  1. Hi there, I am running prepar3d with the PMDG add-on for 737-800. The tanks are always full and I cannot adjust the fuel amount in the tanks. If I insert "0" or any other value in the fuel menu, the amount is readjusted, but if I return to flying, I still have full tanks... Any help is highly appreciated! Greetings Berni

  3. Hi everyone, Before making a big mistake, I would like to have your opinion about an issue on Prepar3D. I changed my nVidia 780 GTX few months ago for a 1070. After the release of the latest P3D hotfix (v3.4.22.19868), I decided to invest in a second graphic card. I didn't expect a huge FPS increase, but, at least, few more fps, in particular with complex sceneries and AS16 clouds. And well ... the results are not what I expected ... It's even worse ... I run a homecockpit based on a main P3D computer (and with 3 more computers for hardware and Prosim737 software) : 3 x 1920x1080 monitors with a i7 4770K @4.4Ghz, 16GB RAM, 2 x 1070 GTX (MSI and KFA²,…

  4. I keep looking at P3D v3 and thinking I should really move over from FSX to take advantage of the latest improvements. I believe the PMDG JS41 can be moved over but has some autopilot problems so I would like to retain FSX on my system for this aircraft alone until PMDG make the aircraft P3D compatible. My question - can P3D and FSX work happily side by side on the same computer ?

    Don't mean to hijack this thread but how does this Dolby cockpit sounds work with add on aircraft such as the PMDG 737? Or is it only meant for default aircraft? I already have TSS's sound set for the PMDG 737 but it is annoying that it's only 5.1 and only in exterior views. Thanks in advance. Regards,

    A sudden jump in my FSX loading time (initial load with a fresh PC boot up) recently shot up from 2 minutes as normal to a whopping 9 and a half minutes. I aleeady had FTX England, Scotland and Wales installed, but prior to the new loading time I had just installed Orbx's PNW and Northern California. I assume these a responsible for the jump. After switching these two new sceneries off on the sim and removing the folders from the FSX root directory, I am back to 2 minutes load time. Now I don't know how to proceed. Put just one of the sceneries back in and fly it first.... swap out my UK Orbx sceneries for the American ones .... try both the US sceneries again, see i…

    Hi all, been out of the flight sim loop for a while. Decided to give 3.4 a try and along with PTA and couple other tweaks I've to say it never looked better. However I keep running into OOMs on approaches, even with low-medium settings and such. I noticed though my Ezdok has an issue where everytime I switch to the outside cameras it kinda reloads the whole picture if you know what I mean. Also it has to always skip through the world cam before getting to the aircraft cam so I'm not sure if thats causing some sort of weird memory leak but I heard it mentioned on some other threads. Someone suggested deleting the camera.cfg and letting P3D rebuild it as well as rerun …

    I've noticed a weird fps drop on my system. If I load the FSL A320 at the gate in Gatwick, after 80% loading I see a preview which I can pan around using ezdok which I get 30fps. After loading is done, the actual sim gives me 15. Is this normal? Can I fix it? thanks.

    Did an uninstall reinstall of P3D 3.4.22.19868. Loaded up my PMDG aircraft and low and behold, no request for my activation code and the sim behaved strangely: mouse clicks not working, etc. Asked over there and they told me SimConnect issue and how to go the redist folder and execute the 3 msi files, which I did. Didn't help. Uninstalled and reinstalled the aircraft and same issues persisted. Look in the Programs and Features area and no SimConnect. BTW, when I executed the msi files (right click, install) virtually nothing happened-a quick flash and that was it. Didn't seem like anything was installing. Any help would be appreciated. Thanks.

    Hello everyone, I have a issue where my addons from my addon menu bar do not work at all, this includes FSUIPC, GSX, EZDOK etc however i can see them on the list. I first encountered this whilst climbing out of Heathrow in the FSLABS A320 and the aircraft fell out of the sky with my camera view stuck - i have done over 30+ flights with P3D V3.4. That day i had installed Aerosoft Holiday airports V2 + Flytampa athens with EMT. My first flight that day was perfectly fine until i recieved an NTL.DLL error when stretching the GSX menu to select my gate, after the restart i did the return flight as mentioned earlier out of Heathrow when it first happened.

  19. A new version has been developed with many many enhancements and fixes to the vegetation and urban structured areas. Due to the many months of work to improve the accuracy of a number of locations the file size reflects this, 9GB compressed, I think currently it is 3GB. This version is now 3.0 and I’m sure you will enjoy NZ in its fullness. If you have any questions about compatibility with other scenery i.e Orbx and how to enable this scenery whilst maintaining the beautiful scenery such as airports then I can assist you, just throw me an email. The new download is available from my website www.nzscenery.co.nz. I am charging for this version due to the many m…

  24. Currently I use Navigraph for my charts on my iPad when I am flying. Is there something that would allow me to enter my flight plan and show it on an interactive map with weather? Or is Navigraph able to do this? I'd prefer to use my iPad but if there is something I can use on a PC that works too. I've seen it on YouTube but can't figure out what application it is. I can pull up charts, and maps on Navigraph, but not full flight route with my flightplan. Thanks!

  25. Hi all I really need help as I want to avoid reinstall of sim due to plenty of addons. I was using MT 6.0a without any issues with my P3D. Today I installed EIDW freeware scenery (Dublin) which had its own installer. It was created for FSX but with a little help of ADE I fixed the taxiways and all worked fine. Not sure if that installation had any impact, but suddenly my MyTraffic 6.0a stopped to show the amounts of traffic it showed in the past (for e.g. with 25% slider of Airline Traffic I had around 80 planes in certain scenario. Now I have 3-5 max.) I tried to reinstall MyTraffic 6.0a but it didn't solve the problem. EIDW scenery I installed has no un…
