I was playing some game with my laptop that I didn't use for gaming for like 6 months or so (I get back playing games after I quit playing it). I noticed that when I first started the game, it was at nice and steady 60fps, but then in the next 5 seconds it dropped to 20fps, it doesn't even got heated up. Then I checked the usage with Task Manager and realized that it only uses 50%!o(MISSING)f CPU and 100%!o(MISSING)f GPU. Then I started the game again with Intel HD (I was using 940mx before) and yes, it doesn't get better, but I noticed that this time, CPU usage is more than 70%!n(MISSING)ow. I've searched a bit that using integrated GPU doesn't really affect CPU usage.
