A new Proton GE update was released yesterday with some pretty big changes. All of the Proton components have been updated to their latest, while there have been some big protonfixes for Zenless Zone Zero, Duet Night Abyss, Planet Crafter, and FSR 4. There are also some big new patches for VR working outside of Steam and a new umu.exe that should help with some third-party launchers.
For those who don’t know about Proton GE, how to get it on the Steam Deck, or how to update, check out our Proton GE guide! We go over all of this and explain why having GE is important.

Patches:
NEW: Added new wineopenvr patches to allow VR to work outside of steam for non-steam games (examples such as GOG version of ProjectWingman, Overload, Star Citizen). Compatibility tested using Meta Quest 3 with WiVRn. To use, setup WiVRn, then launch games with the additional environment variables WiVRn instructs. Tested flatpak system and user modes as well as standalone package install.
NEW: Rebased em10/wine-wayland patches, should have some new dead-key fixes.
Patch added to fix Star Citizen EAC warning popup
More winepulse patches from Vyrolian
NEW: Added new umu.exe that works the same way steam.exe does — this is used now instead of the standard wine start.exe, it should help some 3rd party launchers work better by making them run the same way steam runs them.
