I've managed to finish off my modest Knights of the Old Republic 2 Tweak Guide and it is now available for you to have a look through. Aside from detailed descriptions of all the in-game settings and their performance impacts, it covers all the working advanced .ini tweaks for KOTOR 2, as well as a range of troubleshooting tips which should help you get more out of the game. Hopefully LucasArts will release a patch shortly to fix up the faults in the game which can't be tweaked away.
