Hi, i'm having Dell Latittude E5470 with specs of Intel Core i7-6600U, memory of 16GB and with integrated graphics AMD R7 M360. I'm doing testing such as open a browser, let say with 8 - 10 tabs, with youtube was opened, it seems the video lagging, and the performance of windows also getting slowed, and when i tested some of games, i'm testing MotoGP 13 its quitely smooth, but sometimes a little bit slowing, and then when i try to play some games such as Story of Seasons: Friends of Mineral Town, its using the maximum requirement, and full screen, with VSync disabled, the game is lagging and the frequency of the processor dynamically increasing. Any ideas what's happened? or is there anything that i should do? TIA.
