The HP Reverb G2 VR headset required Microsoft Windows Mixed Reality support.

As Microsoft’s WMR never had much market share, Microsoft announced that WMR would not be supported in Windows after 23H2 – and will not be supported, apparently, even in 23H2 after November 2026.

WMR was required for VR headsets sold by HP, Samsung, Acer, Lenovo and others; presumably they are dead too.

I did not get my money’s worth out of it. While I had it for some time, it had been used little for various reasons, including some health and eye/vision issues (since resolved).

I used it recently with MS Flight Simulator and it worked well. But once this computer gets updated from the now dated Windows 11 23H2, the HP Reverb G2 will no longer work.

If the PC is updated from the now dated 23H2 to either 24 or 25 versions of Windows 11, the G2 becomes an expensive paperweight. The WMR components including software that was embedded into the Windows OS – and “old” WMR components cannot be added to a newer version of Windows.

There is a “community driver” (OASIS) that may enable the G2 to work on Steam VR (which is what most people use). Unfortunately, I do not have the Steam VR version of Flight Sim – but the MS Store version.

An August 2025 news story about this: HP Reverb G2 & Co: New driver makes Windows VR glasses usable again | heise online. This says the OASIS driver is intended primarily for use with Steam VR (not other applications built for WMR). Also, it appears it does not work with AMD graphics cards, only Nvidia – the system I want to use it on has a high-end AMD GPU.

The OASIS driver was released around September 2025.

For now, I am staying on 23H2 on an older PC (with a 2019 GPU not designed for VR) – to still use the G2. But the real solution will be to buy a new VR headset.
