Can I ask for those of you who have been using Sunshine (and specifically Moonlight) without issue - is there some part of your setup that you upgraded or had to troubleshoot specifically to get it to work well?
I have tried it on 802.11ax and with my Steam Deck, same household & router & network, and playing anything that requires a modicum of reaction timing was frustrating and inconsistent. I mean, 10ms or so of lag is playable, and 20ms could be in a pinch, but I was feeling rubberbanding into 50+, lag spikes, etc.
I've been using Sunshine/Moonlight for a couple of years now. Over wifi to my client device (NVIDIA Shield) it worked ok but would have a 0.5-1.0 second lag spike every few minutes. I tried all kinds of suggestions I could find but nothing properly fixed the issue. Besides that though the latency was fine enough.
Switching to ethernet resolved all issues and further improved the latency and it's been perfect streaming at 4K 60Hz. I've only ever done local streaming though.
Thank you. Seeing a theme here with ethernet. I do wish there was a reliable wifi solution, but I guess that's more than technology can deliver right now.
If ethernet to your main router isn’t doable, your workaround is to have a dedicated router connected to you PC’s ethernet port and broadcasting its own WiFi just for streaming.
My partner and I use this setup with pocket-sized travel routers for LAN parties so that we can use our Steam Decks and SFF PCs instead of moving a whole keyboard/mouse/monitor setup and requiring a desk.
I saw this suggestion, and it's pretty smart - This may be what I try next, next time I have the energy for it.
My biggest issues on wifi were random hitches and stuff. I'm on ethernet over coaxial now and it's basically flawless.
