"There is not a native app on Steam deck today," said Andrew Fear, GFN boss, back in January. "Use a Chromium browser to make it work. I would say that both Nvidia and Valve, I think we're both interested in making [GeForce Now on Steam Deck] better. But we don't have any announcements on a native app coming to Steam."
Back when I had a 1060 3gb it was awesome! Always giving me nearly flawless settings for games, now with a 3060… we have very strong disagreements about the ideal settings.
That said yeah, a random software to install, that requires a new account and all for the privilege of installing the drivers? Hard sell.
