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.

Windows Pc Requirements

Minimum:

• Requires a 64-bit processor and operating system
  
• OS: Windows 11 (64-bit)
  
• Processor: 64-bit processor with SSE3 support (Most 2006 or later CPUs)
  
• Memory: 4 GB RAM
  
• Graphics: GPU with DirectX 10 support and hardware video decode for H.264 (Most 2012+ GPUs)
  
• DirectX: Version 10
  
• Storage: 3 GB available space
  
• Additional Notes: Software video decode works without hardware support, but uses significantly more CPU and is much slower, and is not recommended. Integrated graphics are sufficient for most use cases (1-6 tiles at 1080p).

Recommended:

• Requires a 64-bit processor and operating system
  
• OS: Windows 11 (64-bit)
  
• Processor: Quad-core processor or better (2014 or later CPU)
  
• Memory: 8 GB RAM
  
• Graphics: GPU with VP9 and HEVC hardware decode for best format compatibility (Most 2016+ GPUs)
  
• DirectX: Version 11
  
• Storage: 5 GB available space
  
• Additional Notes: Larger grids (7+ tiles) with FHD content benefit from dedicated GPUs.

Turn any monitor into a personal video wall. Arrange videos in custom grid layouts, shuffle through collections, and save everything as one-click compositions. Your videos, your wall, your Mosaiplay. No internet required.

Mosaiplay turns any monitor into a fully customizable video wall. Pick your videos, choose a layout, and let it play. No streaming services, no internet connection, just your local video library, displayed however you want.

PLAY MULTIPLE VIDEOS AT ONCE

Arrange up to 36 videos in a grid and watch them all simultaneously*. Each tile plays independently with its own controls for volume, shuffle mode, and video fit. Choose from 8 built-in layout presets, including Single, Split, 2×2, 3-Column Portrait, Picture-in-Picture, or design your own grid with the visual layout editor.

ORGANIZE WITH COLLECTIONS & COMPOSITIONS

Import video folders as collections and assign them to tiles. Save your entire setup, layout, collections, volumes, widgets, and shuffle modes as a composition and restore it in one click. Use Auto-start so Mosaiplay picks up right where you left off in the last session.

6 SHUFFLE MODES & TRANSITIONS

Go beyond basic shuffle. Choose from Sequential, Shuffle All, Shuffle Videos Only, Shuffle Collections Only, Repeat One, or Repeat Collection — and set different modes per tile. Pick from 6 transition effects (Fade, Slide, Zoom, Blur Fade, and more) with adjustable timing.

NOT JUST VIDEO, ADD WIDGETS

Mix utility tiles into your wall alongside videos:

- Clock with 12/24h format, timezone support, stopwatch, and countdown timer

- Text Notes for reminders, labels, or annotations

- RSS Feed Reader with auto-scroll and configurable refresh

Each widget supports independent font scaling and per-tile color themes.

DECOY BUTTON

Press B to instantly hide everything behind a decoy screen — a fake spreadsheet, a fake desktop, or your own custom image. Press B again to resume exactly where you left off.

PLAYS ALMOST ANYTHING

MP4, WebM, MKV, AVI, MOV, WMV, FLV — Mosaiplay handles all major video formats out of the box. Many incompatible files are automatically converted via bundled FFmpeg: no codec packs, no extra downloads.

BUILT FOR EVERYONE

- 3 color themes (Dark, Light, High Contrast)

- Color blindness filters (Protanopia, Deuteranopia, Tritanopia)

- OpenDyslexic font toggle

- UI scale from 0.5× to 3.0×

- 9 languages: English, Chinese (Simplified), Japanese, Korean, Russian, Spanish, Portuguese, German, French

- Fully rebindable keyboard shortcuts

WORKS OFFLINE. STAYS ON. KEEPS PLAYING.

No internet required for any feature (technically, you can have a local RSS feed ^_^). Mosaiplay prevents display sleep, so your video wall stays running, continues playback in the background, and auto-saves everything, layouts, playlists, compositions, and settings, so nothing is ever lost**.

The videos shown in screenshots are for demonstration only and are not included with the application. Mosaiplay plays your own local video files.

*The number of streams that can be played depends on your hardware.
