Here's yet another Steam release from Ubisoft, as they continue dumping their older titles on Steam. Watch Dogs: Legion is here and playable on Steam Deck. We've already had Ghost Recon Breakpoint, The Division 2, Immortals Fenyx Rising and Assassin's Creed Valhalla along with Trackmania on the way soon too. Clearly, Ubisoft want the Steam monies.
The good news with Watch Dogs: Legion is that it doesn't put up much of a fuss on Steam Deck. Much like previous Ubisoft release there's no real Steam integration so no Steam Achievements, and once again it has Denuvo Anti-Tamper so if you keep changing Proton versions for testing and / or keep swapping between machines, it might eventually lock you out for 24 hours if you've done it too much (very annoying).
Apart from that, it's pretty smooth sailing in terms of how stable it is but performance like a lot of open-world games needs you locking it to 30FPS because it cannot keep a stable 40. I tested between DirectX 11 and DirectX 12, with DirectX 12 clearly being a lot smoother overall.
