Blizzard is currently in the process of upgrading the Overwatch servers to run at 63Hz but what does this mean? If you are familiar with first-person shooter games then response time will mean a big thing to you. The servers used to be 21Hz meaning the servers were making 21 communications a second to everyone and back, moving the servers up to 63Hz means the servers and clients will communicate 3 times as much. Getting shot around a corner will be less likely to happen, you will not have to lead your shots as much and inputs will feel a lot more responsive.
The servers were originally set at 21Hz to prevent any crashing when the servers were first launched. 63Hz has been available but only exclusive to Custom Games, the change of the servers won't be affecting the esports scene at all because they have been competing on 63Hz servers. It will change the experience for matchmaking players.
While you may not notice it as much in the beginning, I'm sure you will eventually. In the Counter-Strike: GO scene, the matchmaking servers are at 64Hz (or tick) but there are also premium servers that run at 128tick. These 128tick servers are the standard when it comes to competitive play. Higher tickrate usually means the skillcap is higher, this awards faster reaction. It would be very unlikely for a game like Overwatch, which implements abilities rather than just gunplay, to need a server running at 128Hz but hey, I'll take the 63Hz. Matchmaking in Overwatch should be a lot more enjoyable and snappy now.
