Could not agree more here. 15 years in and I am still amazed how great FS9 is for simming. I get 60 FPS and smooth as silk, and all the add-ons, aircraft and airports, are great. Only real issue I ran into recently was on some FSDreamteam Hawaii airports, can't download them and even that's apparently cause I have windows 8.1. But otherwise, long live FS9
