Hi @rasa, sorry for the delay as I was trying to determine if the debug.log is necessarily a reliable means of determining the sample rate. I think to be certain, the easiest thing would be if you run the Core SDK samples for Visual Studio on your system.
You can download some common sample for free @ https://github.com/Tobii/CoreSDK/tree/master/samples
and running the ‘streams’ samples, you will be able to easily determine the rate of gaze capture in one second (or preferably over a minute and divide by 60).
Please try it out and let us know how you get on…
