So recently my laptop wont run aaa games like before such as fortnite i would get about 90 frames but now im getting 12. So i checked what was going on and the problem was that my laptop was automatically switching from gpu to igpu back and forth. i have tried everything i cannot get the same results as i used. I have even tried to go on invidia control panel and set the 3d Settings to high performance gtx 960m. But the problem still is on going. Plz help!!
