i recently bought a DELL Inspiron 15R 2012m Series Laptop. It comes with a built-in AMD Radeon 7670m graphics card.
I installed PES 2012, when I checked the system specification (an option in that PES 2012 game ). I came to know that game runs with Intel HD4000 Graphics and not with my AMD card.
I also changed the swithchable graphics and assigned High Performance to PES2012, but the game still runs on Intel HD4000.
