Windows' PC Gaming Grip Loosens Amidst Linux Surge
2 May
Summary
- Linux's PC gaming share grew from under 1% to over 5% since April 2021.
- Component shortages and AI chip demand delay Steam Machine and Steam Deck availability.
- Microsoft is internally working on 'Windows K2' to improve OS reliability and gaming performance.

Valve's SteamOS has achieved notable success in challenging Windows' long-standing dominance in PC gaming. Since April 2021, Linux's share on Steam has grown from under one percent to over five percent. This progress is largely attributed to Valve's strategy of enabling Windows games to run on Linux via compatibility layers, rather than relying on native ports.
However, recent global supply chain disruptions, particularly the demand for components by generative AI chip manufacturers, have severely impacted Valve's hardware initiatives. The company has faced significant cost increases and supply shortages, leading to indefinite delays for the Steam Machine and rendering the popular Steam Deck largely unpurchasable. This has also affected third-party handheld makers, potentially slowing the adoption of SteamOS.
In response to ongoing challenges and a competitive landscape, Microsoft is reportedly undertaking an internal initiative called 'Windows K2.' This effort focuses on improving Windows' reliability, performance, and security, with a specific emphasis on enhancing gaming performance to rival SteamOS. Microsoft is also working to reduce ads and streamline its operating system, including the rollout of its controller-centric Xbox Mode to all Windows 11 users, aiming to retain gamers on its platform.
