Version differences[edit]

Online play is not available in the Mac App Store version (LAN play is supported).[2]

Essential improvements[edit]


v1.4 Patch is the latest patch for the retail version. Retail boxed versions may be SecuROM protected (which requires the disc to be in the DVD drive). This patch removes the protection.

SDK, etc.[edit]

All downloads available for the game can be found at the 3D Realms Prey download page.

Linux client for Prey[edit]

A free client that allows Prey to be played natively on Linux machines. It requires either a full retail copy or the demo to use it.

It can be downloaded here.

SDL Compatibility Library (SDLCL)[edit]

Enables native Alt+Tab and additional screen resolutions by translating SDL 1.2's calls into modern SDL 2.0 on Linux.
Replace libSDL library of the game[3]
  1. Install libsdl2-2.0-0, libsdl2-2.0-0:i386, libsdl1.2debian, libsdl1.2debian:i386, libudev1, libudev1:i386 packages with your distro's software manager.
  2. Backup and remove library in <path-to-game>.
  3. Download sdlcl-1.0-i686.tar.gz; extract into <path-to-game>.

Widescreen resolution[edit]

Some resolutions like 1280x768 and 1920x1080 must be set manually.

Use a custom resolution[citation needed]
  1. Go to configuration file(s) location.
  2. Edit preyconfig.cfg.
  3. Change seta r_customHeight "486" and seta r_customWidth "720" to your desired resolution.
  4. Change seta r_mode to "-1"
  5. Change seta r_aspectRatio to your aspect ratio. "0" is 4:3, "1" is 16:9 and "2" is 16:10.

60 FPS[edit]

Screen tearing on Nvidia G-Sync monitors[citation needed]

Prey may automatically set Nvidia G-Sync monitors to 60Hz with G-Sync disabled. This will result in noticeable screen tearing. This can be fixed by manually resetting the monitor to a higher Hz output. This will not affect the in-game framerate, but will solve the screen tearing.

  1. Go to configuration file(s) location.
  2. Open the preyconfig.cfg file.
  3. Change seta r_displayRefresh to the highest refresh rate your monitor supports.

Issues fixed[edit]

Cannot use Alt+Tab or Command+Tab [edit]

The game does not support directly switching to desktop by Alt+Tab or Command+Tab on Windows and Mac.
Windows: Switch to windowed mode
  1. Switch to windowed mode Alt+ Enter.
  2. Apply Alt+Tab .

Stuttering on AMD Graphics[edit]

Windows: Remove stuttering on AMD Graphics
  1. Rename prey.exe to CoDSP.exe.
Will have to launch the game from the CoDSP.exe or add a non-steam game if using the Steam version.
Linux: Use SDLCL to enable native Alt+Tab
  1. Replace game's libSDL library with SDL Compatibility Library (SDLCL).
Mac: Assign a key for windowed mode
  1. Go to the configuration file(s) location.
  2. Open preyconfig.cfg with a text editor.
  3. Paste bind "F8" "toggle r_fullscreen; vid_restart" at the bottom of the file.
  4. Switch to windowed mode F8.
  5. Apply Command+Tab .

Sound doesn't properly work on Linux[edit]

Install and use OpenAL
  1. Install libopenal1, libopenal1:i386, libasound2, libasound2:i386 packages with your distro's software manager.
  2. Go to the configuration file(s) location.
  3. Edit preyconfig.cfg with a text editor.
  4. Change seta s_useOpenAL to "1"
  5. Change seta s_deviceName to "OpenAL Soft"
  6. Change seta s_libOpenAL to "<path to the>" or symlink to <path-to-game>/

Stuttering in-game[edit]

The game can stutter a few times per second with V-Sync enabled, or showcase significant tearing if V-Sync is disabled.
Change game tick behavior[7]
  1. Ensure the game is configured properly in-game as desired before continuing.
  2. Navigate to <path-to-game>\base
  3. Open preyconfig.cfg in a text editor and add the following lines, then save and close the file:
seta com_PreciseTic "0"
seta com_FixedTic "1"


This also removes the in-game FPS cap (60-62 FPS) but may cause the game physics to go out of sync.[6]
Note that changing any settings in-game resets the file, requiring the lines to be added anew.

    "com_fixedTic [0,1] - If set to 0 (the default) Prey's ticrate is capped at 60, meaning the game framerate cannot exceed 60FPS. If you want to remove this cap, set com_fixedTic to 1, but this causes the game physics to go out of sync. Note, com_fixedTic -1 is no longer supported in recent builds of the Doom 3 engine."
