SteamOS, a Linux-based operating system, appears poised for a major expansion into the PC gaming market. Rumors and code changes suggest that the OS will soon be available on all PCs, rather than just limited to specific devices like the Steam Deck.
This development is consistent with Valve’s previous announcements at CES 2025, where they revealed plans to make SteamOS accessible to third-party manufacturers. A Lenovo Legion Go S device, set to launch in May 2025, will be one of the first non-Valve-branded PCs to run SteamOS.
The move could mark a significant shift for Valve, which previously attempted to disrupt the PC gaming market with its Steam Machines initiative. However, this time around, SteamOS is seen as an optimized Linux alternative that leverages the portability and power of ARM chips.
Microsoft’s entry into the PC gaming space may be worth monitoring, particularly in relation to dual-booting capabilities. As more players enter the fray, including Nvidia with its ARM chip offerings, the stakes are high for this new landscape.
