I do hugely recommend playing it on GeForce now instead. It works like a dream, you can max out all the settings, and you don't get locked into an ecosystem that Google will inevitably abandon in the next couple years. I've been playing Cyberpunk using it and have no complaints, very little if any lag on my 100Mbps BT line.
Every time I tried GeForce Now it put me in a long queue before letting me in. Never happened with Stadia and the whole "take up your controller and play" experience feels more polished on Stadia.
Hopefully we'll get ray tracing and maxed out settings with the next Stadia hardware upgrade.
