Why is my nitro underperforming?

RCXDINBOUND

So I noticed that my Nitro is underperforming in gaming in alot of aspects, 

For example these following games should run well but for me they run on very weirdly fluctuating FPS

Fortnite for example, on another acer nitro performs about 136 to 110 on low. While on the same settings, my laptop goes to 75 to 53 all the time.

Rainbow SIX Siege is supposed to be above 80 most of the times on low, but for me its 70 to 50

GTA V performs the worse for me, instead of atleast being 60 or 70 fps, it goes down to 50 and 30

My laptops specs are
Intel core i7 7700HQ 2.8 Ghz [3.6Ghz most of the time because of turbo boost]
RAM: 8
GTX 1050ti 
128 GB SSD
1 TB HDD
