The State of SteamOS Compatibility, 2026

52% of 15,965 rated games hold a green Steam Machine verdict (8,274 titles), 1,564 struggle, and 6,127have no SteamOS signal strong enough to call. Verdicts are derived from Steam's own SteamOS/Deck compatibility plus a published spec model — not measured frame-rates.

The unrated share is the honest part of the picture: it is mostly the long tail of small releases Valve has never processed for Deck compatibility. We publish it as unknown rather than guessing, which is why the green share is a floor, not a marketing number.

Of 7,673 titles that declare a controller category on Steam, 66% (5,053) support a gamepad end-to-end and 2,620 are partial — meaning a keyboard is still needed somewhere. On a living-room console that gap matters more than frame-rate.

Steam declares this per game (categories 28 and 18); we harvested the whole catalogue rather than the popular slice, so the denominator here is every game that states a level at all. Titles that state nothing are excluded — absence of a declaration is not evidence of missing support.

201 games (2.1%) of 9,532 with a ProtonDB tier are community-reported as Borked — they do not run on Proton, the layer every SteamOS device uses. Platinum and Gold together account for 85% of rated titles.

These tiers are community reports shown verbatim — we never convert them into frame-rates. The Borked list is browsable at /collections/borked-on-steamos.

Across 8,224 games whose Steam page states recommended specs, 1,686 ask for exactly the Steam Machine's 16 GB of RAM and 119 ask for more. Only 803 state a VRAM figure at all — of those, 12 exceed the Machine's 8 GB and 99 sit exactly on it.

The interesting finding is the sparsity: fewer than one in ten games with published requirements state VRAM at all, so “will it fit in 8 GB?” usually cannot be answered from the store page. That is why our per-game answer treats a stated figure as a signal and stays silent otherwise rather than inferring one from a GPU model name.

1,434 games declare local or split-screen co-op on Steam and 2,876 declare co-op of any kind, out of 5,105 with a multiplayer category. 1,866 titles clear all three living-room bars at once: green verdict, full controller support and ProtonDB Platinum.

That last cross-section is the one no single source can produce — it needs Valve's categories, the community's Proton reports and a per-game playability call joined over the same catalogue. Browse it at /collections/couch-coop-steam-machine.
