How to Add Proton Compatibility to Run Windows Games on Linux with Steam

Introduction

For years, Linux users struggled with running popular games because most were designed exclusively for Windows. That changed when Valve introduced Proton compatibility in Steam. This tool bridges the gap, allowing gamers to launch and play Windows games on Linux almost as seamlessly as on Windows itself. By enabling Proton and optionally using Proton GE, you can expand your library and enjoy modern gaming without leaving Linux.

Understanding Proton Compatibility

Proton is a compatibility layer built on top of Wine, optimized for gaming. It translates Windows system calls into Linux-friendly instructions, ensuring your favorite titles run smoothly. Steam has integrated Proton directly into its client, meaning you don't need to configure Wine manually.

Steps to Enable Proton in Steam

1. Open Steam Settings

Go to Steam → Settings → Compatibility. Here, you'll find options for Steam Play, which powers Proton.

2. Enable Steam Play for All Titles

Check the box “Enable Steam Play for all other titles.” This ensures every Windows game in your library has the option to run with Proton.

3. Choose a Proton Version

Select the latest stable Proton release. For advanced compatibility, consider installing Proton GE, a community version updated more frequently for tricky games.

4. Force Proton for Specific Games

Right click a game in your library.
Go to Properties → Compatibility.
Enable “Force the use of a specific Steam Play compatibility tool.”
Pick Proton or Proton GE from the list.

Testing and Optimizing

Once enabled, launch the game. If you encounter issues like crashes or missing audio, try switching to another Proton version or Proton GE. Tools like ProtonDB can help you check how well a game runs on different Proton builds.

Conclusion

Adding Proton compatibility to Steam is the easiest way to run Windows games on Linux. With just a few settings, you can unlock a larger gaming library and enjoy smooth performance. For even greater flexibility, Proton GE provides additional fixes and enhancements. With this setup, Linux gaming is no longer limited it's thriving.
