NVIDIA CloudXR.js Sample Client

Debug Settings

Device Profile Load defaults

Load recommended defaults for a target device. You can still override settings below.

Proxy Configuration Proxy URL

Media Server Configuration (Optional) Media Address Media Port

Configure WebRTC media server address and port for NAT traversal. Only needed when the streaming server is behind NAT. Leave empty to use server-provided ICE information.

Frame Rate Configuration Device Frame Rate

Select the target device frame rate for the XR session

Maximum Streaming Bitrate Megabits per second

Select the maximum streaming bitrate (in Megabits per second) for the XR session

Codec Selection Video Codec

Select the preferred streaming codec. Availability depends on browser and server support.

Stream Resolution Configuration Per-Eye Width (default: 2048)

Per-Eye Height (default: 1792)

Configure the per-eye resolution. Width must be a multiple of 16 (min 128); height must be a multiple of 64 (min 128).

Depth Reprojection Grid Columns (optional)

Depth Reprojection Grid Rows (optional)

Grid rules: leave either field blank to use factor mode, or set both to integers >= 2 for explicit mesh resolution.

Preferred Reference Space

Select the preferred reference space for XR tracking. "Auto" uses the original fallback logic (local-floor → local → viewer). Other options will attempt to use the specified space only.

XR Reference Space Offset X Offset (centimeters): Horizontal Y Offset (centimeters): Vertical Z Offset (centimeters): Depth (facing outward)

Configure the XR reference space offset in centimeters. These values will be applied to the reference space transform to adjust the origin position of the XR experience.

XR WebGL Layer Options Layer Alpha Layer Depth

Controls the XRWebGLLayer framebuffer attachments for alpha and depth.

Pose Smoothing

Enable or disable secondary smoothing on predicted positions to reduce jitter. This only affects position, not orientation.

Pose Prediction Factor: 1.0

Scale the pose prediction horizon (0.0 = no prediction, 1.0 = full prediction). This multiplier affects both position and orientation prediction strength.

Quest Texture Optimization

Enable texSubImage2D for texture updates. Improves performance on Meta Quest devices but may cause issues on headsets with older Chromium forks.

Quest Color Workaround

Enable Display P3 color space for texture unpacking to work around color rendering issues on Meta Quest devices. Only enable this if you're experiencing color issues on Quest.
