just use opentrack with a non-shit 60fps+ wired webcam. latency is going to fuck up any and every app-based solution.
if you're on thirdie hardware it will be hard on your cpu but probably still better than whatever you're using now.
if you can't find a good webcam, there are plenty of tutorials to diy irtrack with a few leds, a coat hanger, a floppy disk, and a usb cable.
