I wish industry encouraged engineers more to pay attention to this kind of things, rather than to flashy bells and whistles. 30-50ms may seem insignificant, but has a huge impact on the overall experience.

1ms is significant if you're a heavy user: https://www.youtube.com/watch?v=vOvQCPLkPt4.

From the video, 1ms feels real time, but with 5ms you can still notice the lag. So wouldn't it be more appropriate to say "4ms is significant"?

[amelius]

That would require a real-time OS, I suppose.

[gumby]

“Realtime” doesn’t imply faster. In fact often the opposite. It just means certain timing constraints will be satisfied, often making explicit what the costs (tradeoffs) are.

[amelius]

Yes, the constraint here is 1ms.

[jimktrains2]

You only need a real-time os if you're guaranteeing maximum latency.

[amelius]

Which is exactly what was asked for.
