Yes. And if your looking to replace a video card a small incremental price increase will get you a much better card now-a-days.

The updates over the last two years have been free... but there are charges for major revisions.

FSOne wants $130.00 for their upgrade. Aerofly wants over $150.00, and Realflight charged only $80.00 for the 3.5 to 5.5 upgrade path ( a real bargain considering you got the add-ons free too plus all of the enhancements. ).
