NVIDIA CloudXR Runtime Overview

The NVIDIA CloudXR Runtime is a GPU-accelerated Extended Reality (XR) streaming platform that streams high-quality XR experiences from powerful servers to lightweight clients over standard networks. Its core architecture decouples rendering from display, allowing intensive XR applications to run on high-performance servers.

The CloudXR Runtime is the essential server-side component, provided as libraries for building OpenXR server applications on Windows and Linux systems.

CloudXR Runtime Key Features

The Runtime acts as an OpenXR-compliant runtime, enabling applications to use the standard OpenXR API while it automatically handles the streaming functionality.

• Streaming: Provides GPU-accelerated video encoding for high-quality visuals. Audio is also captured and streamed alongside video (currently Windows only).
• Input Integration: Receives and processes client input—including head tracking, controllers, and hand tracking—via the standard OpenXR action system.
• Advanced Features:
  • Foveated Rendering: Reduces quality in peripheral vision areas to help optimize bandwidth.
  • Opaque Data Channel: A custom bidirectional communication channel for application-specific data using the XR_NV_opaque_data_channel extension.

Runtime Management API

The CloudXR Runtime Management API is provided for controlling server-side functionality. This API is used to manage and configure the streaming environment and includes features such as:

• Initialization and Setup.
• Stream Manager configuration.
• Integration of the XR Opaque Data Channel.

Note: CloudXR is an end-to-end system; the CloudXR Runtime must be paired with a compatible CloudXR client (built with CloudXR Framework or CloudXR.js) to establish a working streaming session.
