From the system requirements page: "GeForce NOW requires at least 15Mbps for 720p at 60fps and 25 Mbps for 1080p at 60fps."

I'm pretty sure I could get that most days even though I live out in the boonies, but it looks like Linux isn't a supported platform and GOG isn't a supported storefront. That's kind of a bummer.

On Google Stadia, games run on a server on an edge node close to you to minimise the latency impact. Google can afford this, as they have server capacity around the world.

But yes, latency does affect and may be a deal breaker for.some games.

There is some latency but I had no big issues playing strategy games and RPGs on my laptop.

The best part is that your Steam saves sync and the laptop stays cool.
