Moonlight (moonlight-stream.org)

I use it to stream games from a PC to an XBOX ONE and also to a NVIDIA shield for a lean-back experience. With Steam Big Picture mode it is a great console experience though I did have trouble with latency for HiFi Rush over the wireless link to my fortress of solitude in the other house.

I love moonlight, I use an ipad with a gamesir controller for streaming from my ... perfect for passing the time while trying to get my 6 month old to sleep in his ergobaby.

I use this to stream my ROG Ally to my Vision Pro on long plane rides. The latency is crazy low.

Sadly only works for single user

Great project, unfortunately in my experience does not work from 4K display (Windows) to a 4K (macOS with external monitor). The image is blurry.

Maybe worth mentioning the ppen source server side component as well since it is unclear how long gamestream will continue to work? : https://github.com/LizardByte/Sunshine

Worked like a charm for me in 4k
