Been doing quite a bit of in-home streaming from PC to Steam Deck lately, and decided to give Chiaki4Deck a try for PS5 to Steam Deck in-home streaming. Works like a charm; great graphics (including HDR), touchpad and haptics support, and QoL stuff like sleeping your PS5 when exiting the Steam Deck’s stream session.
Here is the guide I used: https://streetpea.github.io/chiaki4deck/setup/configuration/
What’s the latency like?
My PS5 is wired, and my SD is the only device on the 6GHz WiFi I have up. So, imperceptible! I can count a handful of times I noticed input lag or stutter, that’s it. It’s basically cloud gaming, but sitting upstairs from the server.
I would also say imperceptible. The 2 critiques I have are that the audio can sound compressed through headphones, and there’s sometimes a spike in lag that happens around 20m in during some sessions. If I just disconnect and reconnect without putting the PS5 to sleep (usually a <10s process), it never happens again during even long sessions.
