Deus Ex

What works

Installation via GOG Galaxy 2.0, single-player mode, OpenGL, DIrectX and Software renderers.

What does not

Can't launch the game through Galaxy client or through the provided desktop shortcuts (see bug 48308). You must to go to the game's System directory and launch DeusEx,exe manually.

When using a tiling WM (Sway), the game sometimes crashes when entering fullscreen. Enabling virtual desktop via winecfg fixes this.

Sometimes the game just refuses to start for no apparent reason (either crashes on startup or hangs). But after a few attempts, it launches properly and is very stable.

OpenGL renderer results in very "wonky" graphics: when you get too close to certain objects, their geometry starts deforming. The software renderer produces a lot of z-fighting for some reason. I recommend that you stick to the default DirectX renderer, even if the FPS is slightly lower as a result.

Workarounds

Virtual desktop is recommended.

What was not tested

Multiplayer.

Hardware tested

Graphics:

• GPU: AMD
• Driver: open source

Additional Comments

Out-of-the box the stock OpenGL renderer will generate a segmentation fault:

This BASH script will fix the DeusEx.ini file settings to correct this. Note it is recommended to use the newer OpenGL renderer (which is significantly better)

1. Create this script (credit to Morgawr, his original script was used as a basis for this):
#!/bin/bash




#export WINEPREFIX="❚❚❚❚❚❚"


export DEUS_EX_PATH

# Read install path for Deus Ex, from the Wine Registry.
# Note: this requires a first run, when DeusEx is installed under Steam.

DEUS_EX_PATH="$(
     wine reg query 'HKEY_LOCAL_MACHINE\Software\Unreal Technology\Installed Apps\Deus Ex' /v Folder 2>/dev/null \
        | awk '{ if (sub("^[[:blank:]]*Folder[[:blank:]]*REG_SZ[[:blank:]]*","")) print $0 }' \
        | dos2unix
)"

# Fallback to 'C:\DeusEx'

DEUS_EX_PATH="${DEUS_EX_PATH:-C:\\DeusEx}"

printf "Using DeusEx (Windows) install path: '%s'\\n" "${DEUS_EX_PATH}"

# Convert path from Windows to Unix format

DEUS_EX_PATH="$(winepath -u "${DEUS_EX_PATH}" 2>/dev/null)"

if [[ ! -d "${DEUS_EX_PATH}" ]]; then
     printf "DeusEx install path: '%s' ; does not exist\\n" "${DEUS_EX_PATH}" >&2
     exit 1
fi

# Patch settings to make the game work properly on OpenGL devices
# Uses the default DeusEx install path (for the current WINEPREFIX)
if ! sed -i -e '/FrameRateLimit=60/d' \
              -e 's/^GameRenderDevice=.*$/GameRenderDevice=OpenGLDrv.OpenGLRenderDevice/g' \
              -e '/^GameRenderDevice=OpenGLDrv.OpenGLRenderDevice$/a\FrameRateLimit=60' \
              -e 's/FirstRun=.*$/FirstRun=1100/g' \
         "${DEUS_EX_PATH}/System/DeusEx.ini"
then
     printf "Unable to update DeusEx.ini file: '%s'\\n" "${DEUS_EX_PATH}/System/DeusEx.ini" >&2
exit 1
fi

printf "Successfully updated DeusEx.ini file: '%s'\\n" "${DEUS_EX_PATH}/System/DeusEx.ini"

2. Make the script executable & run it:
   chmod +x fix_deus_ex_opengl.sh
   ./fix_deus_ex_opengl.sh
   (ensure your WINEPREFIX env variable is set)

The Kentie Launcher Deus Exe is a replacement executable for Deus Ex. It's compatible with the GOTY edition of the game, which includes the Steam version. Note: the enhanced Steam version of DeusEx appears to lose support for the high resolution/wide screen fixes, when the Kentie Launcher is installed.

The launcher:

• fixes various issues running the game on modern computers
• helps you configure the game
• includes a mod manager

Kentie Launcher homepage

This script will download version 8.1 of the Kentie Launcher and automatically install it, to the specified WINEPREFIX.

Update the KENTIE_VERSION variable as required.
