Its doing it for me, when uninstalling it the sim is buttery smooth, go to reinstall it and the stutters come back so I even had navigraph do a remote session to try to fix it but although it was slightly better the stutters were still there.
So I have simlink uninstalled, I dont use moving maps , it was only good for taxiing , but I can live without it and for vatsim I can still use the airport charts etc to know where im supposed to be going to a specific gate for example
