I've been playing/flying with Flight Simulator before it was Microsoft's product. In this video, I show you the results of my testing with all 4 versions of Flight Simulator that I have. The only reason I don't test FS 5.0 is that I don't have a 3.5 inch floppy drive anymore!
Then a quick look at Microsoft newest version of Flight Simulator.
This isn't a review of the different versions, just a test against Windows 8. If you are a flight sim enthusiast, you have nothing to fear from Windows 8.
