This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.
1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."
Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.
Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.
2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.
3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.
4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.
Command the silent service. Modern Naval Warfare is the definitive tactical simulation that puts you inside the pressure hull of a Virginia-Class nuclear submarine. This uncompromising tactical simulation offers unparalleled depth in graphics, physics, and authentic combat systems.
Command the most advanced nuclear-powered submarines in the world. Modern Naval Warfare is the ultimate tactical simulation, offering unparalleled depth in graphics, physics, and authentic combat systems. From the pressure-crushed depths of the ocean to the high-stakes politics of the South China Sea, every bolt, frequency, and sonar ping is simulated with uncompromising detail.

Unrivaled Visual & Atmospheric Fidelity Experience a world built on real-world GIS data. The simulation's physically-based rendering (PBR) and world lighting create a breathtaking environment, from the curvature of the Earth at high altitudes to the shimmering caustics and reflections on the ocean surface.
Volumetric Clouds & Dynamic Weather: Navigate through GIS-assisted weather conditions and a multi-layered spectral wave system.
Authentic Interiors: Explore accurate 3D representations of the Virginia class (Blocks I-IV) CIC with fully clickable, feature-complete control stations.
Living World: Engage with digital twins of modern military and civilian platforms, including dynamic civilian traffic assisted by GIS-AIS data.
Advanced Acoustic & Physics Simulation In the silent service, sound is your only sight. Our 3D sound propagation model calculates transients, flow noise, and individual component sounds (engines, pumps, propellers) in real-time.
Real-time Signal Analysis: Utilize FFT analysis for Narrowband, LOFAR, and DEMON applications, modulated by specific sonar array characteristics.
Physical Realism: Every object follows real-time hydrodynamic and hydrostatic calculations. Weapons movement, explosions, and even material reactions to underwater pressure are physics-based.
Damage Control: Face hi-fidelity damage modeling and volumetric flooding based on true shipbuilding concepts like permeability.
Sophisticated Systems & Weaponry Take control of a wide spectrum of military-standard sensors, including RADAR, SONAR, and EO/IR.
Electronic Warfare: Experience RF signal propagation affected by wavelength, line-of-sight, and antenna configuration.
Lethal Arsenal: Deploy torpedoes, multi-stage missiles (with individual stage envelopes), and mines.
Countermeasures: Defend your boat with noisemakers, sonar decoys, chaff, and flares.
Navigation: Use INS, GPS/GNSS, Tercom, and DSMAC for precision strikes.

Step into the role of various crew members with native-language station interfaces:
Pilot Station: Control depth, speed, course, trimming, and masts.
SONAR Station: Manage Broadband, Narrowband, Active Intercept, and Tactical Decision Aid.
Fire Control: Utilize advanced TMA (Target Motion Analysis) with interactive rulers and mission planners for Harpoon and TLAM missiles.
ESM & RADAR: Intercept threats and monitor AIS signals to maintain situational awareness.

Whether you are a lone wolf or part of a strike group, the world is your battlespace.
The Technothriller Campaign: A massive 18-mission campaign set in the South China Sea.
Diverse Operations: Engage in Anti-Submarine Warfare (ASW), convoy hunts, special forces insertion, and espionage.
Training & Editor: Learn the ropes with a 3-mission training sequence or create your own challenges with the built-in quick mission editor.
