Random FPS drops

Hi there! I’ve come back to Overwatch after one year break and experienced weird random FPS drops. I have recorded example but i can’t paste link to this post :confused:. I have no idea how to describe it more specific with only words. I have latest drivers for GPU and latest W10 update. My friend also experienced this issue. This issue occurs on lowest and ultra settings.

My setup:
Intel i7 7700
GTX 1060 6GB
16 GB DDR4 RAM
