    Can someone help me with getting the much admired Real Air Duke (v2) installed and working in v5? I have the FSX installer for this aircraft, and it has worked great in Prepar3d v4 after I used Mike Lab’s instructions for steering the FSX installer to the Prepar3d folder and replacing a sound file in the aircraf’s gauges folder. But when I try this process now with Prepar3d v5 as the install target, the installer fails to work because it can’t establish an internet connection. I assume the links in the installer are just old and broken as RealAir is no more. But I see others are using the Duke in v5. Can I simply copy the files from the Simobjects/ airplanes …

    On July 10th John Venema announced the work would very soon begin on the long awaited P3D/FSX opus. Holger Sandmann is now leading a parallel team to work on OLC Asia and work will commence in earnest in the next week or so and we're aiming for a release well before years' end. Today he announced openLC Asia has not been started on yet and at this stage the project has not been given the green light. We've been waiting for 3+ years since the first announcement of OpenLC Asia. We know now that we'll most certainly never see it. It wouldn't make sense to put on the market around the time FS20 is released. Having been among those requesting OLC…

    Hey all/any P3D veterans. Does anyone have any detail on what it takes to develop an addon for P3D? - v5 specifically. I'd quite like to port https://github.com/mSparks43/XPlane-11-AutoATC-plugin Over to it, but really don't like the FSX style development environment, I see they have a $10 a month for a developer licence - does anyone know what this provides and who to talk to for more detail? Is it anything more than you get for X-Plane for free?

  7. 1.) I have been running tests today, flying the Extra 300S, I have come to the conclusion, that with really good or BAD weather set, and multiple cloud layers, that the new atmospherics is WAY WAY better FPS! Maybe it is all pushed to the GPU now? It really does seem so, as I am running 2080ti and its handling it superbly. If I turn off advanced atmospherics in bad weather, I actually DROP 10-15 FPS! It goes back to the CPU? 2.) I was reading at the LM forum and stumbled across the P3DV5 min specs, and noticed they actually recommend windows 10 build 1909. I was running an older 1903 build. Could all be placebo affect, but since updating it, and running the l…

    So I have v4 and v5 together on my PC. I upgraded to the latest Nvidia driver. And now there is a performance push also in v4 that is substantial. Anyone else seeing this? Can the driver alone do this? Is there anything v4 and v5 share somewhere? Seems to be completely bogus, but I wanted to ask just to make sure that I am not hallucinating.

  9. I have started to update my P3D v4.5 Professional with hotfix 3. I have installed the Client with no problem, but when I try to install the Content.msi I get the following message: the file`fil08F88902310E1B4E31B7C3C25470F009`cannot be installed because the file could not be found in cabinetfile `cont1.cab`. Then the install process goes back to start and stops. I have downloaded the cabfile twice, but I get the same message, What can I do? Tor Arild Danielsen

  11. Hi, So far i have only come across FSDreamteam who manage BOTH a P3dv4 and P3dv5 solution at the same time without issues. Meaning you can have both sim version installed without issues. Some scenery developer like Flytampa (this is not meant to downgrade or put fingers) has the same SODE entrys folder structure which can complicate things. They are looking into it , so this info is just for you who has issues when trying to install into both v4 and v5 . (it can be done but see this https://www.flytampa.org/forum/viewtopic.php?f=28&t=13846 ) Michael Moe

    Hello You have to see it to believe it. I have watched a live stream on YOUTUBE by Adam J Pestridge who claims that he has found a "secret glitch" within P3D v5. What he did on live stream was to exchange the P3D.CFG files between V4 and V5. The "Secret Glitch" was that it doubled the FPS from 30 to 60 and he even commented "I wonder if Lockheed Martin are aware of this" Such actions should not be allowed on live stream Clive Alexander

  14. I have used multiple ORBX sceneries (several Regions and individual airports, trees, etc,) in Prepar3d using the older Orbx Central manager tool. Now the question is how to get this compatible scenery into Prepar3d v5 with least complexity and waste of time and disk space. I have retained my Prepar3d V4 setup on the same drive where I am installing v5. My Orbx sceneries for v4 were installed directly in the v4 application, not in the more modern method of creating libraries outside of the application. I understand that the one goal of the revised ORBC Central is to get users to migrate their ORBX installation away from the inner workings of the app and…

  18. JustSim has done it again. They made a post on facebook saying: "We have negotiated with our publisher. The airports of Santorini, Gazipasa, Brussels and Palma de Mallorca will receive a free update for the P3D V5. Other products will receive an update for a symbolic 5 euros. I urge you not to write negative comments here, this is the policy of our publisher." They charged for V3 minor updates. They charged for V4. They charged for V4 updates. Now they charge for V5. I find it ridiculous, I have over the years bought a number of their sceneries, and even after complaining I bought a few of the 5 euro updates. Today marks the end of my purchases to Just…

Wasted 2 days trying to get to work . Hopeless please add VR users to the beta testing pool in future . Bad show LM . Yes I have adjusted settings sliders and the setings to get it to work are not worth flying with . 3 days and giving up till LM hopefully make things work . Love throw money away. At least I did not uninstall V4.

  21. I am presently in a cross country real-time flight between Ganges, B.C. and Flint, Michigan. Because at the moment I can't inject live weather, I am running this cross country flight with the Building Storms scenario. Over the last two days, and with many, many start, observe, tweak/massage settings across graphic genre/end flight and repeat, I have some usage-observations for you; Firstly, you do need no less than 8 GB's of vRAM, **IF**, if you want to run the sim pretty much maxed out. If you choose to run each slider and feature that can be adjusted, at 80-100 percent of that feature's range, you will consume usually at the start of your flight and loading in,…

  22. Hi! Now that V5 is out with updated mesh and airport data I wanted to check for the need of a 3rd party mesh addon or any elevation corrections (like Vector provided). This was my setup up to V4.5: - Mesh: FS Global 2010 - FTX Vector to provide the AEC (Vector therefore had its own set of airport BGLs, which was horrible regarding updated navdata!) - Herve Sors updated stock airports in combination with FSAerodata to update other navdata (Again: It was a mess regarding the Vector and some LC airports!) My plan for V5, which may come true: - No need for an addon-mesh, or if using one, no need for airport elevation corrections (airport position should…
