Widescreen resolution[edit]

Disadvantage Widescreen fixes will break the minimap location reporting, which can be solved using the minimap fix.[4]
Disadvantage Widescreen fixes resolutions of 1366x768 and under will not display dialogue option text correctly and are unplayable.[5]
Information Video tutorial for widescreen available here
Information This uses a slightly older version of the game with some bugs (not necessary for the version).[6]

Fix 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]


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

Full Screen Movies[edit]

Information Guide located here (it is not necessary to edit your .bik files)
Information Requires the No-CD cracked executable, used in the above Widescreen fix.

Fix Instructions

  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.

'Stopped working'[edit]

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

Fix Disable Steam Overlay

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

Fix Switch to windowed mode

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

Fix 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.

Fix 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

Fix 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

Fix 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]

Information This can be fixed by limiting maximum frame rate.[11]

Fix Apply Vsync

Fix Multi-core fix

Information 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]

Fix 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.
