  2. The latest version of AS is working well with P3DV5. Using EA and Volumetric Clouds and doing some weather feed tests first time I have seen active thunderstorms and lightning generated in one place (KRND). What was impressive was the random nature of the lightning which was not a single type but a variety of shapes and lengths across the field of vision. The cloud texture and colour (from the ground was consistent with real TS weather) the precipitation varied and looked ok too. Still working on some possible changes to the volumetric cloud config to see if that blocky look of cloud below at high altitudes can be improved. Overall AS is working well with EA and Volumetri…

    Very strange, my P3Dv5 reproducibly crashes over a certain point in the Italian Alps, few miles northeast of Bolzano. I see it suddenly stuttering, fps going down from 30+ to 0.5 and a few seconds later CTD. In the event viewer I see it's terrain.dll whcih crashes. I don't have any Addon Airport in the vicinity. ORBX Global and LC Europe is installed. Would very much like to know if that is a problem on my end.

  6. I just did a test flight from KIAH to KMEM, after departing from KIAH everything was sharp and crisp, but the further I got along my route, the ground textures starting getting more and more blurrier. Does anyone know what the cause of this is? I am using ORBX Global, Vector and openLC. Never seen this problem before. I have recently installed a new copy of P3D v4.3 along with most of my addons. I'm not sure if it has to do with the Library Scenery Insertion Point order in FTX Central. I checked it and mine is set to: FTX entries should be inserted below: Prepar3D Scenery openLC entries should be inserted below: FTX Is this correct? I know FTX e…

    I have a mouse with buttons that can be assigned. Long ago I set it up so captain’s vc view could be switched to spot and vice versa. Also, I could cycle through the different vc views, e.g. FO, FE, and back to Captain. Razer ate my file, I guess, and I have been going through P3D commands for hours and can’t figure out how to get it right now! Is there a way to assign a key command to a particular view? I am not interested in any views but these: cycle stations in the vc and back and forth between captain’s vc view and spot. Now, I’m getting all the outside views (tower, etc.) and that “no vc vc” view when cycling same.

  8. Hi, I have tried several ways of improving the ground steering behaviour of the A319/A320 using different settings of null zones and sensitivities for my tiller hardware (an usb wheel, a joystick and also the normal tiller key programmed by FSLabs). Unfortunately nothing is satisfying me. When using the tiller the plane is reacting very late to the input (although the null zones are set to small values and the sensitivity is set to maximum values) and when reacting it is always kind of overshooting. I find this behaviour only with my FSLabs airbusses but not with the PMDG and Qualitywings planes. Was the airbus just programmed this way to simulate a realistic…

    In their support forums MilViz has released v5 installers for several AC. There may be more, but, for me Otter, Turbo Otter, Beaver and PC-6. A reversal from earlier statements about charging and on again / off again. No changes except compatibility. Kudos to them, I have been a critic at times but credit where credit is due and THANKS to the MILVIZ team. Joe

  11. Hello, I have an odd situation going on that I cannot figure out.Using P3Dv 4.5HF3. I fly only the PMDG 737NGXu and 747, with Active Sky P3D ,and Navigraph charts, GSX and Chaseplane, FSUIPC for controls. My rig is AMD 5900X with GTX 3090, 32 GB RAM. So here is the deal. I have smooth performance when I taxi and takeoff and fly. But after I land there are one per second stutters while taxing and turning that ruin the immersion. The stutters occur at standard P3D airports as well as complex airports like FSDT KORD. Nothing I can do seems to resolve this when it occurs. I have tried lowering AA, or even turning it off. Pushing P3D sliders to the left, etc. Exiti…

    Hi, I've recently purchased ProATC after flying RC4 after over a decade 😃 I'll ask here as from my understanding there is no frequent support on the forum, appreciate any help. My main issue is around approach & vectoring- 1. Vectoring is not working well for me, usually after the STAR ends the controller vectors me too late to intercpect the localizer and I get course correction to intercept it from the other direction, is there a way to improve that? 2. Is there a way to request vectors before the STAR ends? 3. Is there a way to request visual approach during the STAR rather then wait until reaching the last STAR waypoint? 4. Airli…

  14. In P3D 5.2 HF1 I found that textures remained blurry at a shorter distance than in previous versions and their loading during flight was slower but I solved it by inserting an old configuration TEXTURE_SIZE_EXP = 10 in Prepar3D.cfg - [TERRAIN]. It should be borne in mind that you need a performing hardware, I have a Gigabyte RTX 3080 Ti 12 GB - RAM 32 GB 4000 Mhz and an SDD M2 Samsung 980 PRO 1T because with TEXTURE_SIZE_EXP = 10 the VRAM increases considerably but the textures they are perfect on any scenario even at considerable distances.

    Am thinking of upgrading to P3d V5, but need some info first. I have 4.5 already. Is v5 a free upgrade? If not, what's the price? Am on a limited budget. How will it affect aircraft already have? PMDG, Aerosoft, Carenado, stuff from Simviation, etc. I really don't want to have to re-purchase or re-download everything? This is my current system : MSI Z390 Gaming Edge, I7 8700 3.2Ghz, EVGA RTX 2060 KO, 32Gb Corsair "Vengeance LPX" 2666, Win10 64. Will this system handle it OK? In general, what kind of framerates or settings can I expect? Any info would be greatly appreciated. Thanx.

    OK so I have a ton of addons in P3DV5.2. Seems now after an initial boot up of my computer it takes my sim about twenty minutes to start from the time the I hit start with administrator. After initial start I can shut down the sim and restart it all day long in about two minutes even if I leave my computer in sleep/hibernate mode and leave it for hours. I've viewed a couple U-TUBE videos on this issue including lining your scenery library properly and taking things unneeded out of the sim object file. These seem to help a little with performance but the initial start up is still long. I've seen past post about this with no real conclusive fix, so I just start my computer…

    Hi Everyone Have recently picked up the PMDG B747 and 8 expansion. My problem is that whenever i depart off RWY 25L i get to the rotate point and the aircraft won't rotate its nose lifts and then slams back down to the ground further attempts see the same thing. Trims are properly set for takeoff, the correct power is being developed. I think its a scenery problem as i have had successful flights elsewhere but always 25L at Anchorage. Given the directions the runways face only 33 and the 25's are real options in big aircraft. Anyone have any ideas?

  21. Hi, Using P3Dv4.5 I was able to get the Avsim Library Avro York up to a reasonable running state a couple of years back. Revisiting the aircraft now I have run itno a problem: the textures are rendered in bmp image format. I am now unable to open these images at all with the various apps and keep getting the message "Error: unable to open this format" or similar. I think this is because the format used is no longer supported under Windows 10 because even Microsoft Photos cannot open these files. Is there a way to convert these bmp images into another, usable, format? I have searched online, but the only app I tried gave the message: "Error encounterd - unable to cont…
