I replaced Windows on my gaming handheld a year ago, and the industry caught up to me

Linux gaming has crossed a threshold where hardware vendors can no longer ignore it. Steam's Linux market share exceeded 5% in early 2026, partly driven by Windows 10's end of support. Lenovo put SteamOS on its flagship Legion Go 2 at $1,199, and benchmarks show SteamOS outperforming Windows 11 by up to 75% more frames. SteamOS 3.8 expanded third-party support to ROG Ally, Legion Go, and niche AMD handhelds, and the 3.8.7 beta adds Intel-based MSI Claw support, ending the 'SteamOS is an AMD thing' era. Proton's Direct3D-to-Vulkan translation now delivers near-native performance. Key remaining blockers include kernel-level anti-cheat (blocking Fortnite, Valorant) and Valve's outsized role in the ecosystem. The shift is now supply-side: vendors with spreadsheets are hedging toward Linux, making Windows-only the riskier bet for 2027 handheld SKUs.
