Lockheed Martin Releases Prepar3D V4.2

P3Dv4.2 Released 2 SmallWatermark

Since the release of Prepar3D v4, simmers have been enjoying using the ESP-powered sim in a 64-bit environment. The new sim from Lockheed Martin brought a bunch of new features including dynamic lighting, virtual reality and improved weather effects. The first update, 4.1, saw a few improvements to these areas. However, today, Lockheed Martin has released Version 4.2 for simmers to download and enjoy.

The Prepar3D V4.2 update brings a huge change log, some of which will really excite most users. Dynamic lighting has been optimised further to help users get satisfactory performance. According to the change log, “dynamic lighting is now LOD based on distance and size on screen”. Lockheed Martin has also worked on ensuring that users see less blurry textures in the sim also by “improvements to terrain paging performance”. For helicopter users, Lockheed Martin has been listening and included new capabilities for them. This includes scenario controllable artificial intelligence and autopilot functionality.

A lot of this update includes additional fixes to the Virtual Reality elements of the sim. This includes the ability to select the headset in the VR menu, fixed flickering issues, added additional error messages and fixing the left-eye lag seen in Oculus Rift VR headsets. There’s a whole bunch of fixes.

Furthermore, Lockheed Martin has also updated the PDK to include new objects which can be placed in the sim as well as integrating a brand new Voice Control plugin and service to add custom voice commands to the system. How developers use this going forward will be exciting!

Other random fixes include fixing time zone issues including updating GMT references to UTC, updating daylight savings time dates, fixing default time zone locations, and fixing international date line behaviour, fixed a crash with Ultra Water when using third party add-on aircraft and performance for render-to-texture (RTT) views and plugins in SLI.

The Client installer is required for Prepar3D v4.2, however the ContentScenery, and SDK installers are optional. You must first have Prepar3D v4 installed to utilize the Client only installer. To install the Prepar3D v4.2 Client, you must first uninstall the previous Prepar3D v4.0/v4.1 Client through Programs and Features in Windows Control Panel. The Prepar3D v4.2 Clientupdate will require you to reactivate your product, however if you have an internet connection it will be automatic. For more information please view the Prepar3D v4 Download/Installation Instructions from the Downloads page.

Don’t forget, some add-ons may not be compatible with P3DV4.2 straight away! You may need to wait for updates before doing so.

Brace yourselves! We’re about to get a flood of addon releases. Certainly, no coincidence a bunch of add-ons have been delayed for this update.

My mind automatically goes to Aerosoft and the Airbus collection. lol

Is it only me or there is a clear demonstration that P3D is focusing on improving the military training applications and overlooking a bit the most fundamental issues, not paying much attention to the civil aviation aspects of the simulation?

No Carlos and “lol”, I imagine that when LM reach the point of being able to “license exclusively to the military and the like”, then at worst, all that happens is a new version of P3D version ‘n’ will be released for them. It will not mean that current end users will not have access to P3D.

Just like FSX and FS9 before it, P3D might become a platform that has no future, but for the next year at the very least, it has a great development future.

Q: If it was always designed for the military, why bother with 3rd party relationships with ORBX, Aerosoft and the like who provide ‘eye candy’? The military isn’t interested in pretty textures, they only want approximate representations of locations, but with accurate terrain and physics modelling.

Very well said “lol”… Finally someone who seems to understand the whole business about the P3d! That’s also why I prefer to use the old FSX and probably will only replace it with the X-Plane…

LM always have maintained their market is commercial and industry. you as the flight simmer are not part of those plans. why is this news to anyone is beyond me. when LM reaches the point they can license exclusively to the military and the like, you will no longer be able to obtain the sim, just like you cannot obtain a lot of sims from naval to excavator trainers.

consider yourself a purchasing beta tester and enjoy the ride while it lasts

Yeah I’m happy to pay to have v4 (and previous versions). Its more expensive because people are actually working on improving it. I bought a new simming PC in 2008 to jump to P3Dv2. It was great, but had 32 bit limitations. That exact same computer is now running v4 with not 1 OOM, no studders in/out of PMGD NGX/ASN/REX/ORBX/FSFX into/out of KLGA/KLAX with lots of AI, much faster frame rates, most sliders to the right, improved visuals and constant product support. I respect those that have invested in/stuck with other platforms, but I’m quite pleased with my choice and would recommend it to any simmer. They’ve improved it so much one version to the next that I chose to spend the money to upgrade and I’ve never been upset afterwards. The progression taken in 6 years between V2 and V4 is amazing.

That’s quite the list! I suppose we can even say there *are* loads of changes then 😉
