Laptop GTX965M 100% GPU usage Low FPS

[RlPsoul]

Sometime when I start a game, my FPS significantly dropped from what it was normally (150+) down to 10-50 fps depends on the game (Fortnite, League of Legends, Roblox).
This started happening after Fortnite partnered with NVIDIA and enable Highlights in game. I accidentally pressed yes to turn it on when it asked and my FPS instantly dropped since that day. It so happened that by enabling Highlights, it turns on my Game bar, which made the lag happens to all games. But I did not know this and completely wiped the laptop to make it like a new one ( called factory reset I think). Then I turned off Game Bar and the fps went back to normal but a new problem rose: 100% GPU usage sometimes ( mostly it's fine), and FPS is very low (mostly it's 150+). Sometime in League of Legends, a simple Alt+Tab fixed it (just sometime, not always). This is bothering me for over a month now and I saw a lot of posts saying that 100% GPU usage is normal. It's not normal for me, when I use 100% GPU, my fps drop significantly.
