Confused on Steam Play and Proton? Be sure to check out our guide.

We've been wondering what Valve had planned to show off Steam Deck compatibility for games and now they've launched Deck Verified as their answer.

Valve say they are reviewing the entire Steam catalogue on the Steam Deck, with each of them gaining a category that it falls under that will show up across Steam from the store to your own Steam Library. The ratings will be split across Verified, Playable, Unsupported and Unknown. This is good because there's a lot of reasons why games will mix between perfect and unplayable on Steam Deck and the Arch Linux-based SteamOS it ships with.

To be actually Verified the games need to hit these four points:

  • Input - The title should have full controller support, use appropriate controller input icons, and automatically bring up the on-screen keyboard when needed.
  • Display - The game should support the default resolution of Steam Deck (1280x800 or 1280x720), have good default settings, and text should be legible.
  • Seamlessness - The title shouldn’t display any compatibility warnings, and if there’s a launcher it should be navigable with a controller.
  • System Support - If running through Proton, the game and all its middleware should be supported by Proton. This includes anti-cheat support.

When you're playing on a Steam Deck, the first tab in the Steam store will also only highlight games that are "great" on the Steam Deck too.

Valve also put up a Steam Deck Compatibility Review Process guide, which goes over the steps required for developers to take a look at. It gives an interesting insight into exactly what Valve and developers will be doing. Developers however will not be able to remove their game from being listed as Valve say the Deck is "an extension of Steam onto a new portable PC form factor, and so customers both expect and have access to the same store and library that they would on any other PC".

But it proves how random things are, even on Windows. The issue my son got, with this games, is largely documented on support sites... He is not alone. On my end, just turning on ProtonGE makes the game run. We have same spec computers (except for the GPU, both Nvidia though).
That's true for Linux users as well. A native game may or may not work on a given distro which is why Valve offers SLR (the Ubuntu container) because what Linux compat often means is just Ubuntu support. Proton doesn't work consistently either as you point out. You needed to install a Glorious Eggroll compile of Proton to make things work as intended. Gaming has always been like this since the days of DOS, Amiga, and OS2 before Windows and Linux.

You said, someone should test whether these things work on Win10/11 and then submitted a game you said doesn't work on Windows. I tested it, since someone curious asked, and it works for me. You know, like when you can't compile an app at work and the author shrugs and says, "It works on my machine."

It proves my point nonetheless... 100% compatibility on Windows doesn't exist. That's all I was saying. I never said it was better on Linux. Batman AA was just an example that I know is problematic for many Windows users. It works for you? Great for you!

If 90% of games are working on Linux being native or with Proton, it's probably in the same range than Windows games on Windows. We are not even talking about the fact that the Steam Deck is a dedicated hardware that will probably have more compatibility than any PC and it's millions of possible hardware combinations (software + hardware).
Windows users don't think games have 100% compatibility so I'm not sure where you got the idea that is a thing. Games age and stop working on newer OS versions just like Linux. I can tell you with absolute certainty that more games work on Windows overall and the experience is smoother, but there are some edge cases where they do work better through Proton. I don't think that's a great comparison or standard for Linux land to try and live up to. What's important is that the experience on Linux distros both through Proton and natively are satisfying. And most importantly for the Deck is that the games that are rated to play well do that, and I think they will.

Exactly what I'm saying from the begining. I realise that the Batman example just added some confusion to the discussion. My bad. Sorry.

Quoting: STiAT
Quoting: MohandevirBefore worrying about the 100% compatibility mark, I would try to get the same tests on Windows 10-11 with Windows games... It might be lower than 90%.

Ex: My son was never able to run Batman Arkham Asylum on Windows... I did with Proton.

I mean... 100% support doesn't exist, even on Windows, so...

The difference to Windows is that they target one hardware platform. Steam Deck has one hardware configuration. That's doable. They've hired external testers and are hiring for their internal team to get that curated and to provide (according to valve) verification within a week.

A week is nothing in the time of game development.

I'm actually not wondering if they can test 50.000 games. I am wondering if they have the means to improve then when they find out 20 % are not running properly, since that will very likely be more intensive, and having 10k games to improve is for sure no easy task for a small team as Valve is. Except if the original game developers help on that, either paid or on their own accord.

I'm seeing a lot of proton based updates to games (not proton itself, but the actual games updating), so I think that devs are actively working on making their games run on the deck. That's a good sign and will help us all (unless the new settings and improvements only work on steam deck).

There certainly seems to be a lot of interest in steam deck by developers. They probably do that with their existing titles to have the skills for their next title to come, but still that's interesting. Game devs hardly every showed any interest in that.

Yep! I really do think that game devs caring for the Steam Deck (which seems to be the case) is going to help compatibility for the games that got released in the last couple of years and for futur titles. Since it's a stable platform (one hardware and software target), it's going to be a lot easier for them to support. On top of that, Valve is taking on themselves the task of expanding the Proton compatibility for a maximum of desktop hardware configuration.

Quoting: mirvThat's what has me concerned: Valve aren't going to track all the games and update things themselves. They'll try outsource that to "the community" and basically do a bare minimum themselves (basic business I guess). And realistically, if a game breaks then people are not going to blame Valve.
Then if Valve try any kind of pressure or strong-arming publishers, I don't think that would work either. Epic would be more than willing to give extra incentives to any publisher that happens to. Valve will have to keep publishers on their side in this case.

You do realize that you are making a number of assumptions here. For all we know, the "Verified" tag won't go on anything without publisher approval. Valve sent publishers development kits for a reason. It's quite possible that "Verified" will be a status that is maintained by the publisher, while "Playable" will be maintained by Valve and the community or some other arrangement regarding who has responsibility for each tag will exist that we haven't thought of.

I hadn't actually assumed it - previously in the conversation was clear about if Valve were doing things without publisher/developer consent. With consent is another matter entirely.

the issue is that they promissed one thing, and then downgraded their promisse, what about people who alredy pre order one?
at least they paid only 5 dollars, and have to refund only 5, but i can see that not everone will be confirming their purchase at the last minute, and not everyone who purchase, will see this video before they confirm and get screwed...
I believe what they originally said was, they will consider any game that does not work on the Steam Deck a bug. They did not say that the Steam Deck would ship bug-free.

again, that was an retraction from their first message.

Quoting: elmapulagain, that was an retraction from their first message.

The way I remember their first message was that one hundred percent Steam compatibility* was their eventual goal for the Steam Deck rather than a "promise" of the state of things when the Steam Deck first shipped. Of course they should have known how people tend to hear what they want to hear.

*(Of course this would be with the obvious caveat of the form factor not being appropriate for certain games such as VR titles.)

actually, it might have been "playable"
but their definion of playable is not the same as verified...

VR exclusive games are always marked unsupported on the deck even if they could run perfectly on Linux or even on the deck's hardware. This is said explicitly in the valve video.

i'm not complaining about it, the issue is:
when they said their goal was everything will be playable at launch, i was expecting then to try to fix the remaining bugs.

the game works, but any game cutscene dont work , count as playable?
or the full screen dont work?
or the sound effects dont work?

Just happened to read something I haven't tought about... Could we witness the creation of a Steam Deck market place for game themed Micro SDXC cards sold with said game preinstalled on it? Might not be really ecologic, but it could be nice. The 64GB Steam Deck could greatly benefit from that.. The challenge would be to not lose them.

Just a tought.
