Bug ID: 56145
           Summary: Wine lacks VR support ( OpenVR/OpenXR runtime shim)
           Product: Wine
           Version: 9.0-rc3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

Currently VR support in Linux gets to the point where it becomes viable option.
Linux native apps tend to do just fine , but there's no way for VR capable
windows apps running trough Wine to detect/use VR devices.
VR is supposed to be supported on Proton and hacky Wine-Proton hybrids, where
first option limits support to apps from Steam and second one is a bit
cumbersome to get it working.
To solve this issue wine environment could provide thin VR runtime environment
that catches calls from apps and direct those to linux native VR runtime that
is installed on user system. Wine OpenXR library shouldn't be that complex as
it'd be simple 1:1 mapping of OpenXR API. For Valve OpenVR API there are two
possible approaches, one similar to OpenXR where wine just forward calls to
SteamVR or it could translate calls to OpenXR, like OpenComposite does, then
call OpenXR runtime on Linux side.

I believe that proton actually has (open source) code for this sort of shim:

https://github.com/ValveSoftware/Proton/tree/proton_9.0/wineopenxr

But I'm not sure how valuable that is because each VR game seems to install
their own VR runtimes (or use Steam's).

Proton OpenXR loader is just half useful, first because it works only with
Proton, has hard dependence on Steam and SteamVR, so it won't work for apps
that aren't run in Steam runtime environment (container). Some more details in
