The SteamVR Beta has been updated with the following changes.

If you encounter issues with this update, please post in the SteamVR Bug Report forum. If possible, please include a system report to aid in tracking down your issue.

SteamVR:

• Added Debug Commands interface (under Developer menu).
• Fixed a crash when running through Windows Remote Desktop.
• Moved the “Searching…” popup into the main status window.
• Added a “Standby” status for when the HMD isn’t being worn.
• Fixed Steam crashing when SteamVR was launched and 'Enable GPU Profiling' was enabled.
• Deprecate driver-supplied Prop_DoNotApplyPrediction_Bool. (See Windows MR notes for more information).
• Add a per-driver “loadPriority” (higher is earlier loading) to control the order that we check drivers for available HMDs. The default loadPriority is 0. Drivers can set a different default in resources/settings/default.vrsettings. The user can override those settings in their personal steam/config/steamvr.vrsettings file. Drivers with the same priority continue to be loaded in alphabetical order as before.
• The default null driver loadPriority (which has historically been forced to be “last”) is -999.
• The default iVRy driver loadPriority is -100 because it takes a fixed 5 seconds to initialize even when not in use. Users of iVRy should not notice any change.
• The default AMD WVR driver (part of AMD “Relive”) loadPriority is -900 because it will always claim to have an HMD (previously because it started with “a” it would block access to all other actual HMDs whenever it was installed).

Valve Index:

• Always treat thumbsticks as touched when they are moved away from the center.

Oculus:

• Updated Oculus SDK to 1.37.0.
• Fixed warning not popping up when the user has an outdated version of the Oculus software.
• Switched all Rift haptics to use the non-buffered API.
• When Rift S is used, don't show tracking camera icons.
• When Oculus Guardian is updated while SteamVR is running, update Chaperone automatically without requiring a restart.

Windows MR:

• When using third-party software to mix Windows MR HMDs with non-MR trackers and controllers, correctly predict poses for the non-MR devices.
  (Currently the MR driver supplies already predicted poses, and uses an HMD velocity of zero to prevent HMD pose extrapolation.)

Compositor:

• Fixed a Motion Smoothing related crash on AMD hardware.
• Fixed startup crash when trying to use wireless on unsupported hardware.
• Added support for DXGI_FORMAT_R32G8X24_TYPELESS textures passed as depth from applications.
• Added support for passing left-handed projection matrices when supplying additional depth info.
