Want to know how much of your own Steam Library is currently compatible with the Steam Deck? Well, there's now a website dedicated to doing exactly that.

It's called CheckMyDeck (great name) and all you need to do is grab your SteamID, enter it and it will do all the work for you. You can find your SteamID easily using this other website. The main thing to keep in mind though, is that compatibility is an ever-changing thing, with Valve adding to the list almost daily. We mentioned only a few days ago how Verified + Playable together hit 520 games, well as of right now it's already jumped up to 591!

As for CheckMyDeck, it's pretty good actually. Giving you a full list with links to each store page, along with a very tidy looking pie to give an overall score:


A slice of my own status right now.

Another big thing to remember is that a game being Unknown doesn't mean much - it just hasn't been tested yet, and so it might end up being a flawless experience.

So basically you can expect 10% of your games totally unsupported and more than 50% fully enjoyable.
Not bad!
AussieEevee Feb 15, 2022
Mine is 4% xD

But 92% is marked as unknown, which as you said doesn't mean anything.

If you check the "unsupported" list, you find that the bulk of it is either VR or anti-cheat.

This may become more useful as more games get listed, but for now ProtonDB is still the way to go.

I'm looking forward to see the coloured section grow. :)

red coloured?

i have:

VERIFIED: 22 games (2.82%)
PLAYABLE: 25 games (3.21%)
UNSUPPORTED: 5 games (0.64%)
UNKNOWN: 727 games (93.32%)

I wish we have something like this with ProtonDB, as it can be annoying asking them to log-in to ProtonDB (I myself rarely log-in as I often distro hop and too lazy to log-in all the time).

Heck, I'd be very happy if the site also pulls from ProtonDB. It'd be an easy way for me to show to my friends that their Steam library is fine on Linux.

For now, mine is:

VERIFIED: 29 games (5.86%)
PLAYABLE: 18 games (3.64%)
UNSUPPORTED: 5 games (1.01%)
UNKNOWN: 443 games (89.49%)

Of the unsupported, they are: Bless Unleashed (EAC - Bronze), Hellblade: Sanua's Sacrifice VR (VR - Platinum), Insurgency (BattlEye; Native ver. seems to run w/ tweaks but also runs on Proton Exp. as well), Just Cause 2 (Needs Protontricks/ProtonGE - Silver) and Moero Chronicle (Video codec issues, no working tweaks so far - Silver).

I'm surprised that they're even evaluating the ecchi game as well. Steam likes to act like they don't have a big porn and risque library in their catalogue with fairly random enforcement.

7% are verified or playable from my library at this moment.

I have 32 games that are flagged unsupported. 30 of those were either VR (most) or anti-cheat.

I neither do multiplayer (anymore) nor VR (yet). I don't expect too much red. :)

Most of my library shows up as unknown, with 9% showing as Playable+

VERIFIED: 95 games (5.67%)
PLAYABLE: 53 games (3.16%)
UNSUPPORTED: 12 games (0.72%)
UNKNOWN: 1516 games (90.45%)

VERIFIED: 45 games (5.13%)
PLAYABLE: 35 games (3.99%)
UNSUPPORTED: 20 games (2.28%)
UNKNOWN: 777 games (88.6%)

Not exactly ideal, but at least "unsupported" is the smallest percentage ^^
Nice site for sure!

I suppose the lack of red indicates my lack of interest in multiplayer games...

I did expect more green though.

93% of my steam games are not even verified

Although, I'm a gog user I do buy games on steam with most of them being free.

But I hope Wreckfest is, atleast playable if not verified?

Out of all the Dead Risings games I have, the only one I don't have which is DR4 is the only one verified so far.

Really annoying!
Anza Feb 15, 2022
I got my first unsupported game: Hellblade: Senua's Sacrifice VR Edition

Could possibly be the only one, but sometimes it's hard to remember everything that's in the library

I don't buy VR only games, so that must have been bundled with Hellblade. I don't buy multiplayer games as such either, but there's always possibly that there might be one that I have bought for single player.

The vast majority of games for your average person's library is going to be "unknown" until valve's staff have time to extensively test all the 10s of thousands of games in the steam catalogue (10,263 according to google).

They didn't really start providing this public catalogue until a month ago, and this part of the effort isn't a community effort; only valve staff are testing and documenting game status (and probably only a handful at that). it's going to take time.

I don't know exactly how many staff they have testing these games, but just to give you some idea of the scope of the project: if valve have 5 ppl testing games for 8 hours a day straight, and they spend 1 hour testing each game, it would take them about 9 months to test every single game (roughly 40 games per day).

however, that does not take into account parallel efforts to get games into a playable state. as games are being tested, the testers are likely leaving notes for proton devs (who may or may not be the same ppl). the same games might be tested multiple times as updates to either proton or the games themselves are released.

Between 2022/02/04 and 2022/02/15, valve have gone through 471 games, at an estimated rate of roughly 42 games per day (including weekends). while we can't know for sure the actual testing rate, my example doesn't currently seem too far off. we'll have a better idea as valve test more games.

Quite exactly one year ago the Steam store reached 50,000 listed games. ( https://www.pcgamesn.com/steam/total-games )
It counts over 200,000 AppIds ( SteamDB ), this number includes DLC, software, betas, public test builds/servers, internal and press releases, removed games (due to licensing or regulations games are removed from sale, such as Rocket League) etc etc

And as for the staff: Valve only counts 360 employees which is nothing compared to EAs 11.000, Ubisofts 18.000, Sonys 110.000 or Microsofts 180.000
So there you have it, that's why they are rather slow and unresponsive.

64,364 today. It'll be more tomorrow. That's just games; there's DLC and non-game software, too.

VERIFIED: 14 games (8.59%)
PLAYABLE: 15 games (9.2%)
UNSUPPORTED: 0 games (0.0%)
UNKNOWN: 134 games (82.21%)

Up to 18% playable+, from 14% yesterday.

Valve have explicitly said they're hiring people to help with this verification process. While I'm sure they'll have some permanent employees continuing to monitor the steady trickle of games coming in into the future, for this first Herculean effort I wouldn't be at all surprised if they simply hired a few hundred contractors for a few months (using the money from TF 2 cosmetics, or some other rounding error in their budget) to get through the initial push. It's an eclectic selection of games right now, and slow, because they're testing a wide variety of things and shaking out the UI, but I've no doubt that in the next week and a half leading up to February 25 the flood gates will open and we'll see thousands of games ranked which they're probably sitting on right now.

Also by stretching it out rather than just saying "Here are 5k games that are at least playable" they encourage people to get invested and keep coming back to see if a game they want to play has been listed yet.
