If I can omit racetracks which aren’t in MSFS generally,
I fly IFR procedures without problems, RNP, GPS and ILS. All is enough to me fly them correctly. Also in 172 and also f.ex. with Carenado Seneca. I understand that maybe other features can be useful with msfs devices generally but in this time I can fly all IFR and enjoy it. Who now require that features to not battle with no features use that Community addons, not me from some time due FPS performance.
