The Oasis driver arrives just under one year after Microsoft started rolling out Windows 11 24H2, which completely removed support for Windows MR. This meant Acer, Asus, Dell, HP, Lenovo, and Samsung PC VR headset owners could no longer use their headset at all, not even on Steam, since Windows MR had its own runtime and only supported SteamVR through a shim.

Matthieu Bucchianeri’s Oasis solves this problem, for free. Oasis is a native SteamVR driver for Windows MR headsets, adding direct SteamVR support. No other software is required, except for SteamVR itself.
