Steam Deck lead reveals Valve is funding ARM compatibility of Windows games (frvr.com)

Valve, the company behind Steam, is taking significant steps to expand the compatibility of Windows games on ARM devices, as revealed by Pierre-Loup Griffais, the lead for Steam Deck and SteamOS. For nearly a decade, Valve has been funding Fex, an open-source project aimed at developing a compatibility layer that allows Windows games to run on ARM architecture. This initiative not only supports the ongoing transition of games to Linux via Proton but also opens the door for a broader range of devices—including low-power laptops, tablets, and potentially phones—that can support PC gaming without the conventional limitations of Windows. The move is particularly noteworthy for the AI and ML community, as it signifies a shift towards greater flexibility and diversity in gaming hardware. Griffais emphasized the efficiency of ARM chips over traditional x86 processors, particularly at lower power consumption levels. This aligns with tech industry trends favoring energy-efficient computing, particularly in mobile and handheld devices. While challenges remain—such as compatibility issues with certain games and the hurdles presented by anti-cheat systems—Valve's efforts could pave the way for a more robust ecosystem where gamers can enjoy their libraries on various platforms, further diminishing Windows’ longstanding dominance in the PC gaming space.
