Valve’s Steam Deck is focused on the idea of your personal PC library coming with you, but there is one small issue: Some games on Steam won’t be playable.
According to ProtonDB via PC Gamer, half of Steam’s top games won’t be playable on Steam Deck. Destiny 2, Apex Legends, PUBG, and Rainbow Six Siege won’t be compatible with the preinstalled SteamOS because of the anti-cheat software not activating on the Linux-based operating software. This leaves the player locked out of the multiplayer servers.
Valve did say that it is currently “improving Proton’s game compatibility and support for anti-cheat solutions by working directly with the vendors.” Obviously, a more drastic change would involve removing SteamOS from the device, and install Windows. Steam Deck is entirely capable of doing so, and Valve has made it clear that it’s up to the user.
If this list of incompatible games doesn’t affect you–and you’re still looking to get your hands on a Steam Deck–the preorders are open right now on Steam’s website.
