This channel analyses several online games and how they work networkwise. It seems online games typically "tick" at 30-60Hz in that the game server and user application communicates this often. 60Hz seems to be the "golden standard", and I guess resolution of 17ms is fine for when things are happening.
In gaming they have multiple delay components, one is "input delay" which relates to the time it takes from you for instance press the mouse button, until the game shows that it has responded by showing you result on screen. It seems this is typically 40-60ms, because the game needs to handle the input, send data to the graphics card, which needs to render it, and then it needs to be sent to the monitor. There are of course a lot more than this, but you get the idea.
I don't know what the delay is from mouse-click to when the game knows you clicked, and then can send out this information to the game server, but from what I'm guessing from reading up on the topic, this is in the "less than 10ms" range. So theoretically, the game can send an update to the game server much quicker than it can display on the local screen.
Another data point for instance for the game "Rocket League", is that the highest ranking players have a hard time playing effectively when the user-to-game server "ping" is more than approximately 100ms. I don't know if this is RTT, but considering they're getting around 130ms from a user in Texas to a server in Europe, it seems reasonable that this is RTT.
My reason for bringing this up (again) in the bloat forum, is that these people are exactly the kind of people who are very sensitive to problems that "anti-bloat" solves. If we can come up with a solution that makes it less likely that these people will get "ping spikes" etc, and we can package up something that actually solves this (preferrably something they can go to the store and buy outright), this would be a great way to "market" it. I'm quite sure they'd be interested in making videos about it to make more people aware of the problem.
There are multiple "gaming routers" out there, with "QoS". I have no idea what this "QoS" does. If anyone knows, I'd be very interested in knowing more.
