Is Steam Compatible with Steam Deck?
Introduction
The Steam Deck is Valve’s handheld gaming device running SteamOS, a Linux-based operating system. This article covers how the Steam platform and its game library function on the Steam Deck, including compatibility ratings and Proton support.
Key Takeaways
- Steam is pre-installed on the Steam Deck and works natively.
- Proton enables most Windows games to run on the Deck’s Linux-based OS.
- The Deck Verified program rates game compatibility with four tiers.
- Over 15,000 titles are rated Verified or Playable as of early 2026.
- Anti-cheat software remains the primary barrier for some competitive games.
Compatibility Overview
The Steam Deck was designed by Valve to run Steam games, and Steam is deeply integrated into the device. SteamOS provides a console-like interface (Gaming Mode) optimized for handheld use, with a full Linux desktop (Desktop Mode) available for additional functionality.
Windows games run through Proton, which translates Windows API calls to Linux equivalents. Valve’s Deck Verified program tests and rates games for compatibility, input mapping, display readability, and system support on the Steam Deck.
Supported Platforms and Requirements
- Operating System: SteamOS 3.x (Linux-based, pre-installed)
- Compatibility Layer: Proton (pre-installed, multiple versions available)
- Verified Games: 15,000+ rated Verified or Playable
- Storage: Internal SSD (64 GB, 256 GB, or 512 GB) plus microSD expansion
- Internet: Required for downloads, updates, and cloud saves
Known Limitations or Common Issues
- Games with kernel-level anti-cheat (e.g., VALORANT, Fortnite) may not function.
- Some games rated “Playable” may require manual configuration of controls or settings.
- Text-heavy games or those with small UI elements may be difficult to read on the 7-inch screen.
- Games requiring a mouse and keyboard may be awkward to play in handheld mode.
- Storage on the base 64 GB model fills quickly with modern game install sizes.
Alternatives or Workarounds
- Check ProtonDB for community compatibility reports on games not yet Deck Verified.
- Desktop Mode allows installation of alternative game launchers and tools.
- Windows can be installed on the Steam Deck for games that are completely incompatible with Linux, though this removes SteamOS features.
- Cloud gaming services like Xbox Cloud Gaming or GeForce Now can be accessed through the browser in Desktop Mode.
Conclusion
Steam is fully compatible with the Steam Deck as the device was built for this purpose. The combination of SteamOS and Proton enables the majority of the Steam library to run on the handheld. Compatibility varies by game, and the Deck Verified program provides a useful reference for checking individual title support.
