hey, i have a hp pavilion 15 (p010ax) with A10-5745m and dual graphics 8610G + r7 260m. i am using windows 8.1 (64-bit). whenever i try to play any game it will only use Hd 8610G only and won't switch to r7 260m. i have tried switchable graphics menu but i didn't work. i have attached a screenshot. i have installed AMD catalyst v8.0.916.0. Can someone help me with this?
