[2022] fps cap in 1440p?

I recently started gaming again and upgraded my system to play in 1440p and 144hz. I run a ryzen 9 5900x, 64gb ram, 2 samsung 980 pros for boot and game storage, a 3080ti, and an asus rog swift pg27aqm. but when pplaying division, i get horrible input lag. to the point that if i tapp a movement key, my character will move in the direction endlessly and cannot change direction. it took me forever to realize that no matter what window setting i am in, the game caps at 60hz in 1440p, and if i change it to 1080p, i get 144 fps. and then my input lag goes away. it is only division that does this, is there any reason why its capped at 60fps? or if theres some magic hidden setting i am missing?
