Valve has launched another small update for the Steam Deck with SteamOS 3.6.6 Preview now available for testing which may be essential if you're playing ELDEN RING.
  • Fixed a an issue with a rare session crash during early startup of ELDEN RING
  • Fixed a general issue affecting all units on 3.6, and OLED units on 3.5, causing a slow memory leak during gameplay
  • Fixed a DSP firmware crash with previous 3.6 versions that could result in internal sound disappearing until next reboot
  • Improved responsiveness of session restart in case of session crashes caused by certain GPU errors
  • Fixed an issue that could cause videos to stutter in titles such as BlazBlue Centralfiction

Some pretty good fixes. Unfortunately you’ll need to be on the beta/preview channel to get them, but hopefully it won’t be long before they come to stable.
