Millions of gamers have access to SteamOS through Steam Deck devices, which may struggle with demanding titles like Half-Life 3 at peak settings. Valve's games typically perform well on lower-end systems. Recent leaks indicate that third-party manufacturers are preparing to launch desktops, laptops, and handhelds with SteamOS, and a more powerful "Steam Deck 2" may be in development. The Lenovo Legion Go S will be the first non-Valve hardware officially "Powered by SteamOS." There is speculation that a timed exclusivity for Half-Life 3 on SteamOS could attract players to the platform, while Valve might also consider offering a non-exclusive version as a pre-installed title with future SteamOS iterations. This situation presents Valve an opportunity to challenge Microsoft's dominance in the PC gaming OS market.
