77 YesCrimson Desert can run on Steam Deck through ProtonValve's compatibility layer. The game did not initially work on Steam Deck during the pre-release review period.

1111 Performance Expectations

1313 Frame rate: The game struggles to maintain a stable 30 FPS even on the lowest graphical settings. Frame drops to around 17 FPS have been reported in larger cities and during intense combat with many enemies on screen.Boss fights: Visual effects during boss encounters cause severe frame rate degradation, making some fights very difficult to play through reliably.Open-world traversal Using faster movement methods (such as horse riding) causes additional performance drops compared to walking on foot.Temperature and battery: The device typically runs at 77 to 83 degrees Celsius with a TDP setting of 20 to 24 watts, giving roughly 2.5 hours of battery life.

2323 Denuvo DRM Considerations
2424  
2525 Crimson Desert uses Denuvo anti-tamper DRMwhich has specific implications for Steam Deck and Linux users:
2626  
2727 Denuvo allows a maximum of 5 device activations per 24-hour period. Each time you change or update your Proton version, Denuvo treats it as a new device activation.If you exceed 5 activations in a single day (for example, by switching between Proton versions while troubleshooting), you will be locked out of the game for 24 hours.The safest approach is to stick with a single Proton version (the default Proton Hotfix branch) and avoid switching between experimental versions.

2929 Best Use Case
3030  
3131 Given the current performance limitations, Crimson Desert on Steam Deck works best as a companion experience alongside a primary PC or console playthrough. Exploration, puzzle solving, and story progression in calmer areas are generally playable. However, demanding combat encounters and boss fights are likely to be frustrating due to frame rate instability and input lag.
