For example, the server does tick at 60Hz, it's the client update rate that is lower.

Yeah so increase the client update rate. Come on, Kaplan, you know what the interviewer is getting at...

You haven't seen a lot of shooters that move as fast as Overwatch

If that's what you think, it would be fair to expect servers capable of keeping up with that pace.

The other thing that we did, after that video, is we actually added what is called a 'high bandwidth option' to our custom games, that allows players to play at a 60Hz update rate. [...] It's kind of ironic that they're demanding it, it's in the game and playable, and right now we're seeing about 0.08 per cent of all matches that take place in Overwatch are actually using the feature.

Because when you use this 'feature', the server shuts down almost immediately due to errors, forcing you to play with a 20Hz client update rate anyway...

I've heard a lot of players say "god dammit, Blizzard, just add it to quick play". It would be wildly irresponsible for us to add that to something like quick play or competitive without getting more testing on the feature.

You don't need more testing. A higher update rate already works in other games, of which there are countless examples, and it is better than what you're currently using, period.

There was a great post/video about this a couple days ago correctly summarizing that, in Overwatch, players can only predict enemy actions, instead of react to them. When you think you've used a split-second ability in time to react to something, kill cam just shows "nope, never happened".

Don't get me wrong, I truly love this game, but that's exactly why I feel this could and should be improved.
