The stats component displays a UI with performance-related metrics. The stats component applies only to the <a-scene> element.

Example

<a-scene stats></a-scene>

Metrics

fps: frames per second, framerate. Aim for stable 90 fps with the WebVR 1.0 API.
requestAnimationFrame (raf): Latency.
Textures: number of three.js textures in the scene. A lower count means the scene is using less memory and sending less data to the GPU.
Programs: number of GLSL shaders in the scene.
Geometries: number of three.js geometries in the scene. A lower count means the scene is using less memory.
Vertices: number of vertices in the scene.
Faces: number of faces in the scene.
Calls: number of draw calls on each frame.
Load Time: how long it took for the scene to start rendering, in ms.
Entities: number of A-Frame entities.

Click or tap on the headings to collapse groups of metrics. If you tap "Framerate", then fps and raf will collapse.
