VisionOS 26.4 drops spatial upgrades
visionOS 26.4 adds NVIDIA CloudXR for low‑latency PC/Mac VR streaming, an 'acoustic memory' room feature, 2x faster spatial audio initialization, new foveated APIs and WidgetKit — plus a new spatial social app for face‑to‑face persona chats. These are big for creators mixing live audio, spatial environments and remote collaboration. (x.com) (x.com)
Apple pushed visionOS 26.4 to Vision Pro on March 24, 2026, marking the fourth update to the visionOS 26 cycle and rolling out to headsets via the Settings app. (macrumors.com) The update adds native NVIDIA CloudXR 6.0 support, which enables dynamic foveated streaming on Vision Pro at up to 4K resolution and 120 Hz refresh for untethered RTX-rendered experiences. (9to5mac.com) NVIDIA’s CloudXR 6.0 lets the headset share user gaze data with the renderer to drive server-side foveation over a private, secure connection and includes multi‑platform Xcode templates so developers can target iPhone, iPad and Vision Pro from the same codebase. (9to5mac.com) Publishers and developers are already naming workloads that benefit: NVIDIA and partners highlighted titles and pro tools such as iRacing, X‑Plane and Autodesk VRED, positioning Vision Pro as a front end for RTX workstations and cloud-based digital‑twin workflows. (the-gadgeteer.com) Apple’s official release notes describe Spatial Audio as now “starting faster in familiar spaces” by storing the acoustic properties of rooms previously visited. (support.apple.com) Coverage of the feature notes there is no user-facing calibration or toggle for the new “acoustic memory,” meaning the system reuses learned room acoustics automatically. (lavoixdefrance.fr) NVIDIA promoted the visionOS integration at its GTC event and positions CloudXR 6.0 as an OpenXR‑compliant, GPU‑accelerated streaming platform that offloads rendering from the headset to RTX GPUs in workstations or the cloud.
