I usually play on Chromecast with stadia controller and it had been working great with unnoticeable lags. My network setup hasn't changed either and I usually don't run anything other than stadia for the sake of bandwidth. Connection has always been okay , and passed the speed test on stadia website. However, these few days the controller started to act up. Input lags are a few seconds, making most of games unplayable. At least on destiny 2 and tomb raider which I have been playing. Anyone shares the same experience and any help?
@GAPGAP I personally have not experienced what you're describing. I play almost everyday on the Chromecast with the controller.
You can try factory reset your controller and set it up again, hope that'll resolve it. https://support.google.com/stadia/answer/9584135?hl=en
at least not really on my side. Playing in Germany, 150Mbit/s connection. No issues in regards to latency, input lags, etc. at all.
Last time I played was on Sunday, so no information from my side if something is going in since this week.
Fingers crossed that you get your issues resolved.
