The pre-patched version linked above works with both the original CD and digital releases of the game.
Alternately, the original (non-pre-patched) Unofficial Patch may be used, but it requires the original, installed-from-CD executable.[5]

Remove CD check[edit]

Copy JK_.CD[citation needed]

Can be combined with the wrapper to allow the retail CD release to play music without the CD.

Higher quality graphics[edit]

Before and after the High Detail Mod.
Before and after the High Detail Mod.

Make the game always use the highest quality textures and models, instead of using lower qualities the further away they are (and leading to unsightly transitions).

Issues fixed[edit]

Game crashes at launch[edit]

This issue is present in the original CD release and may also apply to re-releases patched with the Unofficial Patch.
Run the game with the -windowgui command line parameter[11]
(Alternative) Use the dgVoodoo wrapper[citation needed]
(Alternative) Change compatibility settings[12]
  1. Delete Jedi.exe (if it exists) from the installation folder.
  2. Change the compatibility settings for JK.exe to Windows XP (Service Pack 3) and, if using Windows Vista or 7, disable visual themes and desktop composition.

3D acceleration issues[edit]

Running the game with 3D acceleration turned on may cause crashes or graphics problems (ex. black screens) on some modern machines.

(DirectX 10+) Use dgVoodoo wrapper[13]
  1. Download the latest dgVoodoo 2.
  2. Extract dgVoodooCpl.exe, MS\D3DImm.dll and MS\DDraw.dll to your game folder (all three to the root).
  3. Run dgVoodooCpl.exe from your game folder.
  4. Click on the .\ button in the upper right corner of the dgVoodoo Control Panel to set the config folder to the game folder.
  5. Click on the DirectX tab and disable dgVoodoo Watermark near the bottom.
  • (Optional) For the best image quality, also set Filtering to Force anisotropic 16x and Antialiasing (MSAA) to 8x.


Download and extract these pre-configured dgVoodoo wrapper files to the installation folder. They're already configured with the watermark disabled, but are an older version.

(DirectX 9 and earlier) Use alternate ddraw.dll wrapper[13]

Download and extract this ddraw.dll to the installation folder. If that one doesn't work, try this one.

(Alternative) use DDrawCompat[14]
  1. Download the latest DDrawCompat release
  2. Extract and copy ddraw.dll into the installation folder

Can't start new game on AMD GPUs[edit]

This issue is present in the original CD release and may also apply to releases patched with the Unofficial Patch.

Update to the latest AMD drivers[citation needed]
(Alternative) Use the dgVoodoo wrapper[citation needed]
(Alternative) Apply compatibility fix[15]
  1. Download the AMD fix.
  2. Extract JK_AMD_FIX\dll\13.1\atiumdag.dll to the installation folder.
  3. Add parameter -windowgui to your shortcut's Target.

Black screen during menu[edit]

Use -windowgui parameter[11]

Run the game with the -windowgui command line parameter.

Seemingly low framerate or stuttering[edit]

The game updates camera movement at only 30 FPS, even though the game runs at 60 FPS. This gives the appearance of poor performance and can be improved by capping the framerate below 48.

Cap FPS[16]
  1. Use a software that can cap FPS. See Frame rate capping.
  2. Set a cap of 47 (or below).
  3. The camera should now move at the game's reported frame rate and feel much smoother.

HUD is missing or screen has black border[edit]

Change the screen size[citation needed]

Press - or = to adjust the screen size.

Music issues[edit]

Music doesn't play (after exiting the bar) or loop or the volume can't be adjusted.
Add/replace music wrapper[citation needed]
  1. Download this fixed music wrapper.
  2. Extract the .dll files to the installation folder, overwriting any that are already there.
  3. If you don't have a MUSIC subfolder in the installation folder, create one and download the Higher quality music tracks to it. Alternately, if you have an original CD, you can rip the tracks to .ogg files named Track12.ogg to Track32.ogg, yourself.
Works with all releases, even the original CD release.
Disable compatibility settings[17]

Rename JK.exe to JediKnight.exe (or something else)


Download the fixed music wrapper, use a text editor to read and follow the instructions at the top of the single .reg file and then double-click on the file to import it. You can ignore the other files in the archive.

Either should disable compatibility settings installed by GOG/Steam that interfere with music playback (at least in Windows 10).

FOV and Mipmaps/Level of Detail[edit]

Field-of-view is hardcoded to 90° in the game, and level of detail may deteriorate at larger distances while still being noticeable on higher resolution monitors.
Patch FOV to 120 and force highest quality textures/models
  1. Download the IPS patches from this page and apply them over JK.EXE

Miscellaneous fixes[edit]

Nvidia profile settings[citation needed]

If the game crashes with an Nvidia GPU, disable the following settings for JK.exe in the Nvidia control panel:

  • Antialiasing
  • Texture Antialiasing
  • Conformant Texture Clamp

Middleware Notes

Access advanced display settings menu[edit]

Texture/model enhancements[edit]

Jedi Knight Enhanced

This mod replaces models with higher quality ones taken from Jedi Knight: Jedi Outcast. It requires the Unofficial Patch to be installed.

Install the mod[18]
  1. Download JK_Enhanced.zip (or JKE_8bit.zip if playing with software rendering).
  2. Extract JKE\JKE.GOB to <path-to-game>\Resource.


  1. Extract JKE\JKE.GOB to <path-to-game>\Mod (create the Mod folder if it doesn't exist).
  2. Add -path Mod to the command line parameters (unless it's already added).

Jedi Knight Retexture Pack

This mod replaces textures with higher quality versions and can be used alone or with Jedi Knight Enhanced. It requires the Unofficial Patch to be installed.

Install the mod[19]
  1. Download JKR.rar.
  2. Extract JKR.GOB to <path-to-game>\Resource.


  1. Extract JKR.GOB to <path-to-game>\Mod (create the Mod folder if it doesn't exist).
  2. Add -path Mod to the command line parameters (unless it's already added).

JK HUD Revamp[edit]

The original HUD is too small at high resolutions. This mod replaces the default GUI and HUD elements with larger, higher resolution alternatives.

Install the mod[20]
  1. Download jkhud.zip and jkgui.zip from JK HUB.
  2. Extract the .gob file from each .zip into your <path-to-game>\Mod\ folder (create the folder if it does not exist).
  3. Add -path Mod to the command line parameters.
Jkhud.zip affects the health and ammo readouts and jkgui.zip affects the force power and item icons.
The larger elements are very different from and not faithful to the original designs.
