I’ve gotten back into my Steam library because of NVidia’s GeForce Now service, but there’s a handful of games I own but can’t play because the publishers won’t let NVidia stream them. The most resource intensive game I’m interested in is probably Batman: Arkham City, though I’d also like to use Dolphin to emulate some older Wii/GC games. What I’d like to do is add to my stable of NUCs/NUC-like systems in my networking closet, and stream to my Shield TV. I tried doing this with my fastest NUC, which is still only a Pentium SIlver J5005; while it’s at least got QuickSync, my expectations were very low, and I got about what I expected. The encoding process ate up every available CPU cycle, and left nothing to actually run a game. Would something like this: https://arstechnica.com/gadgets/2021/04/mini-pc-review-the-ryzen-5-pro-2500u-powered-minisforum-um250/ do what I’m looking for? Anything else I should consider in the <$400 price range?

Also, AFAIK the only way to stream games to the Sheild from Linux is with Steam. Moonlight, Parsec, etc etc require a Windows PC. Any other streaming software worth looking at?
