Nicht lange nach dem Release von Version 5.2 hat Lockheed Martin jetzt Hotfix 1 für Prepar3D veröffentlicht. Dieser adressiert vor allem Crashes grafischer Natur, aber auch die Performance von Szenerie- und Autogen-Elementen soll laut Lockheed Martin verbessert worden sein. Zur Installation des Hotfixes reiche es laut Lockheed, nur den Client-Installer auszutauschen. Des weiteren könne es vorkommen, dass eine erneute Aktivierung des Sims notwendig ist. 

Außerdem empfiehlt Lockheed die „Delete Generated Files“-Verknüpfung im P3D-Hauptverzeichnis nach der Installation des Hotfixes auszuführen.  Hier könnten allerdings Einstellungen verändert/resetet werden, die Add-Ons betreffen  – in diesem Fall empfiehlt Lockheed das Löschen der VolumetricClouds.cfg im Verzeichnis “%appdata%\Lockheed Martin\Prepar3D v5”, da der Hotfix auch Veränderungen in der Wolkendarstellung adressiert.
