Games follow time but some games force the time to follow them
There are many ultra realistic aircraft in game created by microsoft corporation and even better addons, it offers many cockpit features from flying an aircraft to control cabin cooler or heater or lights, imagine how many are there in between (better refer to wikipedia, list is endless). Playing this game accurately is a tough job for any beginner, but as time will spend, the hard practice comes to a sweet result. controlling an aircraft, especially a 747 requires your brain and its potential that gives your hands power to press keys. OKHAY, imagine what goes on CPU, this game is sooooo cpu intensive that its demand start from a quad (q9650 or above), duos will fry processing and processing, I mean, will get so confused what to do, low frame rates is a major concern here, even a powerful system comes to it's knees, when talked about fsx.
For everyone who love planes should definitely opt this bad boy.
