  1. Hey guys, I am getting ready to get on board with PE as I finally want to properly sim with ATC and spend less time "setting/tweaking" my sim. Anyway here is the issue For PE you want latest Nav DB and latest Airport AFCADs....now I do know the options like FSAerodata and Hans.Sors (the freeone) and good ole Navigraph updates. If flying airliners with navigraph - then there really isn't any problems but I am planning to fly GA and get some CAT ratings on PE. Here is what I have Orbx all US FTX Regions and US airports - Now with this most of the airports should be fine but what Airac updates? If I use FSAerodata - it apparently has an issue with …

  2. I was pretty sure i saw somewhere a possible cure for this, or at least where in the file system to verify settings arent lost. Every once in awhile i load p3d and all the assigned buttons are mixed up/lost. Does anyone have any tips on where to look to keep this from occurring? Thanks in advance

  3. I spent some time trying to find out what might be happening with regard to Instant Scenery. Over at SimForums there are several treads unanswered for long periods. Not even a clue if this application is dead in the water. I would have thought by now a simple answer would have been possible. Does anyone have any information on this applications status? Bryan

  4. Hello. I did a complete re-install of P3D 4.4 after I had bought a new rig some days ago. I have a slight annoying problem though. the "OK" button on the map is greyed out. I have no idea how to fix that? Google doesn't help much, found one topic at the offical forum but no solution. Thanks in advance.

    Hey, Everyone! I thought I'd put my 2 cents worth in on a very hot topic here at Avsim concerning terminating micro-stutters. Many of you may already have tried this or do it now, but maybe some here haven't tried this simple fix. And it may not work for everyone. It's the "Disable Core 0 and Immediately Enable Core 0" procedure after starting P3D, so it's nothing revolutionary and it's probably well-known, I think. My specs are listed in my signature and I run P3D v4.5 HF2 at pretty much max graphical settings except for low shadow quality. Basically all my sliders are to the right including autogen (draw distance and quantity). In ASP4 I have it set to 20 cl…

    Hello all ... grumpy old me again. I do appreciate that this subject has been covered a lot, but I cannot find anything difinitive to sort out my problem. As can be seen by my computer specs below, I have the Ryzen 9 3900X which I have now overclocked to 4.3mhz all cores On XPlane11 I am getting 55-60FPS out of YBCS using the Zibo 737-900U in P3Dv4.5 I am getting 8-30FPS default aircraft and default airport YPDN. Using ORBX scenery and Aus v2 I can enjoy a cup of tea between frames (ie never exceeds 10FPS until well away from the airport) I was watching core speeds in XPlane and it sits on 4.2mhz most of the time. With P3D it rarely exceeds 3.0mhz…

    Hi guys, I'm interested in getting the RWY26 MKJS for P3D as somewhere to take my Jumbo. The only problem is, the Simmarket description has "static jetways"; does anyone know if these are modelled as separate objects, so that I can replace them with GSX expansion, or whether they're just painted into the scenery, so to speak, with no GSX replacement possible. If I can do a GSX exclusion on the "static" jetways, I'd be interested in getting this. Cheers folks

  12. The real world Cabri G2 helicopter has a cyclic trim switch that sets trim for pitch and bank. My heli model by MP Design Studio works a treat with P3D. P3D has settings for elevator trim up & down and aileron trim left & right: these key assignments work perfectly for fixed wing aircraft. But I can't make them work on my rotary wing Cabri G2. This is also the case with other helix resident in P3D. This is a great nuisance because without the ability to apply trim one has to maintain a constant force on the cyclic during flight. Please can someone suggest a solution?

  13. I've been trying lately to get more performance out of P3D because I'm not sure if I'm impressed by what I get considering my system. My main beef is that I keep reading about P3D v4 using the CPU cores evenly by default and I see other setups which are achieving this. This is not however what I see on my system. I always have core 0 maxed out at 100% whereas all other cores only really get utilized during any loading process but not when flying. Overall CPU usage is around 14%. I used to have HT enabled but I tried disabling it and the overall CPU usage increased to about 24-27% and I see core 1 is getting utilized more, around 25%, which is nice I guess. I also tri…

    Are folks still tweaking the sim1.dll file in order to gain "realistic" ground friction in P3D v4, or are any alleged issues now largely resolved in the latest releases (P3D v4.5 HF2)? I note that Pete Dowson's lua files for friction do not work in P3D v4 and he may not wish to modIfy anything accordingly.

