Extremely low usage on GPU (5-10%) but higher on CPU usage. (50-70%)

Hi, recently got this game.

I play the game on a 1440p 75hz monitor.
Been playing it for 3 days or so now and realised that when i’m in game my gpu usage is anywhere from 4-10% and my average cpu usage is 60%…
Sometimes a few cores are at 100% for a short period of time.
Reason why i’m concerned is that, am i able to get more fps if it uses my gpu more? I get 50-60 fps on high with shadows turned off.

My specs are:

CPU: I7-7700
GPU: Asus rog strix gtx 1050ti oc
RAM: 16 gbs corsair vengence
Game is installed on a WD 1TB HDD

I understand that i have a budget gpu but i’ve played other games and they mostly take up almost 100% utilization.

Are there any fixes?

Thank you
