Fixes, Improvements, and New Features
Flight simulators are a significant part of the digital aerospace industry, helping pilots train, developers innovate, and enthusiasts explore the world from their computer desks. The release of Prepar3D v5.4 (220.127.116.11482) is a significant step forward in the development of flight simulation software, boasting a host of new features, bug fixes, and overall improvements to its predecessor.
General Application Performance
One of the most crucial aspects of any flight simulator is its performance. The Prepar3D v5.4 has addressed this with major improvements in the general application performance. Thanks to enhancements in the background thread performance, users can expect a smoother, faster experience with less lag and stuttering.
GPS and Flight Planning Systems
The flight planning systems have been thoroughly revamped, allowing for more control and flexibility for add-on developers. Three additional backend flight plan GPS systems have been added, allowing for staging, secondary, and offset flight plan systems. This will give pilots and developers more control over their flights and improve the overall realism of the experience.
For those using VR systems, Prepar3D v5.4 provides a series of VR-specific fixes and improvements that simplify VR setup and calibration, enhancing the user-friendly nature of the system. The update even includes support for mirror texture with Varjo HMDs, enhancing the visual experience when using VR.
Bug Fixes and Stability
Addressing issues identified by the community, a multitude of bug fixes have been introduced to increase the stability of the application. Issues such as a startup crash that could occur with MSAA and Enhanced Atmospherics active, as well as a crash when calling SimConnect BeginVideoStream, have been fixed. This version even fixes issues that prevented render to texture views from drawing in HTML5 panels, which will significantly improve the user experience.
Flight Plan Enhancements
Flight planning has been significantly enhanced, with fixes and features including improved identification of the final approach fix at flight plan load time, and the addition of GPS vars to reload procedures. This allows more flexibility and control for pilots, improving the overall flight experience.
Multiplayer and Networking
With the introduction of improved network traffic handling and fixes for multiplayer issues that could cause disconnects with large amounts of network traffic, multiplayer experience will be enhanced. Prepar3D v5.4 also brings the addition of a VR setting to auto-restore tracked origin, ensuring that multiplayer VR experiences are as immersive and enjoyable as possible.
Professional Plus Only Fixes
The professional plus version also includes a range of enhancements, including DIS relative timestamp fixes, improvements to SimObjects incorporating their simulation time when calculating DIS relative timestamps, and fixes to a bug where entity state PDU would broadcast before the position had been set.
Prepar3D Content and SDK
The new version also includes several enhancements to Prepar3D Content and SDK. With active arrivals and departures now drawing by default in the p3dgps gauge, a more accurate and intuitive flight planning experience is assured. Additionally, platforms can now be flagged to apply or disable curvature during elevation queries, providing more realistic and detailed scenery visuals. In conclusion, Prepar3D v5.4 offers significant improvements and new features, providing a more immersive and enjoyable flight simulation experience. Whether you are a professional pilot, a developer, or an enthusiast, this version is a worthwhile update that enhances and elevates your virtual flying experience.

How Does It Compare to Microsoft Flight Simulator?
As we dive into the extensive changelog for Prepar3D v5.4, it's crucial to make a comparative analysis to its chief rival in the field: the latest iteration of Microsoft Flight Simulator. Both platforms strive to provide enthusiasts with a realistic, immersive flight experience. Yet, the distinguishing aspects lie in the details of their individual enhancements, which determine their respective appeal to different user groups.
Prepar3D v5.4 brings a multitude of performance, stability, and usability improvements. A key one is the enhancement in background thread performance, which signifies faster loading times and smoother operation. In contrast, Microsoft Flight Simulator's last update focused more on visual fidelity and real-world accuracy in scenery generation.
Another noteworthy enhancement in Prepar3D v5.4 involves the GPS and flight planning systems. With the inclusion of three additional backend flight plan GPS systems, there's greater flexibility for add-on developers. This surpasses Microsoft Flight Simulator's current feature set in the same area, providing a more nuanced control to the developer community. Prepar3D's updates also highlight its dedication to a better simulation experience with the resolution of multiple bugs identified by the community.
For those using virtual reality (VR), the release of Prepar3D v5.4 is a step forward. VR fixes and improvements promise a more intuitive setup and user-friendly calibration, aiding the immersion of the user into the virtual flight space. While Microsoft Flight Simulator's VR experience is also commendable, the Prepar3D update shows a more focused approach to refining this aspect.
From the technical perspective, Prepar3D's Client installer is required for most of the present fixes. Although the Content, Scenery, and SDK installers are optional, their usage might enhance certain areas of the simulation. In comparison, Microsoft Flight Simulator adopts a more unified approach, delivering updates via a single package.
Ultimately, the choice between staying with Prepar3D or jumping to Microsoft Flight Simulator lies in the hands of the user. If you appreciate a more community-driven, developer-friendly environment with robust GPS and VR systems, Prepar3D v5.4 is a compelling choice. Yet, if visual enhancements and real-world scenery accuracy are your top priorities, Microsoft Flight Simulator may be the way to go.
