Capcom shipped an update for Devil May Cry HD Collection on September 28, 2026, and the collection has since been reported to run properly on SteamOS and Linux. Capcom's own patch notes do not mention either one.
Three separate things could sit behind a change like this. A publisher patch, a Valve re-rating, or a fix on the Proton side.
Only the first of those is on the record. Valve's own listing for the collection still says the game does not work on SteamOS.
What Capcom changed on September 28
Capcom posted the update to the game's Steam announcement channel on September 28, 2026, at 08:45 UTC, tagged as patch notes. The body runs to two bullet points.
The first reads "Verified compatibility with Windows 11". The second reads "Miscellaneous bug fixes".
That is the whole notice. Capcom does not itemise what the bug fixes covered, and nothing in the text names SteamOS, Linux, Proton or Steam Deck.
The Steam listing now gives Windows 10 64-bit or 11 as the recommended operating system, which matches the first bullet. The minimum still reads Windows 7.
Capcom's own product page has not caught up. It still lists the minimum as Windows 7, 8, 8.1 or 10, and its page metadata records a last update of July 28, 2026.
Valve has not re-rated the collection
Valve's compatibility report for the collection, checked on October 3, 2026, still returns Unsupported. That verdict covers Steam Deck, SteamOS and Steam Machine alike.
All three carry the same reason, the one Valve uses for titles SteamOS does not support. Valve defines Unsupported as a game that is "currently not functional on Steam Deck".
There is no Valve blog post attached to the rating, and the field used for that link is empty. Steam Frame is a separate case again, with no rating published for the collection at all.
Valve does move ratings after a fix lands. It recently marked Dragon Age Inquisition as Playable following a Proton controller fix, and another Capcom title, Monster Hunter Wilds, reached Verified in August.
Valve does not publish a history of rating changes. The date this Unsupported verdict was applied cannot be established from the listing itself.
No Proton-side fix is on record
Valve's Proton issue tracker has carried an entry for the collection since July 12, 2020, and it is still open. It is filed under the label Valve uses for games not expected to work without issues.
The fault recorded there is a crash when cutscenes play, which drops the player out of the game. The entry does not name DRM, a launcher, anti-cheat or a missing dependency as the cause.
Its last recorded activity is December 25, 2023. No 2026 comment there says the game now works after a Capcom update.
Anti-cheat has never been documented as the blocker here. The collection is listed as single-player, and Valve shows no third-party DRM notice for it, although the store page does note that an internet connection is required for activation.
What the collection includes, and what is still unconfirmed
Devil May Cry HD Collection is a single Steam app holding three games. They are Devil May Cry, Devil May Cry 2 and Devil May Cry 3 Special Edition, the last of which includes the content that lets players use Vergil.
Because all three sit inside one app, Capcom's update reaches the whole collection. The notes do not single out any individual game.
There is no native Linux build. Steam lists the app as Windows only, Capcom lists the platforms as PlayStation 4, Steam and Xbox One, and anything running under SteamOS runs the Windows build through Proton.
The collection sells for $9.89 on Steam at the time of writing, down 67 percent from $29.99. The catalogue it would join on a re-rating is large, with more than 30,000 Verified and Playable games counted in September.
What those miscellaneous bug fixes actually changed is not published, and Capcom has said nothing about SteamOS. Valve has not commented on the update either, and has given no indication of whether or when it will retest the collection. Until it does, the store page will keep telling shoppers the game is not functional on SteamOS.
