I use the EyeX on an older Macbook Pro using VMware Fusion. I created a virtual serial port in OS X and then attached it to a Windows 10 guest. I then wrote a few lines of code using the SDK that print out the eye coordinates to the virtual serial port. An automation script takes care of running the program each time guest starts up, and cleaning up afterwards. It was a pain to get worked out at first, but so far it’s been working great. There isn’t any noticeable delay, and I don’t have any performance issues. I use Python to monitor the serial connection and act accordingly, though any language with a serial library should work. If this sounds like something that might work for you, let me know and I’ll try to provide you with some more information. The source code isn’t on Github yet, as it’s sort of a mess and just something I used for a side project a while back.
