On September 20, Valve made a notable move by updating a test application visible on SteamDB, revealing an extensive list of games undergoing testing with its Proton compatibility layer. Among the intriguing developments is the emergence of an ARM64 version of Proton, designated as “proton-arm64ec-4.” This version aims to facilitate the playability of Windows games on Linux, and it is currently being tested with hundreds of titles. Noteworthy among these are popular games such as Left 4 Dead 2 and Shadows of Mordor, highlighting the expansive potential that ARM64 Proton brings to the gaming landscape.
Expanding Horizons for Linux Gaming
While Valve has not yet issued an official statement regarding ARM64 support on SteamOS or for Proton, the indications suggest that this initiative is a priority for the company. It appears that Valve is keen on broadening its Linux gaming audience beyond just x86 hardware, aiming to incorporate Linux ARM devices into its ecosystem. This aligns with ongoing efforts to enhance gaming experiences on Windows for ARM platforms.
Additionally, there are mentions of Waydroid, hinting that even Android ARM devices might soon benefit from Proton support, potentially widening Valve’s audience significantly. Speculation has arisen that Valve could be developing its own ARM devices, possibly a more affordable alternative to the Steam Deck. However, this notion seems improbable, especially given the already competitive pricing of the Steam Deck. The introduction of a new, lower-tier ARM gaming device alongside the Steam Deck could complicate the market rather than simplify it.
Nonetheless, enhancing support for ARM devices aligns with Valve’s established commitment to fostering the Linux gaming community, particularly in contrast to the more restrictive Windows ecosystem. As the landscape of ARM gaming on Windows is still in its infancy, Valve’s advancements in Proton for ARM raise intriguing questions about the future of existing ARM devices, particularly those powered by high-end Snapdragon X chips.
Ultimately, as developments unfold, we may witness a Linux ARM gaming experience that surpasses the current offerings on Windows for ARM, a prospect that would undoubtedly delight Linux advocates. Presently, a significant number of games confirmed to function on Windows for ARM are already listed as undergoing testing by Valve, signaling a promising future for gaming on Linux platforms.
