Can't you just download the package and choose advanced install and uncheck catalyst control center and keep display drivers+wdm?
After playing on these for a while it seems that my frames are a LOT higher than with 6.10. I mean it really does feel smooth, but I have graphical anomolies. (spelling error there? oh well). In guild wars when things used to slowly appear in the distance and come into quality gradually, now start out looking like they are in the distance, flicker, turn into a black square, then when you get closer, the object appears. When you stand still everything looks normal, it's just black boxes in the distance appearing on mountains and stuff while you run. I'm going back to the drivers on my CD, cause I'm sick of these issues. Go modified 6.8's for my x1950xtx. SIGH.
