hi,I havea very strange problem,my radeon 9600pro freezes when playin' ut99 for about 30minutes..It doesn't happen in any other game..I have catalyst 5.11b,is there any option that shoulb be disabled?
other thin,my card has a little broken piece..it is the size of an ant..I think it's not that is causing the problem....

Try updating your drivers. Or look for a patch..

I sold that card about a year ago..9800pro now
