How did they figure this out? Steam Deck is not yet available, but it uses Proton, a compatibility layer that allows you to launch native Windows video games on Linux-based operating systems, used by SteamOS. So it's not hard to figure out which games will run on new hardware and which won't. For example Proton is not compatible with many anti-cheat systems and makes it impossible to start very famous titles such as PUBG, Destiny 2, Apex Legends and Halo Infinite multiplayer.
To know if the Steam Deck launch will go smoothly and users will be satisfied, we just have to wait until next year, when it will be available. Valve had to postpone the launch due to the difficulty of finding some electronic components, due to the microconductor crisis, but it now seems to have solved, or at least buffered the problem. So we look forward to seeing the first Steam Decks shipped in February 2022.
