In Prepar3D V5, with the new v5-compatible version (1.0.2.0), I am getting the same problem as with the previous version: I get a "ND Log File could not be generated" message and then on first render, the sim drops to 1 FPS and stays there. Not sure the two issues are related, and not sure what to do about it...   FYI I have tried to uninstall and reinstall the plane. No issues running the PMDG 747 and the QW A787. Using TrackIR, EZdok and latest FSUIPC.   ---   Har
