A:Answer You need to be plugged in to use the more powerful graphics discrete card (1060), unplugged you're using the basic intel hd graphics. If you already are plugged in and suffering frames then it must be thermal throttling. Your laptop is hitting the safe max thermal limits slowing down the CPU and/or GPU to ensure it does not go over that threshold. Many gaming laptops are plagued by this issue. It can slightly help if you run fans @max and get a cooling pad. Some have gone to the extreme and changed the thermal paste of the cpu/gpu to liquid metal and even going as far as seriously mods such as cutting out the chassis to make vents for cooling on their laptops. Another way to bypass this is modding you vbios and settings a higher thermal limit. If you consider doing any of these please do your research and at your own discretion. Also to note, despite having a desktop gpu 1060, it is slightly under-clocked the most average actual desktop versions.
