When our product was used in FSX Steam Edition (FSX-SE), we verified whether there was a problem.

There are no problems with there for the most part. But it was found that several effects disappear at Nagasaki. There is a possibility related to an environmental factor for that. We distribute correction patch for Nagasaki. If you have a problem, please use it. If there are no problems, it isn't necessary to use that.
