They have been doing it for many years now…
The device looks cool. And Proton works really well. When it works.
But not all the Windows only titles work under proton, and I think people buying a mainstream device like that, might not realise.
As in, one bit of publicity indicated/implied “peoples entire steam library available” and that’s not quite the case. Let alone after updates
[edit: I guess some might play over steam play, it does nto specify all games will play locally…
“Once you’ve logged into Steam Deck, your entire Steam Library shows up, just like any other PC.”
And I guess also it is a niche product, less than a million sales?]
Yeah, I’ve been using Proton for a while.
It’s good, but not without bugs.
I guess Valve believe it is production ready, and are betting on it.
This is the thing. the OS and hardware are all supported and maintained by Valve, which should mean it works.
What do you mean “let alone after updates”?
I’m curious about that too…
And like the existing compatibility, it’ll freeze it to a good set of files, like the current Ubunut 12.04 set.
It’s more the games not playing ball with updates
Proton/wine has a better track record with playing legacy games than Windows does my dude.
Legacy is less of an issue.
Older games (Probably) change less
It does look like a really nice machine though.
And Valve make the hardware, so they have far fewer variables to account for
Well, modern games are crap anyways. people who need the latest medal of battlefield 69 probably won’t be interested in this.
I was hoping that Valve can somehow make software devs to support anticheat on linux. I was hoping Steam Deck would be the one that would jumpstart most if not all AntiCheat software on Linux so i can play more games online.
I hope so.
I really like Valve, and they have done great stuff. And they are not afraid to try something on, give it a good go, and move on if needed.
I hope these machines take off
But but… I think I want to experience Battlefield crap for the first time? Not gonna lie, I kinda miss online competitive games, especially FPS, but I’d rather miss out on that than go back to Win10
Pretty cool little thingy. 
Is it just battlefield or multiple fps competitive games that dont work on linux? I’m in the midst of testing the waters of moving over part time
Pretty much all the online competitive FPS with no linux port uses BattleEye and Easy AntiCheat, meaning no:
PUBG
Fortnight
Overwatch
Apex Legends
Hunt: Showdown
Tarkov
All the World of MilitaryVehicles
All the Battlefields
All the Tom Clancy’s
All the Call of Duties
Insurgency Sandstorm*
ARMA 3*
*you can play online with a custom lobby that allows Linux/Proton but with disabled anticheat and consequently disabled public matchmaking.
My fear has also been MMOs such as Runescape that very quickly seem to assume macroing when you are on a non-windows based system, ie using proton or linux from the experiences I have read about.
It is getting better overall with compatibility, but still not quite there
In the press release didn’t Valve state that they are updating Proton to play nice with Anti-Cheat software?
I would assume “fixing” an issue such as that would require work on both the Valve side and the anti-cheat side in order to work together
They said they were reaching out to the devs directly to work with them on getting it working.
So, I wouldn’t buy into this with any real expectations of that coming to fruition I’m any time soon.
Edit: stupid phone auto correct
Ah, ok. Regardless I hope this pushes Steam to invest more and more into Proton and making it work better.
