Windows 11 vs Linux vs SteamOS for Gaming in 2025

In 2025, PC gamers have more choice than ever when it comes to operating systems. Windows 11 remains the most popular and widely supported, Linux has become a serious contender with stronger driver support and Proton compatibility, and SteamOS has brought Linux gaming into the spotlight thanks to the success of the Steam Deck.

If you are planning a new gaming PC, the operating system you choose will define your experience. Here is how Windows 11, Linux, and SteamOS compare in 2025.

Gaming Compatibility

Windows 11 continues to dominate compatibility. Almost every modern PC game is designed with Windows in mind, and many use Microsoft’s own DirectX 12 Ultimate as the rendering backbone. Features like DirectStorage shorten load times by pulling data directly from NVMe SSDs, while Auto HDR improves visuals in older titles. For players who want everything to “just work” from Steam to Game Pass to standalone launchers, Windows remains the safe bet.

Linux has closed much of the gap. The Proton compatibility layer, which translates DirectX calls into Vulkan, makes thousands of games playable with little or no configuration. Valve’s work with developers has also convinced more studios to test their games on Linux before launch. Still, some titles, particularly those using invasive anti-cheat systems, may not run as reliably as on Windows.

SteamOS builds on Linux but is designed specifically for gaming. Its integration with Proton means that many games work right away without tinkering. At present, SteamOS is officially only available for the Steam Deck and other handheld devices. A full PC release is expected soon, and Gamertech will be offering SteamOS-based options once that happens. SteamOS is tailored for the Steam ecosystem, which means Steam games work best, although support for other launchers can require extra steps.

Performance and Drivers

Windows 11 gets the best driver support. NVIDIA, AMD, and Intel all prioritise their Windows drivers, releasing optimised versions for big titles on day one. The combination of DirectX and manufacturer-specific optimisations usually ensures consistent performance across hardware.

Linux performance has improved dramatically. With Vulkan maturing, Linux can sometimes match or even outperform Windows in supported games. AMD and Intel’s open-source drivers are particularly strong, giving excellent results without much setup. NVIDIA has improved its proprietary drivers too, though they are still slightly behind their Windows counterparts in polish.

SteamOS inherits Linux’s strengths but packages them in a user-friendly way. Valve curates updates, Proton compatibility, and drivers, making it easier to get consistent performance without the need to manually configure everything.

Features Beyond Gaming

Windows 11 offers the widest range of features outside of gaming. If you use your PC for video editing, streaming, 3D modelling, or VR, Windows provides native support for almost every software and device. Game Pass integration also gives access to a large library of titles without requiring separate purchases.

Linux is more modular and customisable. Users can strip the operating system down to run only what they need, which often means lower background usage and better efficiency. Security and privacy are also strong points, since Linux avoids much of the telemetry built into Windows. However, professional creative software like Adobe Premiere or Photoshop does not run natively, which can be a barrier for content creators.

SteamOS is focused entirely on gaming. It is less suited to productivity but works extremely well as a streamlined gaming environment. For now, its use is tied to the Steam Deck and handhelds, but its eventual arrival on desktops will give gamers a console-like option on PC hardware.

Ease of Use

Windows 11 is the most user-friendly choice for the majority of gamers. Installation is simple, most drivers are installed automatically, and almost every game launches without special setup. Even features like screen recording or game overlays are built into the OS.

Linux has improved but still requires more technical confidence. Different distributions offer different user experiences, with options like Ubuntu, Pop!_OS, and Fedora being popular with gamers. While tools like Lutris and Proton make it easier than ever to run games, troubleshooting is still part of the Linux experience.

SteamOS bridges the gap by making Linux gaming much simpler. Its console-like interface boots directly into Steam, with Proton integration ready to go. Advanced users can still access the Linux desktop if they want more control. For now, SteamOS is tied to handheld devices, but once it launches officially on PCs, Gamertech will offer prebuilt SteamOS systems for those who want a ready-to-play solution.

Cost

Windows 11 usually comes at a cost. A license can add around £100 to a new build unless it is bundled with a prebuilt system.

Linux is completely free and open source. This makes it especially appealing for budget builders or for people repurposing older hardware.

SteamOS is also free and maintained by Valve. Its updates are included, and no license costs are expected when it arrives officially for desktop PCs.

Which Should You Choose in 2025?

• Choose Windows 11 if you want maximum compatibility, reliable performance, and support for all major launchers, apps, and hardware.
• Choose Linux if you value control, efficiency, and open-source freedom, and you do not mind troubleshooting when something does not work.
• Choose SteamOS if you want a free, gaming-focused system with a console-like experience, especially if most of your games are on Steam. Desktop availability is coming soon, and Gamertech will be among the first to support it.

Final Thoughts

Windows 11 continues to be the most complete operating system for gaming, especially for players who value simplicity and guaranteed compatibility. Linux has become a serious alternative, offering strong performance and flexibility for those who enjoy customising their setup. SteamOS sits in between, delivering the ease of a console with the flexibility of PC hardware, even though it is currently limited to handheld devices.

In 2025, the choice is less about whether Linux or SteamOS can run games, and more about how much control and convenience you want. Windows remains the standard, but Linux and SteamOS are credible options that are only getting stronger.
