Tackling the Diablo 4 compatibility issue on Steam Deck initially requires identifying key challenges. Firstly, Windows 10 is not native to the Steam Deck, which operates on a modified version of Linux (SteamOS). Additionally, Diablo 4 demands certain Windows-exclusive features like DirectX 12 and Battlenet, which pose compatibility hurdles within the SteamOS environment.

Solving Real Diablo 4 Steam Deck Needs Windows 10 Challenges

To address these challenges, one solution involves employing Proton, a compatibility layer that seamlessly integrates Windows games into Linux systems. By utilizing Proton, users can seamlessly install and launch Diablo 4 on their Steam Decks, mitigating compatibility issues. Additionally, installing Windows 10 directly onto the Steam Deck is an alternative approach, although it requires advanced technical proficiency and may compromise the stability of the device.
