Linux has evolved significantly in the gaming sector, becoming a credible alternative to Microsoft for PC gaming, aided by tools like Proton and a dedicated community. However, challenges remain, such as compatibility issues and a lack of native Linux game versions. The introduction of DirectX by Microsoft solidified Windows as the primary gaming platform, creating a focus on Windows that disadvantages Linux. Proton allows many Windows games to run on Linux but does not create native versions, and essential software for graphics cards is often missing. Currently, Windows holds over a 95% share in the Steam hardware survey, while Linux accounts for only 2.69%. Despite progress, Linux still faces a long journey to become a mainstream gaming platform.
