I have a number of problems with my Sapphire Radeon HD 4870 Vapor-X 1GB and latest catalyst 10.2 drivers. The main and the biggest problem is with the game Prince of Persia. I've shown and described it here: http://www.youtube.com/watch?v=ljFURRlP2mM.
Another issue is that with 10.2 drivers the refresh rates of my monitor aren't correctly recognized by the card. With 1440x900 resolution i can't set 75Hz refresh rate. The only options are 60Hz and 59Hz (?! 1Hz lower? strange). With older drivers there is no problem to set 1440x900 75Hz.
And last - since catalyst 9.5 i can't run most of the older 2D games (such as Planescape Torment, Baldurs Gate, Worms World Party) properly. I experience fps freezes or poor fps overall.
Currently I'm using an old 9.3 driver and it seems that it is working fine. But why do I have such problems with newer versions?
