Yep i did noticed that. Pretty awesome hack. Im pretty sure that virtual/fake screen method would impact to fps. But hope you have time to check that also. My next project is working track IR with webcam or android phone, without big extra cost. This forward view solution (Forward View, No Instrument Solution (Plus "Walkaround" for every plane ! )), with your ipad solution with working free TrackIR… that is the case for me to discover world in this amazing simulator.
