Over the past few years, the gaming world on Linux has undergone a true revolution, largely thanks to the constant improvements that Valve has implemented in Steam and, especially, in its famous compatibility tool: ProtonIf you're a Linux user or have a Steam Deck and have ever wondered how to run games designed just for Windows, chances are you've heard of Proton... and if not, you're about to discover why it's now easier than ever to play games without worrying about complicated settings.
Until recently, enabling Proton on Steam required a few steps and some tuning to run those Windows-only titles. However, with the latest series of updates released by Valve for both Steam Desktop (PC client) and SteamOS and Steam Deck, things have changed drasticallyNow, by default, Proton is enabled for all games that don't have a native Linux version, removing barriers and making it easier for those looking to expand their library without limits.
What is Proton and why is it so important for Steam on Linux?
Proton is a Compatibility layer developed by Valve that allows Windows games to run on Linux systemsIt works by integrating technologies like WINE and DXVK so games run almost natively on your favorite Linux distribution or on devices like the Steam Deck. This tool has become a cornerstone for those looking to enjoy Steam's massive library without being tied to Windows.
The fundamental change: Proton activated by default
Until the update ,launched By the end of June 2025, Steam users on Linux had to manually enable the option 'Enable Steam Play for other titles' so that Proton would work with all games that didn't have a native Linux version. This option was somewhat hidden in the settings and generated a lot of confusion among both novice and experienced users, as it was common to miss the button to install a Windows game if you didn't activate it.
With the new stable version of the Steam client, Proton is automatically enabled For all titles that don't have a native version, eliminating the famous tick box and making the experience much more transparent. This way, any user will be able to install most Steam games directly, without having to search for lost options in the settings menu.
Immediate advantages of this integration
- Ease of use: No more searching through settings. Just install your game and you're ready to go.
- less confusion: New users will not encounter the problem of not being able to install Windows titles.
- Continuous improvement: By being integrated from the ground up, Valve will be able to fine-tune and improve the compatibility experience more quickly and centrally.
Now the Steam's Linux compatibility page has been simplified to the maximum: you will only see an option to choose the default Steam Play tool, making it even easier for advanced users who want to experiment with other versions of Proton or alternative tools.
