Today, games that have been tested for Steam Deck compatibility by Valve are now available on SteamDB, with a total of 67 titles.
At present, games such as Death Stranding, Isaac's Combination: Rebirth, Dark Souls 2: Original Sin Scholar, Dark Souls 3, Hollow Knight, Fallout, Deathgate, Gunfire Reborn, Dyson Quest, Portal 2 and other games have passed the test and are basically games that can run smoothly on steam Deck.
Games such as The Witcher 3: Wild Hunt, War Thunder, Tomb Raider: Rise, Plants vs. Zombies Annual Edition, and Dyson Quest May require some manual adjustments before users can play.
After verification, "Persona 4 Gold Edition" found that it could not be run, and could only wait for the official solution.
