3090 zotac slow

I've recently built my 1st pc, Rog strix f - 3700x - zotac 3090 - 32gb 3466mhz ram. Everytime I load up warzone or cold war i cant get more than 120 fps, I play with people on 2060supers and they are getting the same fps but I've tried everything and nothing is changing it, really not sure what...
