Hi guys,I tested FSX on three different OS and came out with some interesting results.

I think it is good, but need to wait for another release with an update, seem to find some bugs.

Win 7 has a lot more CPU lighter interface. It has a more friendly build and allow for even the slowest computers to run fairly well without windows bottlenecking them.
