I use Facetracknoir with Rof, wop, Cod, fsx with a
Logitech 5000. It works good and smooth, finally I'm free to look anywhere without using my thumb on the joystick at zero cost. It is not difficult to set it, follow the instructions on the facetracknoir site, and known issues if you have a i5 or i7 cpu. It seems that a ps3 eye cam gives better results, but I'm happy enough with my quickcam 5000.
