Yeah, they mention here that Windows is the only officially supported platform but they do add some details for Linux users to try it out: https://help.steampowered.com/en/faqs/view/2668-0B6E-79E0-A85B#os

Point of clarification: for me at least, regular wifi based streaming from my linux computer works fine, with the typical caveats about latency or quality at times. It's the wireless dongle that has trouble, but if your home Internet is good enough then it isn't necessarily a dealbreaker. I've been able to stream some lighter stuff which, combined with the standalone options, satisfies me to tide me over until the dongle works properly.

The specs shown for the official charger are PD3.0 Type C power supply, 45W so I bet a decent power bank would work.

I did experience a little eye fatigue but nothing too crazy. When the battery ran out I still felt like I could have gone at least another hour.

I haven't had a chance to try it yet, but that one is officially supported so it should be fine. Planning on testing it tonight so I can let you know for sure later.

Update: it works great

I played it on mine yesterday and it ran perfectly fine. Still trying to figure out how to install mods for the game. Things are slightly complicated by the ARM architecture with compatibility.

It runs perfectly, best I can tell. I did have some setup issues streaming it from my computer. I wanted a repeat view for others to watch.

I'm in the US and really close to one of the places they ship from. I paid last Thursday when I got the email and they shipped on Monday. Got it the next day.

They seem to be going out in batches. I was lucky enough to get an early one in the UK.

Some people get simulation sickness so that's something to be aware of. If you do, I suggest stopping immediately when it happens and increasing time in sessions gradually. A cooling fan and light clothing can help as well.

I've never had an issue with that before, but I've only used the Vive. My eyes felt a bit dry after using the Frame for a couple of hours but I don't know if that's the same thing as making my eyes tired.

Not really. The biggest issue is motion sickness. A lot of games have you teleport around for that reason. I can personally handle it quite well, but some games still mess me up e.g. subnortica.

That said, some people do have eyes that are slightly off level with each other. That can cause interesting problems for them. It's not hugely common however.

I don't wear glasses, but I did get the ergonomic kit after seeing most reviewers say it's basically a requirement. I don't love the head strap so far but I may just need to adjust the fit. When I was using it yesterday it felt like I had to do extra work to get it to fit in a way that I could see clearly.

The bracelets are nice though and allow you to use the finger tracking more like the Index controller. It also comes with the improved plastic nose cover but I haven't installed that one yet. The one it comes with has been fine but there's a small gap.

Right now the regular SteamVR and the beta are the same version, but I do currently have it set to the beta. The issue is almost certainly the mesa driver. I installed some of the proprietary encoders but I have a feeling I'm missing something. Going to keep trying tonight but unfortunately there's not a lot of information on the requirements just yet.

Not near/far sighted so I can't really answer anything related to that. I did get the ergonomic kit and I'd recommend it, but I wouldn't call it unbearable without it.

The color vibrancy and contrast don't seem significantly different to me. The biggest difference is definitely the higher resolution and the lack of the screen door effect. To me, the higher resolution and removing the need to set up base stations were worth the upgrade but if you're happy with the Vive it's probably fine.

I can't imagine that is true anymore given that the Arch-based SteamOS can be officially installed on any AMD machine without any workarounds now.

I believe they have stated that Linux support just isn't ready yet, should be very soon

I haven't but I may try it out if I can't get the official streaming working. I've seen reports of 2D streaming working on Linux so it's likely something with my own environment. I don't know much about Moonlight but I guess my concern would be it working with the wi-fi dongle.

From what they have here it sounds like Linux streaming is still a work in progress: https://help.steampowered.com/en/faqs/view/2668-0B6E-79E0-A85B#os

Is moonlight/sunshine more performant than steam remote play on the steam deck?

I couldn't get the streaming with a dongle to work on my Linux install, but streaming over Wi-Fi worked perfectly fine.

I haven’t. My connection isn’t great where I have the Frame so I didn’t bother with it.
