TweakGuides has created a comprehensive guide for fixing issues in this game. It can be found here.

Widescreen resolution[edit]

Widescreen fixes will break the minimap location reporting, which can be solved using the minimap fix.[4]
Widescreen fixes resolutions of 1366x768 and under will not display dialogue option text correctly and are unplayable.[5]
Video tutorial for widescreen available here
This uses a slightly older version of the game with some bugs (not necessary for the version).[6]
Make necessary changes
  1. Apply the latest Patches (retail versions only).
  2. Download this file (skip this step if you're using the version).
  3. Extract to the installation folder.
  4. Run the game as an admin, then change your resolution to anything else.
  5. Download and run the Universal Widescreen patcher.
  6. Locate your game, set your custom resolution and then patch it.
  7. Go to the installation folder.
  8. Open swkotor2.ini, then delete swkotor.undo1.
  9. Change the following lines in order to set your custom resolution.
[Display Options]
[Graphics Options]


If the custom resolution isn't working bear in mind that the values for the width and height are inverted.

Full Screen Movies[edit]

Guide located here (it is not necessary to edit your .bik files)
Requires the No-CD cracked executable, used in the above Widescreen fix.
  1. Open swkotor2.exe in your favorite hex editor
  2. Calculate your desired movie resolution in hexadecimal, and reverse the bytes. For example, 1920 in hex is 0780 which is 8007 with the bytes reversed. 1080 is 0438, which becomes 3804 with reversed bytes
  3. Replace 80 02 with your desired width, and E0 01 with your desired height, in the following two places (search for these hex sequences):
80 02 00 00 75 15 81 3D E8 C1 80 00 E0 01
80 02 00 00 C7 44 24 10 E0 01 

The resulting hex sequences should look like this, for a 1920x1080 resolution:

80 07 00 00 75 15 81 3D E8 C1 80 00 38 04 
80 07 00 00 C7 44 24 10 38 04

Issues fixed[edit]

Error fixable by going into windowed mode or by changing NVIDIA Control Panel settings.
Error fixable by going into windowed mode or by changing NVIDIA Control Panel settings.

'Stopped working'[edit]

Error occurs after the company logos and before the main menu, or after clicking on 'Load Game' from the main menu.
Full error message: 'Star Wars: Knights of the Old Republic II: The Sith Lords has stopped working'.
Disable Steam Overlay

Going to properties and disabling 'Steam Community In-game' can sometimes fix this issue

Switch to windowed mode

Switching to windowed mode sometimes fixes this issue.[7]

Activate discrete graphics card[8]

Make sure non-Intel graphics card is being used. Intel integrated graphics seems to work for the Steam version but not the retail version in some cases.

Change NVIDIA Control Panel settings[9]

If you have a newer NVIDIA GPU and your game keeps crashing when you click 'Load Game' from the main menu, a detailed solution for this can be found here.[10] The critical detail seems to be changing Threaded Optimization in the NVIDIA Control Panel to OFF

Disable "Frame Buffer Effects"

If the game crashes after initial character creation and you own an AMD/ATI video card, disabling "Frame Buffer Effects" in the game's "Advanced Graphics Options" may fix the issue.

atioglxx.dll from AMD Catalyst 14.4 may allow "Frame Buffer Effects" to work with AMD/ATI cards as described here

Disable "Shadows" setting

If the game crashes unexpectedly from time to time, this is the only way to fix it now. For ex. the crash may be at the Ebon Hawk, on the Prologue level, when you approach the Quadlaser turret.

Stuttering or freezing after combat[edit]

This can be fixed by limiting maximum frame rate.[11]
Apply Vsync
Multi-core fix
If using a multi-core computer, you will need to set CPU single core affinity.
  1. Right click on the shortcut and select 'Properties'. In the target box, type in: cmd /C start "SWKOTOR2" /D "C:\Program Files (x86)\LucasArts\SWKotOR2\" /high /affinity 1 "C:\Program Files (x86)\LucasArts\SWKotOR2\swkotor2.exe"
  2. Replace C:\Program Files (x86)\LucasArts\SWKotOR2\ with where your game install is located. E.g. If you're running 32bit it will be just C:\Program Files\....

Unable to move your character[edit]

Unable to move your character
  1. Hold down both the right and the left mouse button.
  2. Press the quicksave button and keep both mouse buttons pressed during the whole saving process.
  3. Once the saving process is completed your can release both mouse buttons. The character should control normally again.
  • If you encounter recurring issues with being unable to move your character, enabling Vertical Sync will greatly reduce the occurrences of this problem.

  2. Insert the game disc, and ignore any auto play screens.
  3. Open up the Start menu and click on 'Computer'. Right click on the disc drive that has the game disc and select 'Explore'.
  4. Right click on setup.exe and select 'Properties'. Click on 'Compatibility' and select the options 'Run this program in compatibility mode for Windows XP Service Pack 2 (SP2)' and 'Run as Administrator'.
  5. Run setup.exe and install the game as normal. The path where the game is normally installed is C:\Program Files (x86)\LucasArts\SWKotOR2\
  6. Apply the retail patches. Once the patches are downloaded, right click on the files, select 'Properties', and follow the same compatibility settings as was done on setup.exe.
  7. Explore the hard drive and find the folder where you installed the game. Right click on the folder, select 'Properties', un-check 'Read-Only', then click 'Apply'.

Find the installation folder and select the game .exe. To prevent the command window from popping up briefly while launching, under the shortcut properties change the 'Run' mode to 'Minimized'.
  11. TSL Windows Vista Fix needs to be downloaded.
  12. Extract TSL Windows Vista Fix and place the mss32.dll file in the installation folder, overwriting the file of the same name.

Widescreen minimap problem[edit]

Fix minimap location
After applying a widescreen resolution, the HUD elements will be streched and the minimap will not report the correct location.
  1. Download the updated Widescreen UI Fix by Achilles.
  2. Extract content to a folder other than Override folder(i.e. your desktop).
  3. Select EITHER 1920x1080 for 16x9 OR 1680x1050 for 16x10 (but not both).
  4. Copy the contents of the selected folder to Override.

Dialogue options won't display[edit]

Dialogue options will not display on vertical resolutions of 1366x768 or below.
Increase resolution to 1366x785[15]
This causes some of the screen to be cut off at the top.
  1. Using the widescreen resolution method, set the resolution to 1366x795.
  2. Check swkotor.ini has the desired resolution (under the [Display Options] and [Graphics Options] headers):
