Man, I had such high hopes for Stadia. I was an SRE at Google when it was being built and knew some of the traffic folks working on the networking parts of it. Some of the absolute best people. Such a shame.
I’d never have considered adding WiFi to the controller to _reduce_ latency, that’s absolutely wild. Thanks for sharing!
I'm not sure why you'd find it wild. Any gamer with decent tech knowledge never buys Bluetooth wireless devices (mouse kb headset etc) for gaming precisely for this reason. Sites like rting measures latency for the same reason.
Gamers know about bluetooth latency when specifically compared to wired peripherals, and in that case I think that's intuitive. The counterintuitive part is that WiFi – a much more complex spec, plus all the IP stack, connecting to web services from a small low powered device, etc – is faster than a "simple" bluetooth connection designed for such devices.
