An anonymous reader quotes a report from Ars Technica: We've known for months now that Valve is expanding its Linux-based SteamOS operating system beyond the Steam Deck to other handheld PCs, starting with some versions of the Asus ROG Ally. This week, Valve began making some changes to its Steam storefront to prepare for a future when the Deck isn't the only hardware running SteamOS. A new "SteamOS Compatible" label will begin rolling out "over the next few weeks" to denote "whether a game and all of its middleware is supported on SteamOS," including "game functionality, launcher functionality, and anti-cheat support." Games that don't meet this requirement will be marked as "SteamOS Unsupported." As with current games and the Steam Deck, this label doesn't mean these games won't run, but it does mean there may be some serious compatibility issues that keep the game from running as intended. Valve says that "over 18,000 titles on Steambe marked SteamOS compatible out of the gate," and that game developers won't need to do anything extra to earn the label if their titles already support the Steam Deck. SteamOS uses a collection of app translation technologies called Proton to make unmodified Windows applications run on SteamOS. This technology has dramatically improved SteamOS's game compatibility, compared to older SteamOS versions that required games to support Linux natively, but it still can't support every single game that Windows does. Valve says that the "SteamOS Compatible" label isn't meant to imply how well a game will run on the Steam Deck or any other SteamOS handheld but that this label is "just the first step." The company is "continuing to work on ways for people to have a better understanding of how games will run on their specific devices." of this story at Slashdot. #valve #takes #another #step #toward
