A Microsoft engineer, Matthieu Bucchianeri, has developed the Oasis driver, which allows Windows Mixed Reality headsets to support SteamVR after the platform's discontinuation. The driver is available for free on Steam and requires an Nvidia GPU. It operates independently of the Mixed Reality Portal, enabling users to run OpenVR and OpenXR applications through SteamVR with comprehensive tracking for headsets and motion controllers. Bucchianeri reverse-engineered Nvidia and SteamVR code to create the driver, which is not open source but is free for users to download. Quick start documentation is provided for setup assistance.

Microsoft discontinued support for the Windows Mixed Reality platform with the rollout of Windows 11 version 24H2, rendering many headsets unusable. A new driver, available for free download through Steam, allows users to revive their Windows Mixed Reality headsets, compatible with any Windows Mixed Reality device. The driver works on Windows 11 versions 24H2 and 25H2, but is only compatible with PCs equipped with NVIDIA graphics cards due to limitations in AMD and Intel drivers. Users can connect their headsets, download SteamVR, and access a wide library of games and applications. Microsoft announced the deprecation of the Windows Mixed Reality platform in 2023, coinciding with the end of HoloLens production.

The SteamVR Beta has introduced an automatic installation of the third-party 'Oasis' driver for Windows Mixed Reality (WMR) headsets, responding to Microsoft's discontinuation of support for these devices in Windows 11. This update allows WMR users to regain compatibility with SteamVR without the Mixed Reality Portal application, although the Oasis driver currently only supports NVIDIA GPUs. Valve has integrated this driver into SteamVR Beta (v2.13.1) to assist WMR users on unsupported Windows 11 versions. Additionally, Valve aims to enhance user experience by ensuring compatibility across various VR devices, including making Half-Life: Alyx compatible with all SteamVR-supported headsets.
