SteamOS 3, developed by Valve, is the operating system that powers the popular Steam Deck — and in 2025, it has become a go-to choice for desktop and console-style PC gamers alike. Built on Arch Linux and designed around Steam Big Picture/Game Mode, it offers a truly console-like experience on Linux.
Performance for Gaming
SteamOS 3 is optimized for performance and low-latency input. With Proton deeply integrated, users can play thousands of Windows games seamlessly on Linux. Updates and drivers are handled by Valve, and the Game Mode UI puts all your games front and center with minimal distraction.
User Experience
Unlike traditional desktop distros, SteamOS 3 boots directly into Steam’s Gaming Mode, bypassing the desktop entirely (though Desktop Mode is still available for advanced users). This makes it perfect for couch gaming setups, HTPCs, or anyone who wants to turn their PC into a console.
Pros:
- Official Steam support and updates
- Console-like experience out of the box
- Excellent Proton & controller support
- Rolling-release Arch base for latest packages
Cons:
- Not suited for non-gaming productivity
- Limited customization for desktop users
Final Verdict
If your PC is primarily a gaming machine and you want a no-fuss console experience, SteamOS 3 is the ultimate pick in 2025. Backed by Valve, it’s built for gaming from the ground up — and it shows.
