I have a asus k53tk laptop and it has an amd hd 7670m dedicated graphics card. Amd catalyst says I can enable dual graphics which i think is also called amd crossfire x. Now I've enabled show amd radeon dual graphics status icon (where applicable). When I play games like league of legends and need fore speed the icon doesnt show up. Does it mean dual graphics isnt working? I've also set these games to high performance in amd dual graphics settings so that dual graphics works on these games. My question is is dual graphics working?
