Just bought an Radeon 5700 XT after a friend suggested that AMD had been better on drivers than Nvidia had, after installing this card I found that I cannot run Kotor 1 with frame buffer effects, a feature that makes up half of the graphic effects in the game. Dropping the catalyst bits in the file does not function so don't even ask, will not take turn it off for an answer and it will be reported.
P.S. The Vertex effects work on this card on Kotor 2,
