Several demo versions of Deus Ex are available at Planet Deus Ex, including the first two missions as well as a Macintosh version.

Version differences[edit]

While the Steam version is cheaper, the version has no DRM and offers free bonus content.
The version fixes a bug that accidentally removes the music during your last visit to Hell's Kitchen.

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.
This patch unintentionally removes music from the Hell's Kitchen map on your last visit. The problem is present in all versions GOTY, except the one sold on

Deus Ex Maps Patch[edit]

D.X.M's Deus Ex Maps Patch replaces the outdated maps from the 1.112fm patch and fixes various bugs.
This patch does not replace the multiplayer maps for compatibility reasons.

Deus Exe[edit]

Kentie's Deus Exe is an updated executable that integrates support for various features.
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.
Does not work with the GameStop (Impulse) version of Deus Ex.
FPS limiter in new versions of DeusExe causes freezes when opening menus. See Game freezes when opening menus.[1]
Using Deus Exe[citation needed]
  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++ 2015 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.
Usage[citation needed]
  • 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.

Improved graphics[edit]

Game can be vastly improved graphically by the New Vision and HDTP mods. See Mods.

Cap the framerate to 120fps[1]

Deus Ex: New Vision[edit]

Replaces the vast majority of the game's texture files with HD remakes, drastically improving the visual appeal of the game.
Compatible with Kentie's Custom Launcher.
An additional renderer is required. Two 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 (High Definition Texture Project)[edit]

Remodels and retextures the majority of the game's assets.
Currently in beta stages.
The newest version can be downloaded either through Mod DB or from the Off Topic Productions forum thread.

GMDX (Give Me Deus Ex)[edit]

Extensive gameplay mod that improves every aspect of the game excluding the plot and soundtrack.
Including both New Vision and HDTP. One download, all-encompassing.


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.
This mod makes the game significantly easier by increasing the number of skill points awarded and items dropped.


An alternative extension to Shifter, further adding game-changing features such as autosave and automated augmentations. Also, the Shifter's awarding of skill points for kills is removed.
