I am so glad I came on here after struggling with this issue this morning. All I wanted to do was connect Pilot2Atc to the sim and though I can do that and it works brilliantly thanks to fcuipc7 the performance drop makes it unplayable. Pete, I thank you for your tireless efforts to find a solution (or at least finding out where the problem lies) and can only hope we can enjoy the sim more with the update. A lot of wrinkles need ironing out. Like many I feel I have paid for the privilege of being a beta tester. Does make me wonder what the beta testers were looking for. Many of them can't have been flight simmers.
