Hi there, yes I have had it working until today when I changed to Win 10 (but thats another problem for another thread).
When you have the Tobiieyex set up and working on your desktop you just open infinite screen and make sure its on the ED tab (just to be sure).
Vjoy should be working in the background you shouldnt have to do anything with it.
In ED go to options and to your headlook settings.
Click on headlook X acces and gaze in the X direction.
Repeat for Y.
It should be working now in game (you might need to change the invert here and there afterwards).
I played it many times with it to my full enjoyment you can see clips on it on youtube and Twitch just look for Pleijpje.
Kind regards,
