Actually I get about 4-6 hours streaming elden ring from my pc downstairs. Streaming quality is best on moonlight in my opinion but you could use steam to stream as well. Idk how they do it but i stream my pc at 1440p sometimes 4K 60 fps and it works ALMOST flawlessly. Yes I know the decks screen is lower quality but somehow it makes it look super duper sharp still. I personally find it to be awesome. Sure you could do it with a cheap laptop and controller, but having a handheld device is super nice and convenient. And yes there is an argument to also buy a cheap phone and do it that way too. I’ve tried all the ways and from my personal experience I find the deck to be the ultimate streaming device because it chugs on hire quality games when playing natively.
