Problem: Basically my computer usage / CPU Usage is extremely high for most games and i dont get the FPS i should be getting. 100-120FPS on League of Legends and same on CSGO.

Im playing Overwatch, suddenly i see my FPS drop down to 120-90. I check Task manager, CPU is up at 99%/100% and the only thing i have up running is chrome. I know chrome takes up CPU space, but with my CPU and computer, it should be able to handle it.

And when im playing CSGO, League of Legends, Overwatch, Fortnite or any other game my CPU usage is around 90-100%.

My computer is about 4/5 months old now. My computer is a beast and it should be performing without any problems what so ever, especially on a game like fortnite and its running 100% GPU Usage?

CSGO i might understand cause its CPU demandin but League of Legends, giving me 100-110FPS and CPU running at 100%, with the computer and setup that i have? I dont understand.

The Usage on games is extremely high, and ive downloaded MSI - X Boost, ANd command Center, and the rest of the programs and updated every thing. I have downloaded malwarebytes and CCleaner to check if i have a miner or something hogging up the CPU but it couldnt find anything. I dont know what the problem is or how to solve it. Any and all help is appreciated.

Fortnite: Sometimes both CPU and GPU is at 100%.
