SteamOS

SteamOS is Valve's Linux-based operating system that powers the Steam Deck handheld gaming device and serves as the foundation for expanding PC gaming to alternative hardware. Originally developed to deliver a streamlined gaming experience on portable hardware, SteamOS represents Valve's effort to move beyond Windows-dominated PC gaming platforms.

Valve is now partnering with major hardware manufacturers including Intel and Nvidia to expand SteamOS beyond the Steam Deck to additional PCs and devices. These partnerships focus on broadening hardware compatibility, particularly by building native graphics support for a wider ecosystem of components. The expansion positions SteamOS as a viable alternative platform for both portable and living-room gaming, demonstrating Valve's commitment to establishing a hardware-agnostic gaming environment independent of traditional operating system constraints.
