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.

No it did not.