  15. It's a little hard to explain this, but I've had an issue recently where certain objects skew off into other directions. It only works on certain objects, but most notably, the cranes (default scenery). If you zoom in very close to the object, its fine. But, if you zoom out, it skews into weird directions. Almost like an old VHS screen effect This is at KOAK, (default scenery, not using ORBX NorCal) but i also noticed this at PacSim RKSI. The fence near the airport is literally floating in the sky! And, the cranes near the airport are skewed like in the screenshot above. I have had this issue before, but what i did was i reinstalled the Prepar3D Scenery. Then fo…

  17. Having a few odd things going on in my sim at the moment and this is one of them! I am getting a very unrealistic square edge area of no cloud shadow around my aircraft once I get low enough. Does this look familiar to anyone? I have the same cloud shadow settings I have always used and this occurs with or without chaseplane. I have also tried different cockpit clip mode settings being "none" or "normal" Would anyone have any ideas?

  18. Hello All, Recently I've been noticing these giant light balls or street lights during the night which didn't seem to appear before. I've already turned off Orbx Lights (or I think I have) via the executable file that resides inside the Orbx folder which is named ".............Day" but I've not noticed a change. Aside Orbx I use no other lights that I can recall of, and at SBGR (TropicalSim) this is so bad that it even happens INSIDE the airport, in the approns and some taxiways. Does anyone have a cure or suggestion for getting this any better? Thanks.

    AutoStars was originally developed for FSX to update the number of stars shown in FSX. I now use it to update the number of stars and the location of the planets in P3dv4.3. The various features in the program are in the AutoStar manual. The program can be found in the AVSIM library by doing a search for “autostar”. The file name is “autostarx.zip”. Unzip the file and install in the directory and location of your choice. I have it in "D:\Autostar". To start the program just click on “AutoStarX.exe”. I have created a shortcut for it and I also “Run as Administrator”. Before starting AutoStar go to C:\ProgramData\Lockheed Martin\Prepar3D v4 and find the file "…

  22. Hey Guys, Have a problem that I just can't figure out, and hoping some of you might have seen this, or know what's causing this. I have had FSDT's PHNL for ages, all this time working fine. When I installed OrbX Honolulu, I started getting Kernelbase.dll crashes upon loading at PHNL. I load with the default F22, it always CTD'es with a kernelbase error, as per the Event Viewer. I googled to see if I could find anything about a Kernelbase.dll error specific to PHNL, both as FSDT and the OrbX forum, but came up empty-handed. Finally couldn't figure out what was causing this, so I did a couple of things: 1) I uninstalled both FSDT PHNL and OrbX Honolulu,…

    After installing ORBX Global HD Buildings, I saw a huge dip in my FPS.....down into the teens most of the time. I have almost everything ORBX produces, and I have REX Environment Force, AND REX SkyForce. I use Active Sky for P3d for weather. My computer is a recent Jetline Build that is about the best one they make....and I've enjoyed great FPS, usually in the 40's and 50's with all the above. But after installing, then deleting, and reinstalling Global HD Buildings, my FPS was way down in the teens.and stuttering often. The magic fix for me, which is often stated on this forum, was to rename my old config....and create a new one. Yes, it's a little work to…

    Sometimes this hobby really makes you want to lose your mind. I had intermittent stuttering. After trying everything I could think of I ultimately deleted the CFG file and then restored all my settings. Now I have very smooth flight. I run a 3840 4k setup. Resolution in CP set to 30. Vsync on with TB and unlimited in the sim. Appears I'm maintaining 30 easily despite some heavy sceneries. I'm noticing particularly in Megascenery earth areas that ground texture is blurry and very slow to load. Any ideas?
