What resolution are you playing at? What is your GPU usage % during the game? Are you not aligning with expected benchmark numbers in other games for the 2060S? Or is this just a case in MW Warzone?

I also have a performance issue with my new 2060 Super XC Gaming purchased last week. 
 
I play MW: Warzone exclusively so I have not tested against other games but I did a lot of research on my expected fps for the card.  I was not impressed when I first installed the card and was getting 80 fps on modified low settings.  I assumed the problem was with my old i7 3770, so I upgraded to Ryzen 5 3600 with a Tomahawk b450, and 2x8 corsair 3,000 mhz.  Kept my original PSU a 650w corsair. 
 
So with my entire new setup on very low settings I am averaging 120-130 fps.  In the demos I have seen on youtube using almost my exact hardware, people are getting 160+ FPS on very low settings.  My card is more on par with a 1660 and I am not pleased after shelling out $450.
 
As for the OP, you need more RAM.  This game is running at about 10gb for me.

I play 1080p, GPU usage hovers around %80

You are handicapping your system with only 8GB of RAM for starters and 100fps sounds right for your hardware. Not sure what you're expecting. 

Are there FPS caps, etc.?  Are the screens the same?  One might have a higher FPS cap and or refresh rate than the other.
