Ive done that, been working my down with the windows Computer Management, however i used the AMD auto detect, which told me the best driver was "catalyst_mobility_64-bit_util.exe" however after it downloaded and the setup ran, i was told "AMD Catalyst Mobility cannot be downloaded due to incompatible hardware/software on your computer. The version of your graphics adapter is not supported"

In terms of Catalyst Mobility, how major is this driver, and should i try to get it?

P.S i know you should try to have the most recent drivers, but this sounds like a "Extra Feature" Driver more than anything
