My friend recently bought a laptop with an AMD A8-3500m APU (an HP Pavilion dv6-6140us
, to be exact). I tried updating its integrated Radeon HD 6620G to the latest Catalyst driver set (11.8) but it didn't work. The mobile driver version didn't even acknowledge that the PC had AMD graphics hardware, and the desktop driver set updated a few things but didn't update the graphics drivers themselves. Is there anything specific I need to do to upgrade the graphics drivers on a mobile Fusion APU?
