Widescreen resolution[edit]

Not necessary for Steam version.
Widescreen fixes will break the minimap location reporting, which can be solved using the UI fixes.[6]
Widescreen fixes resolutions of 1366x768 and under will not display dialogue option text correctly and are unplayable.[7]
Video tutorial for widescreen available here
This uses a slightly older version of the game with some bugs (not necessary for the version).[8]
Make necessary changes[citation needed]
  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.

Ultra-widescreen resolution[edit]

Ultra-Widescreen fixes will break the minimap location reporting, which can be solved using the UI fixes (instructions included below).
Using Flawless Widescreen can cause memory leaks, which in turn can corrupt your current save file.
Apply the following instructions
  1. Download and run the Flawless Widescreen application.
  2. In Flawless Widescreen, search and install the "STAR WARS : KOTOR II" plugin.
  3. Download the updated Widescreen UI Fix by Achilles.
  4. Extract the contents to a folder other than Override folder (i.e. your desktop).
  5. Select 1920x1080 for 21:9 and copy the contents of the selected folder into Override.


Unfortunately there are no 2560x1080 (21:9) version files, but the 1920x1080 (16:9) version works and displays just fine.
The Flawless Widescreen application must be up and running every time before launching the game.


Windowed[citation needed]
  1. Go to the configuration file(s) location.
  2. Edit swkotor2.ini.
  3. Add AllowWindowedMode=1 under [Graphics Options].
  4. Change FullScreen=1 to FullScreen=0.

Full Screen Movies[edit]

This method does not work on latest game version.
Guide located here Archived (it is not necessary to edit your .bik files)
Requires the No-CD cracked executable, used in the above Widescreen fix.
Instructions[citation needed]
  1. Open swkotor2.exe with a hex editor such as HxD.
  2. Determine your desired movie resolution expressed in hexadecimal notation, and reverse the order of the bytes. Each byte is two hexadecimal characters, so you want to make sure that you're not entering the hexidecimal string backwards but are instead separating it into bytes (2 character chunks) and then reversing the byte order (the reversal has to do with the order data is stored in and read from memory, which is called endianness). For example, 1920 in decimal notation is 0780 in hexadecimal notation, which is 8007 with the bytes reversed. 1080 in dec is 0438 in hex, 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]

"Stopped working"[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.
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'.
Switch to windowed mode[10]

Switching to windowed mode sometimes fixes this issue..

Activate discrete graphics card[11]

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[12]

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.[13] The critical detail seems to be changing Threaded Optimization in the Nvidia Control Panel to OFF

Disable "Frame Buffer Effects"[citation needed]

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[citation needed]

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.[14]
Apply Vsync[citation needed]
Multi-core fix[citation needed]
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]

This is a known issue with running the game at a refresh rate higher than 72 Hz.
Unable to move your character[citation needed]
  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.
  • You can also lock your framerate on 60 by using nvidia control panel or riva tuner.
Enable vsync in the graphics options or in the launcher and set refresh rate on 60hz[citation needed]

Low performance[edit]

Disable frame buffer effects[15]
Low Frame Rate[16]
The Steam version has by default the wrong syntax in the swkotor2.ini for enabling this OpenGL method for storing vertex data in video memory.
  1. Go to the installation folder.
  2. Locate file swkotor2.ini
  3. Edit and change DisableVertexBufferObjects=1 under "[Graphics Options]" to Disable Vertex Buffer Objects=1

Retail installation for Windows 7[edit]

All steps should be done with an administrator account.
Working on Windows 7 x64 bit.
Retail installation instructions[17]
  1. Install the DirectX End-User Runtimes.
  2. Insert the game disc, and ignore any auto play screens.
  3. Open 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'.
  8. Right click on every .exe file in the installation folders and set the compatibility modes to the same as in step 4.
  9. Right click on the kotor2.exe and select 'Create shortcut'. Move the shortcuts to your desktop.
  10. This shortcut needs to be set to 'Run as Administrator'. To change the icon to the shortcut, click on 'Properties' and then 'Change icon'. A new box will open. 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.

Stretched UI on widescreen resolutions[edit]

After applying a widescreen resolution, the HUD elements will be stretched

Subscribe to Widescreen UI (stretch fix)


16:9 only
  1. Download the updated Widescreen UI Fix by Achilles or Improved Widescreen Experience.
  2. Extract content to a folder other than Override folder(i.e. your desktop).
  3. Select EITHER 1920x1080 for 16:9 OR 1680x1050 for 16:10 (but not both).
  4. Copy the contents of the selected folder to Override.

Dialogue options will not display on vertical resolutions of 1366x768 or below[edit]

Increase resolution to 1366x785[19]
This causes some of the screen to be cut off at the top.
  1. Using the widescreen resolution method, set the resolution to 1366x785.
  2. Check swkotor.ini has the desired resolution (under the [Display Options] and [Graphics Options] headers):
[Display Options]

[Graphics Options]

The game crashes on Intel HD Graphics (Linux, Wine)[edit]

The issue is that game uses very old OpenGL which is not compatible with modern drivers. These steps also fix various graphical bugs.[citation needed]
  1. Install Iris Mesa Driver. It's also available from Oibaf ppa or you can download extracted driver from here.
  2. Run MESA_LOADER_DRIVER_OVERRIDE=iris glxinfo to check if driver works correctly.
  3. Make a script in the game directory with following parameters:


wine swkotor2.exe
MESA_EXTENSION_MAX_YEAR variable is required to fix graphical issues during playing. Disabling shadows can resolve some graphical issues too.
