Notable features include non-Steam game compatibility for Proton, ext4 and exFAT file system support for the SD cards, user-accessible BIOS with multi-boot option along with SD card OS boot, plus PC game controller mode through Remote Play. The updated FAQ also confirms that external GPUs are not supported and the console is not specifically optimized for VR games.

The first limited batch of Steam Deck handheld consoles is expected to ship this holiday season. Valve did a great job advertising the buzz word hardware specs to hype up the gaming community, but some quality of life details were not really detailed too well. To answer some of the burning questions from the community and press, Valve recently updated the FAQ page with new information revealing more interesting and subtle features for the upcoming console.

Here is a list with the more relevant features included with the updated Steam Deck FAQ:

  • The Proton compatibility layer allows users to run non-Steam games.
  • The “Add a Game” feature from the desktop client is available with the Steam Deck client.
  • Steam Deck formats the SD cards with the ext4 file system supporting casefolding, also reads exFAT cards
  • Users can utilize the Steam Deck as a PC game controller through Remote Play.
  • VR headsets can technically be paired with the Steam Deck, but the console is not optimized to run VR games.
  • Steam Deck runs at full performance by default in portable mode, so keeping it in charge mode does not unlock any performance benefits.
  • The audio jack combines line-out and mic
  • The touch screen supports up to 10 independent touch sources
  • Users will be able to access the BIOS, which supports multi-boot
  • Separate operating systems can also be booted directly from the SD card
  • There is no support for external GPUs (obviously, since there is no Thunderbolt interface)
  • As the Steam Deck becomes available in more regions, Steam may consider partnering up with retailer stores for additional sale points.
