Valve quietly took another big step in its plan to change how we play PC games. 

This week, they added a new compatibility rating for Steam games that run on devices other than the Steam Deck. 

That might sound small, but it’s a big signal: Valve is gearing up to make SteamOS more than just the Deck’s operating system. 

It wants SteamOS to be the go-to PC gaming OS. And with the way Windows is going, that might actually work. 

SteamOS – From Side Project to Real Player

When Valve launched the Steam Deck in 2022, it came with SteamOS pre-installed. 

Back then, most people saw it as a Deck-only solution – a weird little Linux-based system with a funny name that made a handheld work. 

But now Valve’s trying to ensure SteamOS can run on any device, not just the Deck. Think gaming laptops, desktops, mini PCs, and even other handhelds. 

The new compatibility tag added to Steam will tell you how well a game works on ‘SteamOS, not on Deck’ setups. 

It’s a subtle change, but Valve is ready to support players building their own Linux-based PC gaming rigs. It’s not just about hardware anymore – Valve wants to own the whole ecosystem. 

Windows 11 – The OS Nobody Asked for

Timing, as they say, is everything. Windows 10 is reaching end-of-life in 2025, which means no more updates unless you pay up. 

And Windows 11? It’s bloated, loves telemetry, and keeps pushing users into Microsoft’s cloud services whether they want them or not. Gamers haven’t exactly embraced it. 

What’s worse is that many older PCs can’t even run Windows 11 without jumping through hoops. 

You’ll need a compatible TPM 2.0 chip, Secure Boot enabled, and often a relatively recent CPU. 

And if your hardware doesn’t meet these strict requirements, you’ll have to mess with registry hacks or unofficial installers just to get it working. 

Meanwhile, SteamOS is becoming lighter, faster, and more compatible with each update. Windows now feels bulky and overcomplicated for gaming, while SteamOS is streamlined, efficient, and built for play. 

Proton Is the Secret Sauce

A few years ago, gaming on Linux was like trying to ride a unicycle on a gravel road – technically possible, but mostly painful. 

But Valve changed all that with Proton. It’s a compatibility layer that lets you run Windows games on Linux and performs impressively well. 

Players are saying most single-player games just work. You install them, click play, and boom – you’re in. The exceptions are mainly multiplayer games that rely on invasive anti-cheat systems like the ones used in Valorant or Call of Duty. 

These systems, like Riot’s Vanguard and Activision’s Ricochet, operate at the kernel level – meaning they have deep access to your computer’s core functions. 

That level of control makes them harder to bypass, but also raises serious privacy concerns and often clashes with Proton, which is why these games usually won’t run on Linux. 

But for indie games, RPGs, roguelikes, and story-driven titles, Proton is a dream. 

So now that Proton is good enough for everyday gaming, why bother with Windows at all? 

Why SteamOS Actually Makes Sense Now

SteamOS isn’t just a gamer-friendly version of Linux. It’s also a great way to keep older hardware alive. 

Since it’s built to run games efficiently, it doesn’t waste resources on background processes you don’t need. That means faster boot times, better performance, and less overheating. 

If you’ve got a mid-range gaming PC from 2018, SteamOS might give it a second life. And in a world where GPUs are still absurdly priced and RAM isn’t getting cheaper, that’s a real win. 

Plus, most non-gaming services today are cloud-based – think streaming, productivity, and communication tools – so you can access them from a browser without needing Linux-native apps.

And for developers, there’s another perk. SteamOS encourages cross-platform development. If more users adopt it, game studios won’t have to rely so heavily on DirectX or other Windows-only tools. 

The end result? Games that are easier to port, cheaper to maintain, and potentially more stable. 

Valve is Building a Platform, not Just Selling Games

For years, Valve has remained primarily a storefront. Steam was simply a place to buy games, and that was the extent of it.

But now, Valve is turning into something more like Apple – a company with its own hardware (Steam Deck), its own OS (SteamOS), and its own platform (Steam).

The shift toward platform ownership allows Valve to gain greater control over its ecosystem, enabling them to shape the gaming experience more directly. 

This move opens up more options for gamers, giving them greater flexibility, access to a variety of services, and a wealth of content, all while allowing them to make more informed decisions throughout their gaming experience.

Don’t want to use Windows anymore? Fine. Don’t want to buy a Steam Deck? That’s fine too. Build your SteamOS box, slap it under your TV, and enjoy a console-like experience with a PC gaming library. 

That’s a shift Microsoft should be nervous about. 

What Still Needs Work

Of course, SteamOS isn’t perfect. 

The biggest roadblock is still anti-cheat support. Many competitive multiplayer games don’t run on Linux because the anti-cheat software doesn’t play nice with Proton. 

Until Valve solves that (and they are working on it), Windows will still be required for certain genres. 

Valve has already worked with major anti-cheat providers like BattlEye and Easy Anti-Cheat to support Proton and SteamOS. Still, it’s up to individual developers to flip the switch and enable it in their games. 

That’s the current bottleneck – the infrastructure exists, but adoption is slow. But there is a path forward. 

If Valve can win over a few major game publishers or eSports tournaments, the floodgates might open. Imagine a world where CS:GO and Valorant run perfectly on Linux, and gamers no longer feel tied to Microsoft’s ecosystem. It’s not far-fetched. 

The Big Picture

So here’s the thing: Valve isn’t just building an OS. It’s building an escape route. 

Gamers frustrated with Microsoft’s direction now have a real alternative – one that’s free, fast, and focused on games first. The new SteamOS compatibility rating is a small update, but it hints at a much bigger shift. 

In the end, this isn’t about the Steam Deck anymore. It’s about making Linux gaming mainstream. 

Valve’s not shouting about it yet. But it’s coming. And when it arrives, it won’t just change how we game – it’ll change who owns the future of gaming. 

So go ahead, Windows 11. Keep adding bloatware. SteamOS will be over here doing squats, waiting to take your crown.
