Low FPS in Warzone

Hi friends and foes

I just upgraded my gaming rig from Geforce MSI 1080 8GB to ASUS ROG 1080ti 11GB.

BUT I still only get 90 fps in games like Warzone and Battlefield like I did with my 1080 MSI.
Not a big upgrade but sure, I must get more fps with a larger GPU?

I am running:
AMD Ryzen 5 2600X
1080ti16 GB
HyperX Fury 1333MHz.
1080p 144Hz

I have tried to uninstall drivers and the game but still no luck.

Any ideas are welcome?
