New in 0.3.5: Half-Life: Alyx and OpenComposite

One-click OpenComposite. The Patch button now downloads OpenComposite automatically
(one time) and installs it as the translation layer for classic OpenVR titles. It speaks
every historical OpenVR interface version, so 2017-era games that crashed on the built-in
shim now run. The shim remains the fallback if the download is unavailable.
Half-Life: Alyx patching that survives Steam. SteamVR-native Source 2 games import an
undocumented export (VRControlPanel) that OpenComposite does not provide, which aborted
the game at load. Patching now installs a small proxy dll that supplies the export and
forwards everything else to OpenComposite. If a Steam update or reinstall wipes the game
folder, hitting Patch again restores a working setup in seconds.
Upside-down menus fixed. OpenComposite games get invertUsingShaders enabled per game,
so flipped eye buffers and overlay quads (menus, loading screens) render upright.
Per-game display orientation. New Auto / Force flip / Never flip control for games
that render inverted, with matching fov handling in the runtime.
Tracking robustness. Both fov axes are sanitized per eye, preventing warped
projection when a game hands back degenerate view data.
First-run fix on Whisky-less Macs. The app no longer defaults its Wine path to a
nonexistent Whisky binary; it now prefers whichever Wine build actually exists.
