It's not for KOTR, but the concept is sound.
A lot of Star Wars Battlefront 2 users which dual-core CPUs such as the AMD X2 or Pentium D series, as well as users with Pentium 4 HyperThreading CPUs (i.e. "virtual" dual cores) are having problems with this game. The reason appears to be because the game suddenly places 100% load on both cores and locks the system, or crashes to desktop with no error message. This can occur at any time during the game. The solution involves using one of two methods:
Setting Processor Affiinity Manually: Launch Star Wars Battlefront 2, and as soon as the game appears to begin loading, or after it has loaded up, press CTRL+ALT+DEL to bring up the Task Manager. Under the Processes tab, find the BattlefrontII.exe process, right-click on it, select 'Set Affinity' and in the box which appears, untick 'CPU 1'.
Setting Processor Affinity Automatically: If you want to force the game to only use one of your CPUs automatically each and every time you run the game, see the instructions here for using the Imagecfg utility, a small Windows NT file you can safely copy into your WindowsSystem32 directory and then use to permanently set the affinity for particular programs. I recommend you backup your BattlefrontII.exe file before applying this tweak, as the only way to undo it is to restore the original .exe file. Furthermore, note that you may have to redo this tweak each time you patch the game, since the executable will change.

And one more edit: Here's a link from BioWare's support forums. Looks like it's a combination between dual core and Nvidia. http://swforums.bioware.com/viewtopi...65728&forum=80Edited by e_dogg - 6/5/08 at 8:36pm
