The thing about multiplayer games is that bandwidth is always an issue. While there are some games that are a bit more forgiving, there are some where the slightest delay in response could mean the difference in victory and defeat. Given the fast pace nature of Overwatch, the game definitely falls into the latter category.The good news is that this is something Blizzard has been taking note of, and it looks like they have finally rolled out high bandwidth servers for the game. According to Blizzard, they are “currently in the process of rolling out high bandwidth support globally for PC. This process may take a few weeks for all regions, but once fully deployed all games including those in Quick Play and Competitive Play will be running in high bandwidth mode by default.”
What does this mean? Ultimately this means that your game should feel more responsive. “In Overwatch, our high bandwidth option adjusts the game’s client update rate (the frequency at which your client gets updates from the game server) from 21 updates per second to 63 updates per second. This reduces the amount of time between when you complete an action and when your client hears back about the result, which in turn will help make the game feel more responsive.”
Blizzard also notes that because not all internet connections are equal that they are also including the ability to adaptively scale down your update rate if they think that your connection is unable to keep up. As the developer notes, the rollout should take a few weeks so if you don’t see it yet, don’t worry as it should eventually find its way to you.
