Ex which provides a new storyline within the Unreal 1 engine set outside of the Deus Ex universe. This modification is fully voiced and includes many new weapons and features.

Deus Ex: Nihilum[edit]

Deus Ex: Nihilum (also known as DXN, DEN and Nihilum) is a "mod taking place in an alternate Deus Ex continuity". It takes some content from other mods and provides around 10 hours of gameplay. It includes around 3.5 hours of voice work and 2 hours of new audio.

Deus Ex: Revision[edit]

Upgraded version of the game. See Deus Ex: Revision for details.

Issues fixed[edit]

32-bit color won't enable[edit]

Use Deus Exe, and set 32-bit color in-game and restart the game before changing any other settings

Audio stutter/game crashing due to audio subsystem[edit]

If problems persist, adjust the audio latency setting in the launcher.

Crash when enabling 32-bit color[edit]

Patch the game up to 1.112fm
Switch to an alternative renderer

Error message crash on startup[edit]


Generally speaking the error message will detail the subsystem in which the crash occurred in so you can narrow down the possible causes. You can also access the game's logfile (Deus Ex\system\deusex.log) for additional information.

Game Speed Inconsistent/Jerkiness[edit]

Large-scale graphical glitches[edit]


This is usually caused by the chosen renderer. Launch Deus Ex in Safe Mode and change to a different renderer. If problems persist, try the Direct3D 10 renderer.

Shadows appear scratchy/green[edit]

GUI scaling issues[edit]

Use Deus Exe and set the GUI scaling option appropriately

Depending on the resolution (e.g. 1366x768), the GUI may still be too small or too big, use AHK Injector instead.[citation needed]


After the release of the 1.112fm patch Ion Storm released an official SDK for the game which includes a full level editor and conversation editor. Note however that it is possible to crash the SDK by excessively spawning some items including rockets.
