Do you mean Stadia? Stadia worked great. The only perceptible latency I initially had ended up coming from my TV and was fixed by switching it to so-called "gaming mode".

Never could figure out what the heck the value proposition was supposed to be though. Pay full price for a game that you can't even pretend you own? I don't think so. And the game conservation implications were also dire, so I'm not sad it went away in the end.

But on technical merits? It worked great.
