  6. Start the game again, set in-game resolution to 1920x1080 (or something else).
  7. You can now adjust the display size with the "+" and "-" buttons (or depending on your keyboard, the buttons to the right of 0).
  8. (optional) Install the High Detail Mod.
  9. When starting the game, you might have to click the mouse once to focus it and get sound.

Higher quality graphics

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).

Install the High Detail Mod[5]
  1. Download and extract the High Detail Mod.
  2. Run the installer or copy the files manually.
Doesn't add or replace any textures or models.

Higher quality music

Replaces the music tracks with higher quality ones ripped from the original CD.

Replace .ogg files[6]
  1. Download the High Quality Music.
  2. Run mots_rename.bat in the same folder as the .ogg files to convert them from Jedi Knight tracks to Mysteries of the Sith.
  3. Copy the converted .ogg files to <path-to-game>\Music, overwriting any existing files.
Requires the music wrapper (winmm.dll) to be in the game folder.
Can be combined with the wrapper to allow the retail CD release to play music without the CD.

Higher quality sound effects

Replaces the low quality sound effects re-used from Jedi Knight: Dark Forces II with that game's high quality ones.

Replace JKMsndLO.goo[7]
  1. Download High Quality Sounds (Mysteries of the Sith).
  2. Copy it to <path-to-game>\Resource, overwriting the one there.
Reverts game menus, subtitles and in-game voices to English

Patches

Unofficial patch

Adds compatibility with modern Windows and is required for some mods to work.
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.[8]

Skip intro videos

Delete/rename JKMINTRO.SAN[9]
  1. Go to <path-to-game>\Resource\VIDEO
  2. Delete or rename JKMINTRO.SAN.

Patch FOV to 120°
  1. Download the IPS patches from this page and apply them over JKM.EXE. Note that some in game effects (such as falling bridge in level 9 and lightning pool in level 12) may cause this patched exe to crash, so keep your old JKM.EXE on hand and save often.

Texture/model enhancements

Mysteries of the Sith Enhanced and Retexture Pack

This mod replaces models with higher quality ones taken from Jedi Knight: Jedi Outcast and some completely remade from scratch. It requires the Unofficial Patch and jkgfxmod to be installed.
Install the mod[10]
  1. Download the archive with the modification.
  2. Extract MotSE.GOB and MotSR.GOB to <path-to-game>\Resource.

--or--

  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).
If there are problems with animations during gameplay, then download 'Enhanced and Retexture Pack Animations Fix'.

Jedi Knight Neural Upscale Texture Pack

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.

MotS HUD Revamp

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[11]
  1. Download the archive with the modification.
  2. Extract the motshud.goo and motsgui.goo files into your <path-to-game>\Mod\ folder (create the folder if it does not exist).
  3. Add -path Mod to the command line parameters.
motshud.goo affects the health and ammo readouts and motsgui.goo the force power and item icons.
The larger elements are very different from the original designs.

Issues unresolved

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

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.[16]

Issues fixed

Game won't start

Apply the Unofficial Patch[citation needed]
(Alternative) Use the dgVoodoo wrapper.
(Alternative) Change compatibility settings[17]
  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

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[18]
  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.

--or--

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[18]

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

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[19]
  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

The GOG.com 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

Use -windowgui parameter[20]

Run the game with the -windowgui command line parameter.

Seemingly low framerate or stuttering

The game updates camera movement at only 30 FPS, even though the game runs at 60 FPS. If the game is running at 120fps, the camera updates at 40fps. This can give the appearance of poor performance and can be improved by capping the framerate below 49. Additional side effects (such as first-person weapon animation) may also appear with high framerate. If you only have a 60hz monitor you should probably limit the game to 30 fps (you'll at least get proper weapon speeds) or 47/48 fps if you don't mind some framepacing stutter.

Cap FPS[21]
  1. Use a software that can cap FPS. See Frame rate capping.
  2. Set a cap of 30, 40, 47, 48, 94 or any other variable of 47 (or below) (or below).
  3. The camera should now move at the game's reported frame rate and feel much smoother.

Notes

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

Change the screen size[citation needed]

Press - or = to adjust the screen size.

Menu and/or in-game screen increases in size, get's displaced and cut-off

Disable Windows screen scaling[citation needed]

Go to the Windows screen settings and set the scaling to 100% (default).

Music issues

Music doesn't play or loop or the volume can't be adjusted.

Add/replace music wrapper[22]
  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[23]

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

--or--

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

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

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.[24]
It might not work if you load an old save game, but it works with a new game.
