I have a Samsung 7 series notebook, Model number: NP700Z5B-S01UB. It contains an AMD HD6490M GDDR5 512MB graphics card. However, the notebook seems to only use the Mobile Intel HD Graphics card inherent in the motherboard. I know this because it is what comes up when I run dxdiag which states it's using a 258MB card.
I have already updated the drivers several times. I have updated my BIOS. I have made contact with Samsung Support. They only told me to update my drivers. I even tried turning dxdiag.exe to be set for High Performance in the Catalyst Control Center's section for "Switchable Graphics".
Please help me, AMD Forums! You're my only hope!
