Last month Blizzard announced that an update for Overwatch was coming to PC that would increase the tick rate, and now Lead Engineer Tim Ford and Senior Engineer Philip Orwig have explained how this will work in a new video.
They say that the netcode update has rolled out to most servers and will come to more later on, adding that the game should now have a higher tick rate and added tech to scale down update rate for slow connections.
Regarding consoles, however, they say they are still investigating how the same things can be applied there.
