How long is the rest of the latency chain? For example, keyboard input over usb is gonna be ~15 ms, processing time is gonna be >5ms, and display time like 12ms

How long is the rest of the latency chain? For example, keyboard input over usb is gonna be ~15 ms, processing time is gonna be >5ms, and display time like 12ms. Adding those comes to a minimum of around 32ms. [1]
I'm not sure if I can tell the difference between 32 ms and 37 ms.

- 1_player 6y agoYour 37ms is based on 5ms roundtrip and 0 CPU time, which is impossible. And add network jitter which might be worse than static latency. And the Stadia market isn't people with fast monitors, Ethernet connected and ultra stable internet, but high latency TVs, avg tier Wifi, slow hardware to decode video.
- neolog 6y ago> 0 CPU time I meant to assume 5ms CPU time: 12 input + 5 processing + 15 output = 32. Add 5 for network round-trip to get 37. > 5ms roundtrip 5 ms network round-trip or less is common in offices or homes with fiber. Here's ICMP ping 1.1.1.1 from my office just now: rtt min/avg/max/mdev = 4.075/4.700/6.407/0.459 ms. (UDP wouldn't be so different.) Of course, on wifi or low-speed broadband it wouldn't be so fast. > high latency TVs High-latency displays makes network latency less noticeable relative to a conventional console game (but more noticeable relative to a PC game on a fast-updating screen).
