Upgrade from rtx 3080 to rtx 3090 dropped FPS.

[Natrina]

Hi guys. I just upgraded 

From zotac rtx 3080 amp holo black 

To 

Upgraded to MSI rtx 3090 suprim X 

I was expecting to have a FPS boost

Of at least 10 percent. COD WARZONE.

BUT  instead of FPS going up. 

It went down !  

180 to 200 fps ( rtx 3080)

( After MSI afterburner)

160 to 190 FPS ( rtx 3090)

( After MSI afterburner ) 

Settings are set excatly the same in game. 

I did ddu to reinstall drivers after changing the card . I also changed PCI type to gen 4

I updated my window / MB bios too.

Nothing works ! My fps is still lower 

Than when I was using rtx 3080 zotac !

I tried doing benchmark and my score 

With rtx 3090 is higher than rtx 3080!

By around 2000 score. The problem only happens when I go play in games. 

I also noticed that my gpu usage is around 60 to 75 percent when I'm in cod warzone. 

( Using MSI rtx 3090 suprim )70~80degree

My current full build is 

Mb - x570 Aorus master 

Cpu - ryzen 9 5900x

Gpu - MSI suprim X rtx 3090

Ram - gskill trident z neo 3600mhz 16x2 (32gb ) total.

Ssd - Samsung Evo plus 970 1tb

Hhd - 1 tb Toshiba 

Psu - seasonic focus gx 850w

Fully Gold modular .
