SWKOTOR2 Crashes crashed a lot when I tried to play it.  My problem lay with the drivers installed for the NVIDIA Geforce 8500 GT graphics card.  They can be downloaded here.  Another problem involves jumpy graphics or suddenly moving really fast or whatnot.  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.

Setting Affinity  After much toying around and researching I came up with a few solutions.

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.

Other options include ImageCFG which many sites rave about, but honestly I was not able to get this simple utility to work. If I were able to get this to work then any program that I apply it to would have its affinity permanently set to one processor or another. I am somewhat wary of "permanent"

I looked at links that discussed altering the registry, but decided against it as it was a little more involved than I wanted.

The most useful thread ––> here discusses a wide range of solutions for the handling of older games on multicore systems.

It was here that I found a simple little program called win2000 Launcher 1.5.2 that allows me to set the priority of any program. It's simple and also allows me to set the priority and is not permanent and it works.

Glitches  If you play light side you must choose to not give up your weapons to the handmaidens.  When in the Secret Tomb on Korriban do not side with Kreia.
