CPU usage is rather high for gaming

[Xaklse]

I have an Intel Core i7-7700HQ and I verified that the CPU usage is rather high, with all cores (+HT) being used.
Maybe there is a way to limit the number of threads, or switch to a less intensive algorithm in OpenFace.
Did you test GazeTracker with other FaceModelParameters?

I didn't test different parameters but I guess that there might be one. Otherwise, you might have to modify the call to the C++ code or check if there's some missing parameter that could be useful in the C# wrapper.

My initial idea was to run this program in a raspberry pi or some small computer so it doesn't affect the main CPU...

OpenFace offers two other less accurate algorithms through the boolean params in FaceModelParameters; unfortunately I can't test them unless I download and rebuild GazeTracker code.
Do you think it would work with VS2017?

[Xaklse]

It works for VS2017.
I get less CPU usage with the other algorithms... any idea on how to tell the ImageProcessDataflow object to use different landmarkExtractor and dataExtractor on-the-fly, with a configurable algorithm selector?

I'm right now moving to another city but as soon as I'm stablished I'll try to have a look, is this parameter dependent on the building or can it be added it in the C# wrapper and send it to the unmanaged code?

Just check the constructor of ImageProcessDataflow, where the FaceModelParameters are created.
