Prepar3D is a spin-off from the Microsoft ESP platform and originally released in 2007 by Lockheed Martin after they bought the rights. Prepar3D brought great things for users of Microsoft Flight Simulator X who wanted to port all of their existing add-ons over to a more modern and advanced platform as it was backward-compatible with FSX add-ons.
In 2017, Lockheed Martin released Prepar3D v4 (P3Dv4) which brought the binary and all associated modules up to 64-bit. While this limited the library of older FSX add-ons that were compatible with it, it opened up the platform to more advanced and sophisticated mods along with improving the actual sim engine itself - gone were memory limits and associated nuances of a 32-bit platform.
Many previous FSX users have shifted over to P3D because of the modern design of the system. The sim improves graphics, lighting, weather along with many advanced features with a completely new SDK enabling developers to create add-ons that are next-gen.
Given the release of the new Microsoft Flight Simulator imminent, we can still expect users to stay loyal to Prepar3D - much as users have been with X-Plane.
