The end-to-end sample delay is the total time it takes for an eye position to be captured by the camera, processed by the Host PC, and transmitted back to your Display PC. This delay is critical for timing-sensitive tasks, such as gaze-contingent paradigms.
The total delay depends on your sampling rate and the Link/Analog filter setting.
