Enhanced Freedom for Window Placement
Unlike Apple’s visionOS and Meta’s Horizon OS, which allow for flexible positioning of 2D windows, earlier versions of Pico OS restricted window movement to a 360° spherical boundary. All windows were limited to an identical distance, an aspect we noted in our hands-on experience.

With the rollout of Pico OS 5.13.0, users can now position windows anywhere they choose, including adjusting their distance from the user.
Convert 2D Photos to 3D
The latest update enables the Pico 4 Ultra to transform any image from your gallery into a 3D visual, with batch conversion supported, making it easy to process numerous images simultaneously.
This feature was previously introduced with Apple’s Vision Pro and its visionOS 2 release in September.

Pico OS 5.13.0 also allows you to view Spatial Photos captured with the iPhone 16, a feature currently exclusive to Apple Vision Pro users.
3D Recording Capability
This update enables 3D screen recording on the Pico 4 Ultra. While the headset could already record 3D video through passthrough cameras, this enhancement allows for the inclusion of virtual and mixed reality elements as well.
This innovative functionality sets the Pico apart from other headsets on the market.
Adjust Graphics & Performance Settings
Pico OS 5.13.0 introduces new options that permit users to override default graphics and performance settings using an app called Performance Tuner.
This includes customizations for screen refresh rates, rendering resolutions, CPU and GPU levels, and fixed foveated rendering settings. Note that Performance Tuner is intended for developers and requires enabling developer mode.
Enhanced Passthrough & Hand Tracking
ByteDance claims that Pico OS 5.13.0 improves the quality of passthrough visuals in low-light situations and also enhances hand tracking, detailing several improvements:
- Reduced latency and occurrences of false touches.
- Improved tracking stability in dim environments.
- Enhanced gesture recognition accuracy and fidelity.
- Better alignment between virtual hand models and real hands in Seethrough mode.
- Resolved an issue where hand rotation interrupted dragging.
Upgraded Body Tracking
The update also enhances body tracking capabilities on the Pico 4 Ultra, which utilizes the Pico Trackers accessory typically worn around the ankles.
- Pico Motion Trackers Add Leg Tracking To Pico Headsets
- Pico Motion Trackers add leg tracking to Pico 4 Ultra, Pico 4, and Pico Neo 3 and feature a clever rapid calibration technique.

ByteDance highlighted the following enhancements to body tracking:
- Greater stability for posture during extended periods of sitting or lying, minimizing character drift and standing inaccuracies.
- Increased update frequency for full-body motion tracking data, leading to smoother movements.
- Improved flexibility and precision for complicated lying positions, enhancing the experience when paired with the waist tracker.
