I had the EXACT same problem on my other computer. Knight of the Old Republic works FINE on this computer, but downstairs it craps out. And this computer's got a worse graphics card. Eventually I went into the setting for Kotor, which are at default set up for people with Cray supercomputers, and turned everything down a few notches. It worked fine after that.
...until you get to the part where you're fleeing the planet in the ship and trying to blast the Sith fighters...
But anyway... |
