I've posted my KOTOR 2 guide at http://magestrix.com/games/KOTOR2_Guide.html and you might find something there that helps.
Cheers, that was very helpful. Unfortunatley, I think Im going to take the game back because even with the fiddling around its still far from smooth and crashes too regularly to be playable, which is a shame as like you the first KOTOR was one of my favourite games. I have a suspicion that it is probably more to do with my computer and my Radeon cards than anything else. Oh well!
