Since early September Overwatch has become unplayable for me. I tried contact blizzard but their support page for some reasons won't let me submit ticket.
Initially I saw huge performance issues with the game out of nowhere, fps dips and slight latency increases. Although, I have started to believe their in game latency doesn't show the full image but only what is going on on last hop. Nothing wrong with my pc on other games (tested hardware as well) and didn't experience same issues on games with different routing such as Paladins for example.
