Star Wars Knights of the Old Republic II – troubleshooting
written by: admin

Date Written: 8/5/11 Last Updated: 2/13/22


This game crashed a lot when I tried to play it.  My problem lay with the drivers installed for the NVIDIA Geforce 8500 GT graphics card.  The ones I had installed were from Windows Update.  When I installed the drivers directly I did not have this problem.  The drivers I installed were 275.33.  The drivers can be downloaded here.

Jumpy graphics or suddenly moving really fast

This is actually a problem with many older games trying to run on computers with multiple processors.  To fix this hit Ctrl+Alt+Del and right click the application and set the affinity to one processor.  It does not matter which.  To make this automatic read this thread from dynamicdrive.com.

Permanently Setting Affinity

  • Option 1 Priority Master 2009 is a program that will allow you to set the affinity among many other things. I downloaded it and discovered that it is free and then $13 to buy after 15 days even though it is listed as one of the free (not free to try) downloads from cnet. I set the affinity and then uninstalled the program. The affinity was maintained even after the Priority Master 2009 program was uninstalled. The "bad" news is that I can't alter the default affinity anymore for that program, which is fine I guess since it now operates better.

  • Option 2 ImageCFG  
    • Download and unzip this file.  
    • Place it in the system32 folder.  
    • right click the shortcut to your game or program, select properties and copy the contents of the line from either the "start in" or "Target" location.  
    • Open the run command prompt and paste it there including the quotes and place the following command right before the quoted location "imagecfg –a 0x1 " without the quotes.  It should look something like
      imagecfg -a 0x2 "C:\Program Files\LucasArts\SWKotOR2"

    • Hit OK.
    You will see a DOS prompt pop up for about 1/20th a second and then disappear.  Your program will have an affinity permanently set to processor 1 as opposed to all of your CPUs.  With this program you can also revert the affinity back to using multiple processors.

  • Option 3 win2000 Launcher 1.5.2 It allows you to set the priority, but is not permanent. ref

  • Option 4 In the Target for your shortcut use:
    C:\Windows\System32\cmd.exe /C start "" /affinity xx "C:\Your_Program.exe"

    01 – 1st CPU
    02 – 2nd CPU
    03 – 1st and 2nd CPU
    04 – 3rd CPU
    05 – 1st and 3rd CPU
    06 – 2nd and 3rd CPU
    07 – 1st 2nd and 3rd CPU
    08 – 4th CPU
    09 – 1nd and 4th CPU
    0A – 2rd and 4th CPU
    0B – 1st 2nd and 4th CPU
    0C – 3rd and 4th CPU
    0D – 1st 3rd and 4th CPU
    0E – 2nd 3rd and 4th CPU
    0F – 1st 2nd 3rd and 4th CPU

Playing Lightside

  • If you play light side you must not choose to give up your weapons to the handmaidens.
  • When in the Secret Tomb on Korriban do not side with Kreia.
If you do either of these you will still be able to play the game, but you will be unable to progress further.  The game will have effectively hit a dead end.

The Sith Lords Restored Content

With Steam after downloading the patch browse to the folder where KOTOR2 was installed.  For me in Windows 7 it is located C:\Program Files (x86)\Steam\SteamApps\common\Knights of the Old Republic II and must be installed inside that folder.

To tell if this has been installed you will see a logo for the mod on the start screen.

Widescreen Support

KOTOR 1 and KOTOR 2 were not designed to run on much higher resolutions like 1920x1080.  To achieve this you will need Universal Widescreen for KOTOR 2 or Flawless Widescreen for KOTOR 1

The instructions are given in the patches and are easy to read and follow.  Two points bear repeating from their instructions:

  • Flawless Widescreen needs to be running before starting to play KOTOR 1.
  • The game must be run and then exited a few times before the changes take effect.  For me it took about 12+ times to run the game and exit and then start it up again.  I also restarted my computer once or twice.  After that the game ran perfect without any hitches at 3840x1600.  see gog forums for more info.

  • Be sure to edit the swkotor2.ini file then under [Graphics Options] and [Display Options] and change the width and height to what you want.
  • Then in the game use 1280x960 resolution to view the new resolution.  The game only needs to be patched once.
  • This patch needs to be applied after installing the TSLRC 1.8.3 patch.
