  1. In the last few days every time I launch P3Dv5 it requires all my Orbx products to be enabled (a succession of Enable Request Boxes). I am running P3Dv5 HF1 and I have uninstalled and re-installed the Orbx products, but no change. Also, Orbx themselves cannot help! Anyone seeing this? Anyone got any ideas on how to solve this?

    I've never grown tired of the Real Air Duke in FSX or Prepar3d, and it remained one of my favorites in v.4 of Prepar3d. Having just installed Prepar3d v5, my aim was to add the Duke v2 to the new sim. When I last installed the Duke in Prepar3d v4, I used the instructions uploaded by Mike Lab on how to use the FSX installer to install the aircraft and its related files into the SimObjects/Airplanes folder by pointing the FSX installer to Prepar3dv4 folder. There were also instructions for replacking a sound gauge file in the gauges folder. These instructions are posted in the Tips and Tricks section of this Forum. In trying once again to enjoy this aircraft in …

  10. Hello - I just recently purchased the p3d v4 upgrade for the Majestic Q400. I spent some time watching some tutorials and got everything working great, except for one issue. I can't get the nose wheel to turn on the ground, so steering is impossible. I do have steering activated in the cockpit, so that should not be a problem. I have read several posts all over the place regarding this issue, and have attempted various solutions but I cannot seem to solve this issue. Has anyone here had this issue, and if so, how did you solve it? FYI, I don't have the payware version of FSUIPC. Cheers, Pete

    Excuse the cell phone video. I just did a test flight and quickly wanted to get a video of this cloud flickering problem. I have tried various settings, fresh Windows install, different drivers, etc. The clouds intermittently flicker like this about every 5-10 seconds and it ruins the flight when cloudy. Any ideas to resolve the issue?

    Boy is this ever frustrating! Any CTD's which where declining for me and on the increase again. I have tuned my system pretty well turned down several sliders so really getting great performance. Best I've seen. Period! So what I notice about the majority of CTD's is that they occur on the run up to take off. Its had to say but perhaps just as a wheel is leaving the ground. So I recall that there was something new in the list of new feature pertaining to ground contact. I wonder if anyone else can corroborate?

    Well during the course of tuning P3D V5 I've come to the conclusion that 11GB of VRAM is not sufficient for V5. Everything else on my system is. I am looking to maintain a frame rate of 24fps with 24hz for smoothness and I can easily achieve that with literally all of the desirable eye candy tick and/or to the slide to the right. With that in a typical scenario for me, If I turn Vsync off I see about 30+ fps so performance for 24fps is not a problem. But I am triming for VRAM. I've seen it eat over 10GB of the 11GB on my Overclocked 2080ti.😭

  15. I forgot to put a note here but the development of CNV9 Neuville with a sloped runway is done and the file is on the library since april 25th 2020 under the name Neuville_CNV9_v3. It's an update of the version 2 by JP Filion that had flat runway. The airport ground was reworked to achieve the correct slope for the different parts of the runway. The runway was also extended for the last work done by the airport owners at fall 2019. New hangars are also represented. Landclass around airport modified to better represent the high trees on the approach to runway 24. More realistic and challenging. Take-off run runway 24 Short final runway 24 with high…

    Hi, I have decided to release "AI2UTL Injector" as a public beta. It has been tested in a small group, but I don't want it to release it as RTM version yet. AI2UTL is a tool with which you automagically can replace Ultimate Traffic Live repaints with FLAi repaints and/or individual repaints of Alpha-India, WoA, etc. During the replacement process the aircraft model is validated/checked for usage in P3D V4 (MDLX & PV20 models) For your own pleasure (and mine), please read the whole manual, since AI2UTL will not run out-of-the-box. To state the obvious: You need a copy of Flight1 Ultimate Traffic Live (pay-ware) You can get it here: Micro…

    Just curious....what's your LONGEST flight in V5? I've tried some of the 737s, 757s, I've had and used in P3dv4.5 and in every case....the flight becomes a "stutterfest" before 100 miles from destination. I'm usually at Fl30 or so and everything looks great up until the last 1/3 of the flight. Say KPHL (Philly) to KDET (Detroit). Everything works great close to Erie (KERI) and then the "stuff hits the fan" and stuttering along with outside plane textures and VC start to deteriorate quickly. I usually have to end the flight. I love V5 but 4.5 never did this to me. Starting to get a little concerned. Stan

  19. So I've encountered a strange problem and I'm not sure what has started it. I could swear I used to have trees in among the buildings in my sim when flying in Europe but I don't anymore. I have orbx global installed, no vector. I have verified the files, made sure all orbx stuff is up to date. I have played around with the scenery library and different priority orders but nothing seems to work. Its even more strange because it seems to be fine in North America, but at Belfast, Heathrow, Amsterdam, Paris I have no trees. Whereas at Newark I do. Yet in the European airports I have autogen buildings just no trees, except tiny clusters of them that seem to appear on hills. An…

  20. *This may be the dumbest post on Avsim yet, but this is my true experience.* So, like most people with a mid-spec PC (see below for specs), I was struggling with FPS at places like ImagineSim Atlanta and FlyTampa Toronto. I figured that since dynamic lighting is FPS intensive, I should keep those sceneries on polygon lighting. In P3D settings though, I had to keep dynamic lighting on for the PMDG NGXu's landing lights to work as designed. One day, I went to the FlyTampa forums to see how to resolve the lighting polygons appearing and disappearing at certain view angles, and didn't come to a satisfactory conclusion. So for a laugh, I decided to turn on dynamic li…

    I'm curious what LM is doing regarding this problem. Using the only official release i have (PMDG 747) I'm noticing huge inconsistencies with dynamic lighting. Well lighting in general. But flightbeam airports, Imaginesim ATL, FSDT MEM. Probably others. Dynamic lighting is not working at all on the aircraft. However I've used a few other airports with dynamic lighting where it does work. Everybody seems to be saying it's a V5 problem. What's the story here? Finally, there are some DL situations that nail my fps. When typically i'm able to maintain my locked 30 without problems. Ever. But in these DL sceneries if I move under a spot where there is DL, my fps go…
