How to Install DirectX on Steam Deck
Super simple! Steam Deck runs on SteamOS, which is Linux-based, but it's got Proton - a compatibility layer that lets most Windows games, including those needing DirectX, run smoothly. So, when you install a game through Steam that needs DirectX, Proton takes care of it automatically. You really don't have to do anything extra. Just install your game and play!

DirectX on Steam Deck? No worries! It's all handled by Proton. So just install your game from Steam and enjoy. No manual installs needed.
I've been using my Steam Deck for months and never had to manually install DirectX for any game. Proton, which comes with SteamOS, automates the process. Just download your game, and you're set!
