Valve today put out frequently asked questions (FAQs) that shed light on many aspects of Steam Deck, the elusive new portable game console. Steam Deck is one of the first mass-market handheld consoles based on the PC architecture (if you don't count the various smartphones based on Intel Atom chips), or x86-based tablets. It turns out that Valve engaged in some segmentation between the storage-based variants. All three capacity variants feature optically-bonded glass IPS LCD touchscreens with 10-point multi-touch, but the 512 GB variant has an additional anti-glare treatment.

Steam Deck combines Linux-based custom operating system, along with the Steam UI and DRM platform, although it is possible to play non-Steam games through the Proton translation layer software. You can add games to your library just like on Steam on desktop. The Steam software itself has a custom UI optimized for the console, which replaces the Big Picture mode of conventional Steam desktop. Just like on regular Steam, the Steam Deck console lets you launch and play a game without an Internet connection, unless the game requires it.
