Question Pc not running to its full potential?

May 25, 2020
Hello, recently I was looking at my PC’s benchmarks and saw that the fps I was averaging was far less than others I’ve seen who have the same build. (I constructed the PC via a build guide off youtube that had the same parts). My fps is averaging around 130 fps in game, which is good, but 100 fps lower than what it is supposed to run. Just information about my computer, cable management is subpar, and my CPU use is at 100% but my gpu is only at 10-20 percent. I got that info off the XBOX app so i’m not sure if it’s accurate, i’m downloading MSI Afterburner right now. I figured that the gpu percentage was apart of the issue, but i’m not sure how to fix it. Here are my specs:
RTX 2070
I5 9600K
ASUS Prime Z390 Motherboard
Enermax ETS-T50 Cooling
Corsair Vengance 16 GB ram
EVGA 600 BQ 80+ Bronze Supply
WD Blue 500gb SSD
Seafarers Barracuda 2Tb Hard drive
Around 1500 dollars in total.
Also, my CPU and GPU are not overclocked.
