Description
Feature Request
I confirm:
- that I haven't found another request for this feature.
- that I have checked whether there are updates for my system available that
contain this feature already.
Description
Unfortunately there are still a few 32-bit VR games in existence like Half-life (2) VR mod.
Using OpenComposite (https://gitlab.com/znixian/OpenOVR) these could be run with OpenXR instead
by replacing the game's openvr_api.dll with the OpenComposite dll. But this is currently not
possible without 32-bit OpenXR loader support.
Btw this is not related to support for Monado. This can be even used with SteamVR as OpenXR runtime
to bypass bugged behaviour in Proton's or SteamVR's OpenVR implementation.
Since OpenComposite is open source unlike SteamVR this can also be used to bring features to OpenVR
that aren't otherwise possible.

Research direction
The issue names no files, tests, or entry points, so first trace how Proton handles OpenXR and 32-bit loader support. Compare the existing loader paths and runtime assumptions, including OpenComposite and SteamVR rather than Monado. Done means 32-bit VR games can use OpenXR through the described setup.
