The transition to a 64-bit architecture is the defining feature of this release. Previous 32-bit versions were constrained by a strict 4GB Virtual Address Space (VAS) limit. High-fidelity add-on aircraft and complex scenery often triggered Out-Of-Memory (OOM) crashes. Prepar3D v4 Professional Plus 4.0.23.21468
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.
refers to a specific build of the landmark v4 release of Lockheed Martin's visual simulation platform. Released in May 2017, Prepar3D v4 was the first version to transition the engine to a 64-bit architecture , effectively removing the "out-of-memory" (OOM) errors that plagued 32-bit simulators like FSX and earlier P3D versions.

Conclusion
This update refined the dynamic lighting system. Unlike traditional baked-in light textures, lights in this build interact realistically with aircraft hulls, wet runways, and airport scenery. It introduces authentic ambient shadowing and accurate night-lighting dispersion. Performance Optimizations
