ASX SP2 is now official! This upgrade pack focuses on wind shifts and visibility depiction improvements, as well as fixing several bugs and adding some new enhanced functionality.

In testing, an estimated 80% average reduction in wind shift frequency and intensity has been realized, with 100% wind shift reduction in many cases. New data smoothing, directional control, special FSX interface techniques and layer manipulation has finally made this possible.

This upgrade is offered completely free of charge for all existing ASX users, and the download is available now from the HiFi support page at

Active Sky X is HiFi's latest award-winning weather simulation system for Flight Simulator X and includes too many features to list here!

In addition to the ASX SP2 upgrade, X Graphics Service Pack 2 has also been released which addresses some window layering/pop-up issues especially when used with ASX-triggered graphics installation. All XG users are advised to upgrade!
