MW and Warzone PC

Ive been having trouble playing MW and warzone. When I play its as though I am lagging . The game pauses, skips, jumps, etc… Its unplayable atm. Im playing with the same settings Ive always played with and never had any problems until recently. Cold war plays just fine. Anyone else ran into this kind of problem? Wondering if I need to do a reinstall.

CoD is not a Blizzard game and even if it was this is the API forum.
