  1. Download and extract the High Detail Mod.
  2. Run the installer and install either Bespin: Cloud City (Bonus Level) or Bespin: Cloud City (Special Edition) (for the fan version with Darth Vader added).

Texture/model enhancements[edit]

  2. Extract MotSE.GOB and MotSR.GOB to <path-to-game>\Resource.


  1. Extract MotSE.GOB and MotSR.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 Neural Upscale Texture Pack[edit]

Vanilla textures upscaled with trained ESGRAN technique. For best results, install after installing Mysteries of the Sith Enhanced and Mysteries of the Sith Retexture Pack.
Requires jkgfxmod.
Textures are raw with noticeable AI artefacting and are intended as a baseline for future texture mods.

Issues unresolved[edit]

Enemies (including the final boss) not activating lightsabers in the last levels[edit]

On the last two levels (Level 13 Sith Temple and 14 Sith Temple Catacombs) some enemies appear as stone statues with lightsabers. Sometimes some of them (but not all) fail to activate their lightsabers and therefore just run after the player. This can happen with the final boss as well, who is still able to hurt the player by different means.

All versions including the original release may be affected. A potential fix is to simply restart the game a few times.[17]

Issues fixed[edit]

Game won't start[edit]

Apply the Unofficial Patch[citation needed]
(Alternative) Use the dgVoodoo wrapper.
(Alternative) Change compatibility settings[18]
  1. Delete Sith.exe (if it exists) from your game folder.
  2. Change the compatibility settings for JKM.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[19]
  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. Make sure the game works before trying these.


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

(DirectX 9 and earlier) Use alternate ddraw.dll wrapper[19]

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

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.
(Alternative) Use the dgVoodoo wrapper.
Apply compatibility fix[20]
  1. Download the AMD fix.
  2. Extract JK_AMD_FIX\dll\13.1\atiumdag.dll to your game folder.
  3. Add parameter -windowgui to your shortcut's Target.

Game runs in a window even when set to fullscreen[edit]

The and Steam launchers and shortcuts may add the -windowGUI command line argument to preemptively solve a black screen problem experienced on some systems.[1]

Run the game directly with <path-to-game>\JKM.EXE.

Black screen during menu[edit]

Use -windowgui parameter[21]

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 can give the appearance of poor performance and can be improved by capping the framerate below 48.

Cap FPS[22]
  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.


This will cause frame pacing issues on non-variable refresh rate monitors, resulting in the game as a whole actually feeling less smooth.

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 or loop or the volume can't be adjusted.

Add/replace music wrapper[23]
  1. Download this fixed music wrapper.
  2. Extract the .dll files to your game folder, overwriting any that are already there.
  3. If you don't have a MUSIC subfolder in your game folder, create one, download the Higher quality music tracks to it and run the included .bat file. Alternately, if you have an original CD, you can rip the tracks to .ogg files named Track02.ogg to Track14.ogg, yourself.
Works with all releases, even the original CD release.
Disable compatibility settings[24]

Rename JKM.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).

Miscellaneous fixes[edit]

Nvidia profile settings[citation needed]

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

  • Antialiasing
  • Texture Antialiasing
  • Conformant Texture Clamp

Extreme waggle/swing in first person view[edit]

The swing or waggle velocity and movement of the weapons in first person view can be a little extreme and fast, being worse if you are using mods like jkgfxmod, making this a little bit distracting in the game action.

Extract the mod Half Waggle Weapon Speed Mod in the game folder.[25]
It might not work if you load an old save game, but it works with a new game.
