Cause: Network latency between client PCs. Fix: Ensure all machines run the exact same build (4.0.23.21468) and use a dedicated gigabit switch. Disable IPv6 on the visual channel network. Prepar3D v4 Professional Plus 4.0.23.21468
The 64-bit engine allows the sim to leverage all available system RAM, enabling much higher resolution visuals, increased autogen draw distances, and more complex data-driven scenarios. Key Features of Prepar3D v4.0.23.21468

While newer versions like v5 and v6 have since been released, the v4 Professional Plus 4.0 build remains a landmark for its stability and broad third-party add-on compatibility . The 64-Bit Revolution
By moving to 64-bit, Lockheed Martin ensured that Prepar3D remained the industry standard for professional flight training, providing a scalable platform that continues to evolve with current hardware capabilities. Fix: Ensure all machines run the exact same build (4
As the first 64-bit version, v4 requires a modern system to perform optimally. License Options - Prepar3D
In the world of flight simulation, few release numbers carry as much weight among serious aviators and simulation enthusiasts as the transition to 64-bit architecture. While Microsoft Flight Simulator (2020) currently dominates the headlines, there remains a massive, dedicated user base reliant on the stability, extensive addon ecosystem, and professional utility of Lockheed Martin’s Prepar3D.
The shift to 64-bit is the defining feature of v4. Unlike its predecessors, which were capped at 4GB of Virtual Address Space (VAS), this version allows the simulator to access significantly more system memory.
