184.108.40.206 has made the MCDU lag worse. Change log shows there was work done in this area "Implemented new FMS/MCDU threading model to mitigate laggy display/systems issue" Previous build did not exhibit this problem. I did not bother to take off or complete the MCDU programing due to the bad lag. Link to video can be found in beta forum which you have seen. Running P3Dv4, Windows 10.
