    Merry Christmas all! I found the default turbulence (wind & turbulence effect) settings in Active Sky too aggressive on the aircraft so was looking for recommendations and found people are using the FSLabs recommnedation of 20% (where default is over 70%) and now I encounter no turbulence effects throughout my flights (on any aircraft). What is your recommedation? Do you get turbulence while flying through clouds in EA mode? Thanks. Shomron

    I wasn't going to but I did purchase and install P3DV5.3, I can't even get it to load without a CTD, its a complete vanilla install, no addons at all, nothing, no modifications, no shader apps nothing, it will load to 100% and then it completely disappears, updated nvidia drivers to the latest, no logging of any kind in the event viewer, not able to load anything at all, I just don't understand when you purchase something that has or will give you grief, P3D4.5 runs perfectly with no issues at all, is there a problem running V5 alongside V4.5? uninstalled and reinstall and just the same, loading to 100% and CTD straight away. where the hell would you start to look for an …

  4. Has anyone else experienced stutters in "windowed mode" but smooth as can be in "Full Screen" mode which is actually a borderless window mode? I can toggle the behavior back and forth with great regularity. I'm running with: 497.29 Nvidia drivers and a RTX 2080ti. I run with EA on but no volumetric clouds and use ChasePlane, ASP3D, ASCA and Orbx Global, LC, Regions as well as Orbx and Flightbeam airports. It doesn't seem to matter what is activated or not. Also I have disabled full screen optimizations etc... and run Win 10. I did not experience this with v5.2 it started after the initial update to v5.3 and has held consistant through the la…

    Did a complete reinstall with the hotfix of the 5.3 hotfix last night, downloaded new ActiveSky, switched EA on. I'm getting the strangest cloud 'movement'. It's like they're moving or regenerating in the air. See here: https://imgur.com/Wykx1Ua

  8. There are some good bargains for Christmas, so, if Santa is allowed to fly in this year or you get some change from grandma, I recommend looking at the really cheap P3Dv5 scenery from Sierrasim and Wingsim. I mean, we're talking less than $10 for some decent looking and interesting South American or Caribbean scenery. Maybe Columbia doesn't come to mind for flying, but there are a lot of cheap sceneries that have tons of flavor and some cool approaches. For the price, they're better than most stocking stuffers. Try one out for $6.79 U.S. (I looked up the exchange rate against the Euro; but you better move fast, not only because of the sales, but I'm not confident that's g…

    In previous versions, Shift + Z used to give a different line of info on each press and then combined them to show all. Now it seems that I cannot get just the FPS/GPU info unless I have all the other heading, weather info as well. Any work arounds?

    I have added the IniBuilds dynamic lighting updates to a handful of airports in P3Dv4.5, but the instructions for FlyTampa Corfu are not perfectly clear. The Readme states that I need to disable the following effects in the FlyTampa/Corfu/Effects folder:- flytampa_DynamicFlood_lgkr_white.fx flytampa_DynamicFlood_lgkr_white_small.fx The problem I have with this is that this folder does not exist, and those two files are not in the main Prepar3d v4 Effects folder. I have not tested the upgrade yet, but I just wanted to know if anyone else here uses the IniBuilds dynamic lighting update for FlyTampa Corfu?

Is it worth the cost and effort upgrading to v5? I run Active Sky, Radar Contact, PMDG, A2A and Majestic (Dash 8). Thnx for advices.

    Hi everyone, I have a lot of external scenery and was finding with P3D 5.1 and 5.2, it was taking a long time to get to the loading screen with all of my additional addon.xml files - even when they were disabled. So I moved all of my scenery to the scenery.cfg file and moved things folders like 'Effects' to the core directory which seemed to work fine. Loading times were massively sped up so kept the structure I read a post on LM website that they were looking at speeding this process and was wondering if anyone had noticed loading times increased in 5.3 HF 1? I don't want to move everything back to the addon method if its gunna be a 10 minute load each time vs …

    I've downloaded the new AS version for the 5.3 HF 5.1 with the lights fix. When trying to run ActiveSky I get the following message: We were unable to located requried folders/files. Please browse to your Prepar3D Application Data Location in the next screen. If you are running in a networked configuration, select the proper share. Can someone tell me where this folder is / what I should do next? It was fine on the hotfix, but with the hotfix update and the new version of ActiveSky I get this.

    Hi pilots On the 21st of December there was a sale action from CaptainSim. The homepage was extremely hard to reach. The purchase was an adventure. I bought the 737-300 and the 757. Now I have an activation problem until today. I have deactivated the windows firewall and my activirus program and still both planes cannot be installed. I always get the following message: Error 33: Internal server response error. I have been trying for 3 days without success. Does anyone here the same experience??? P.S I would like to use an Instant Online Activation Regards Julio Garcia

    This recently started happening... I would load into an airport such as IAH shown in the screenshot and my textures would go black. Some terminals and buildings and my entire plane. I would wait 30 seconds, building textures would come back but half of the plane would still be black along with the airport. To fix this i'd go into the display settings and change the textures from high to medium then back to high, that for whatever reason works for me. After a little bit i'd setup the GSX experience get all the boarding done ext. at a nice 30-45fps. After a little bit my fps would just suddenly drop to 15 fps and will not go over 15. I tried repairing the sim, tried to gene…

Effects are always on in add-on airports that have apron effects for example. I'm specifically referring to light effects and during day (did not test other effects), they will stay on. Anybody else have this? Thanks

    Hi guys, I accidentally deleted the add-on.xml file from my p3dv5 folder and I do not have a backup. I have some orbx stuff but also a lot of airports, freeware etc. I haveo idea if my scenery is displayed correctly now but concerning my deleted file I guess it doesn't. How can I get this file back? I wanted to install misty moorings alaska stuff but I screwed up. I noticed that p3d does not create this xml file by itself. The backup version of this file is also gone. How can I recreate this add-on.xml file? Any help would be great! Jozeff
