Help me, Interwebs Kenobi... you're my only hope.

Good News: Knights of the Old Republic makes me happy. It's rebuilding my Star Wars squee to pre-prequel levels. It makes me so happy that I'm even managing to stay mostly Light Side.

Bad News: It's crashing like a bastard. Keeps freezing once I go into menu screens or cut scenes, and the graphics keep going weird and flickery on me. Yes, I have Googled this fault, and found nothing helpful. Are there patches in obscure locations I should be downloading? Should I perhaps be forcing this process to run on a single core? Do I need to fiddle with my graphics card settings?

Please. You want me to stay good, don't you?
