A Microsoft employee is developing a native SteamVR driver called "Oasis" to revive Windows Mixed Reality (MR) headsets, which lost functionality after the Windows 11 24H2 update eliminated support for these devices. The previous runtime that allowed Windows MR headsets to interface with SteamVR is now obsolete. Matthieu Bucchianeri, a software developer with experience at Sony and SpaceX, is leading this project, which involves deep reverse-engineering. The Oasis driver is currently compatible with Nvidia GPUs, and Bucchianeri is in talks with AMD for potential compatibility. He plans to release the driver for free in the fall.
