Major fps issue on my gaming laptop for ow2

I have been playing ow2 for a little time now, and I got back on after a month or so, and my fps wont go above like 30-40, before this I would get 200 fps, and it’s not my computer, I run mw3 and val and fortnite and dbd at high frame rates (100-300 fps) and its just overwatch, I have no idea how to fix this, I tried reinstalling the game and tweaking the settings, I really need help on this, me and my friends are all trying to paly but I just can’t.
