text: 2017-present On August 22, 2018, Valve released their fork of Wine called Proton, aimed at gaming.  It features some improvements over the vanilla Wine such as Vulkan-based DirectX 11 implementation, Steam integration, better full screen and game controller support and improved performance for multi-threaded games. It has since grown to include support for DirectX 9 and DirectX 12 over Vulkan. The itch.io app added its own Wine integration in June 2020, while Lutris and PlayOnLinux are long-standing independent solutions for compatibility wrappers.
  As with Wine and Cedega in the past, concerns have been raised over whether Proton hinders native development more than it encourages use of the platform. Prodeus dropped native support in favour of Proton shortly before final release and Arcen Games cancelled planned native support for Heart of the Machine. Valve has expressed no preference over Proton or native ports among developers.
  On February 25, 2022, Valve released Steam Deck, a handheld game console running SteamOS 3.0. The deployment of Proton and other design decisions were based on the limited response to their previous Steam Machines. Linux was also used as a base for several nostalgia consoles, including the Neo Geo X, NES Classic Edition, Super NES Classic Edition, Sega Genesis Mini, Intellivision Amico, Lichee Pocket 4A, and the Atari VCS. It also powers the more general Polymega, Anbernic RG351 and 5G552, as well as the Game Gadget, Evercade, VS, EXP and Super Pocket retrogaming consoles by Blaze Entertainment.
