: Advanced simulation of Night Vision Goggles (NVG), Forward Looking Infrared (FLIR), and Radar.
Prepar3D (pronounced “prepared”) is a flight simulation platform focused on professional training, academic, and enthusiast use. The v4 Professional Plus 4.0.23.21468 build is a specific maintenance update within the Prepar3D v4 generation that continued to refine stability, compatibility, and performance for users relying on this long-lived platform.

The shift to 64-bit architecture was the headline feature, but version 4.0 introduced several other core enhancements that redefined simulator realism: Prepar3D v4 - Key Aero : Advanced simulation of Night Vision Goggles (NVG),
While groundbreaking, build 4.0.23.21468 was a first-generation 64-bit product and thus faced initial teething issues. Many third-party add-ons designed for FSX or P3D v3 were incompatible without updated DLLs. Furthermore, users reported occasional texture loading stutters (micro-stutters) on high-core-count CPUs due to the rendering engine’s reliance on single-thread performance. Lockheed Martin addressed many of these through subsequent point updates (4.1, 4.2, etc.), but the 4.0.23.21468 build remains historically significant as the stable base from which the entire v4 ecosystem grew. The shift to 64-bit architecture was the headline
Included high-fidelity models like the updated F-22 Raptor, F-35A, and various Sikorsky MH-60 variants.
