Steam Deck debuted in early 2022 with SteamOS, a Linux-based operating system that uses the Wine-based Proton compatibility layer to run Windows games. This development has significantly advanced Linux gaming, with approximately 95% of games functioning well on Linux. Steam's Verified program lists nearly 9,000 Verified games, and around 30,000 playable titles, with only about 1% of popular games failing to run entirely. Anti-cheat systems remain a major limitation, preventing popular titles like "Fortnite" and "League of Legends" from being playable on Linux. Game streaming services like NVIDIA GeForce NOW offer alternatives for playing anti-cheat games on Linux. Linux distributions provide better controller support compared to Windows, particularly for handhelds and living room PCs. Accessing non-Steam games can be cumbersome, though tools like Heroic Launcher help. Compatibility issues with proprietary standards, such as HDMI 2.1 support, persist in Linux gaming.
