    Hello everyone!😁 I bought X-Plane 11 about a year ago, I have been flying ever since but except for the Zibo I was very disappointed. I do not like how X-Plane 11 looks and I'm Not happy at all about the aircraft addons of X-Plane 11. My main interest in flying is commercial aviation. I always looked at P3D streams with envy, I just love the crispiness of the graphics (I'm sorry if you don't understand what I mean) I also like how P3D looks a little dark all the time. but of course what I'm really interested in P3D is the aircraft addons and the better weather. I ordered a Honeycomb yoke a few days ago It is currently on It's way. I know that Microsoft will be releas…

    Hi all, I've been researching ATC addons for a while now and have narrowed the choices down to PF3 or Pro ATC. I'm just wondering if anyone has any useful insight into which of these is best and why. I've read a few threads but most were over a year old and there's very little I could find on comparing these two specifically. Any thoughts?

    Just used the internal Prepar3Dv4.5 <Flight Planner> and checked out the Flight Log. Noticed that all distances are in kilometres - why? In my settings I have the hybrid system checked, so - feet, hectopascals (mllibars). There are a few countries that use metres, Russia springs to mind. So why are (kilo)metres used in the Lockheed Martin product? Perhaps a hangover from FSX (but that,too, is an American product). The real question for me, is there a way to edit the Flight Log distances to reproduce in nautical miles, the most used navigation distance scale? I can't find a specific settings section for Flight Planner anywhere,but experience tells me I…

  5. So I really want to get the FlyhtemaddogX for P3Dv5 since I'm upgrading to that platform as well soon but when I read that the MINIMUM vram requirements are 8gb I quickly hesitated since I only have a GTX 1660 super 6gb card. It really is asking a lot from users to buy 8gb+ graphics cards just to use certain add-ons and I won't upgrade my gpu for at least a year or so. If one were to use the MaddogX in 1024 texture resolution with only active sky and not other add-ons, would it be possible to use a 6gb card only? Does anyone have experience with the MaddogX in P3Dv5 using only a 6gb card? Any feedback would be useful. Cheers!/Andreas

  7. Hi everyone, I'm hoping for some support here, as I'm honestly quite lost right now. Up until a few days ago, I was flying around without any issues in P3D v4.5, all of my settings being unchanged for months and using all sorts of add-on planes, scenery, weather, shaders, textures, etc. Everything was looking beautiful and I was enjoying it a lot. Without changing anything in the sim, I suddenly experienced a massive drop in FPS (to < 15) and blurry textures in scenarios that were no problem before. This issue unfortunately still persists, despite my desparate attempts to narrow it down. This is what I've done since the problem appeared (in the foll…

    I´m new to P3Dv3.4 (no money for another PC) So most of my stuff from FSX works very well. I also installed HIFI ActiveSky for P3Dv3. Since them I lost all my airplane lights , beacon, strobe, nav, ldg, Then I de-installed Active Sky and bingo. Lights are back. I noted that during de-install AS says "replace your shaders" or something like that. So how can I have my lights and AS? Peter

    Greetings, I have run a clean install 3 times and my airport textures are strange. At the default KRND, the runway is showing concrete runway on top of a asphalt runway. The taxiways are partially covered in grass. In Seattle, the runways look fine from above, but appear to be covered with grass in areas of it. Has anyone seen this? Been this way since my first install. Rick

    At FSSI we have been doing quite amount of R&D and accomplished AIs to follow Sloped Runways in P3D This is an initial demo for P3D v4.5 only for you to test. The DLL installed just works with the terrain and AI to accomplish it. It is a BETA version still. To install the addon, download it from here, and unzip the folder into the %USERPROFILE%\Documents\Prepar3D v4 Add-ons folder. For more information see how to do this. We are working on an overhaul of the ATC/AI engine. More news to come. Feedback is appreciated. Thanks Federico

  16. Anyone else getting these errors and crashes when interacting with the ATC menus? Happens every time I use them, usually I get through a minute or two of interactions with the ATC menus, and then I get the error. I also notice the ATC menu flashing every few seconds while it is up. This happens with the default aircraft and with the A2A and RealAir aircraft I have tried. The only stuff I have installed are Orbx Global and open LC packages with Orbx Trees HD and a bunch of Orbx NA airports, and ChasePlane to run Trackir. No config file changes yada yada - sliders are not maxed at all. This is with and without TrueSky running. If some folks haven't used the A…

  18. I have tested several different planes to see if I could pinpoint the cause of this issue. My scenario for this test is: Departing Orbx CYBD, heading 051, after about 5 miles away from the airport my sim will freeze. It happens in A2A C172, Default P3D planes and PMDG. So i don't think the issue is related to that. If anyone can do the same test and report back to me if they get the same, I'd like to know. My typical addons are Orbx Global Base, Trees HD, Buildings HD, TerraFlora v2, NA PNW, NA Fjords, Orbx CYBD.

    Hi Was preparing to make the switch over to v4.5 (from FSX) while waiting to see MSFS2020 brings, just as v5 was announced, so decided to wait and see how it was being received by more experienced users of the Prepar3d platform. After following many of the v5 threads and seeing a number of users with 8GB GPU's having issues with excessive VRAM usage, I began to question whether or not v5 would be a sound decision in it's current state and recognizing the limitations of system hardware. System specs: i7-8700 CPU 32 GB 2666MHz RAM Nvidia GeForce RTX2060 Super 8GB Founders Edition GPU Screen Res. 1920 x 1080 Refresh Rate 60Hz (No VR / 4K …

    Well been trying for a month but V5 is not working out . Probably because I have not got an 11gig card . My main use is Vr . With an 8gig card you are playing a balanceing act all the time hoping the card des not crash . Truesky does look nice but not great . To be honest it is off all the time to high a vram . I have one jetliner the 747 everything else is in the repair hanger . If they come I suspect vram will be too much . The beta of TFDI 717 shows me that. So thinking of going back to 4.5 until LM fix the vram leaks or I can afford a 11gig or higher card. The visuals and benefits are just not there. The pain is .
