I used facetracknoir for a little while, but the faceApi pluggin is a heavy load for the CPU with means you loose fps.
It is true when the users say you can't take a cup of coffee or something else, all these things together makes it horrible to me and I quit with it.
But with a 3 point ir led cap it works ferry smooth, you can use the pointracker pluggin and no filter (EWMA2, Accela) at all, the only thing you have to do is calibrate in the pointtracker menu.

Thirst of all the threshold slider after that you go to de tab where you can find your 3 point cap menu, gives in the distance between the leds and calibrate.
When you ready with those things you can push the start button and start-up ETS2, now you can play with the curves for a smooth movement, and it isn't less hard to do like the faceapi (facetracking).
With this all together you will expire how smooth it works and the point tracker plugin takes a less from your CPU as the faceapi plugin, this means you don't loose fps.
For the 3 points ir cap I buy 3 ir leds, 3 resistor 30 Ohm 1/4 watt and a 500mA DC adapter, for the manual >
