Suddenly getting alot worse performance

[LiquidDonut]

I've been struggeling with some horrible fps drops and just horrible performance overall. Yesterday i was having 80-120 fps on bf4, but today i kept dropping to way below 60, even on low settings. And even on leauge my frames were dropping below 60 at times. Usually it stays at atleast 150. What is going on?

Specs:
MSI GTX 770
i5 4670k @ Stock Speed
MSI z87-g43

EDIT: My temps are normal, staying at about 70c (GPU) under full load.
