Performance notes

Eye raycasts​

  • Combined gaze ray is always computed for gameplay when both eyes are confident.
  • Per-eye raycasts are optional and controlled by RecordingOptions.includeSeparateEyesGaze.

Raycast counts:

  • Separate eyes OFF: 1 raycast (combined)
  • Separate eyes ON: up to 3 raycasts (left, right, combined)

In heavy scenes (many colliders), turning off per-eye raycasts can reduce CPU cost.

Logging frequency​

Continuous logging runs at FixedUpdate rate. Higher rates increase file size and CPU usage.

Strings in CSV​

Some enum/flag fields are written as strings for readability. This increases file size but simplifies inspection and debugging. A later pipeline can compress/encode as needed.
