I have a 9700pro and have had several issues w/ various drivers. First I was using the unian drivers based on the cat 5.1's. The game would not even launch w/ these at 1280x1024. Then I reverted back to the 4.12 drivers everything seemed fine for a while, then I froze up loading a cut scene. I tried the 5.2's and froze up on a cut scene, plus i crashed to the desktop once. I also tried the open gl driver from cat 4.2 and 4.11. With 4.2 the performance was not too good at all and I did get kicked back to desktop once. With the 4.11 thigns were going good until the first swoop race. Now if I beat any of the track records when the game goes to load back to the cantina it crashes me back to desktop. Im going to try to edit the ini file now.
