HTC has released a beta for its Vive Ultimate Tracker that brings support to third-party PC VR headsets, such as PC-tethered Quest and Pico headsets, letting you do body tracking in supported apps.

Unlike previous Vive Trackers, which required SteamVR base stations, Vive Ultimate Tracker makes use of inside-out optical tracking thanks to each unit’s dual wide-FOV cameras.

At launch in November, the device was only compatible with HTC standalones Vive XR Elite and Vive Focus 3. As promised, now the company is launching beta access to OpenXR/SteamVR based PC VR headsets, like Valve Index or Quest 2/3/Pro with Link.
