Video passthrough, refined

Headlining this release is an extensive upgrade to the passthrough experience provided by the XR-4 Series.

The overall image quality has been massively improved with finer tuned sharpness, improved color balance, reduced noise, full exposure controls, and automatic white balance.

Major improvements also lie in the chroma key masking performance and with significant reductions in latency in both eye-tracked foveation and the autofocus feature of the XR-4 Focal Edition.

Please note that we will continue to make further improvements on passthrough image quality and latency through our future software updates.

Sharper tracking

4.2 further optimizes inside-out tracking for the XR-4 Series, focusing on providing a more accurate experience with reduced jitter especially in common office or studio-style environments.

Occurrences of heavy CPU loads whilst using inside-out tracking have been addressed, especially with the use of Varjo Controllers.

With the accompanying tweak tool, 4.2 users will be able to manually test which inside-out cameras are used to better suit different environments (top, bottom, or experimental use of both top and bottom).

Further improvements to the tracking experience, as well as a marked improvement to the mixed reality alignment, are expected in forthcoming updates.

Enriched experience

The speed of the integrated eye tracking on all XR-4 Series headsets has been improved for a better foveation experience with virtual content, even over long duration sessions.

The first time use and room setup process has been enhanced and streamlined, featuring intuitive troubleshooting, automatic floor detection, room recognition, and the ability to reset the setup without resetting the headset.
