Blizzard brings out high bandwidth servers for Overwatch with increased tick rates of 63Hz rather than 21Hz.
This much need server upgrade will allow the game server to update three times more frequently allowing much less inputs lag, and the game will feel much more responsive.
When we implemented the “High Bandwidth” option to Custom Games back in beta, we also noted that—if the feature performed well and players responded positively to it—we would investigate adding it to other games modes. We’re holding to that promise and 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.
So what does that mean? 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 plans on adding a bandwidth control option to the game, which will allow players who have bandwidth limits to self-limit their update rates if they wish. This will come in a future update. Blizzard is currently working on to increasing the tick-rate of the console versions of Overwatch.
Since we know that not all internet connections are equal, we’ve also added in tech that will automatically and adaptively scale down your update rate if we find your connection can’t keep up. Similarly, because high bandwidth servers (as the name suggests) will increase your bandwidth consumption, we’re also looking to add an option to self-limit your update rate in a future patch.
