    The Tobii Eye Tracker 5L (which is the same hardware as the Eye Tracker 5) is able to increase the gaze sampling rate from 33Hz to 120Hz by switching to a *fast run mode*

    Please provide the process to enable Fast Run mode on the Eye Tracker 5.
    fast run mode would disable head pose, which should be a choice per customer.

    Hi @goodentree, you can query and set the run mode via the Tobii Stream Engine API
    using the following functions

    tobii_enumerate_output_frequencies
    tobii_set_output_frequency

    Which are explained in more depth with samples @ https://tobiitech.github.io/stream-engine-docs/

    I should have been more specific, what is the range of the output frequency for a device without the special license (default)?

    Hi TJ, I am not sure what you mean by range as the device only operates between two established frequencies (33 & 120). Although these values will deviate slightly during recording, they are intended to operate on average at these values.
