Linux gaming has gained popularity, especially after the release of Valve's Steam Deck, which shows that many PC games can run well on Linux despite not being designed for it. Proton, Valve's compatibility layer, allows Windows games to run efficiently on Linux without developer intervention. Most games lack specific Linux versions, but many Windows titles, including Elden Ring and Horizon: Zero Dawn Remastered, perform better on Linux through Proton, achieving frame rates up to 75% higher. Shadow of the Tomb Raider, which has a native Linux version, shows similar performance to those relying on Proton. Microsoft is reportedly using SteamOS as a benchmark to improve Windows gaming performance, indicating a shift towards aligning with Linux capabilities. Overall, gaming on Linux has become more accessible and enjoyable, often outperforming Windows.
