Hi Alex (@limdne),
1) the 60Hz is an average value which naturally varies owing to various factors such as CPU load, detectability
of eyes, other running applications etc. Therefore the mentioned frequency is more of guideline under optimal circumstances.
If you require eye tracking with precise frequency ranges then you should check out the Tobii Pro range of eye trackers.
2) This forum is intended for support regarding EyeX Eye trackers only and indeed the Tobii 2150 and Clearview are deprecated products which require a specialist to deal with. Please contact Tobii Pro support for further assistance regarding this issue @ http://www.tobiipro.com/contact/contact-support/
