    In the last month have I had some problems with autogen vegetation. My default startup situation in P3d v4.3 is at my home airport which is surrounded by trees. When I start the sim, most times the nearby trees are missing, but the trees further away are loaded. When I saved the startup situation the trees were loaded. If i go to Options and change the autogen setting either up or down, the trees are loaded. Can anyone give me some advice on how to fix this so the trees load when I start the sim? Tor Arild

    1. When I use the GTN 750 on compatible default P3D aircraft- it appears as a Pop-Up, but often disappears from the screen. I have to reopen the pop up. Is there a way to keep it on the screen or Toggle it off/on? 2. On a couple of aircraft where there is a space for the GTN 750- it covers other instruments (like the autopilot). Can the GTN be resized? Thanks!

    Right now I'm contemplating to finally step up my sim, can't do it with my present computer and I'm planning on building one myself. I know that the CPU and Video card are going to be the most important items. I would like to stay around the $2500.00 budget but these two items can kill this target. Can anyone give me some ideas in term of video cards, CPU and perhaps motherboard?

    Yesterday night I wanted to make a flight from EGKK to KSEA with Norwegian B789. I had the latest update applied via their updater "version to version". Did not make a full install, maybe a good idea? But I had many problems in the flight, and after around 4hrs the sim crashed. So I had no intention to once again restart everything. My problems where the following: performance is changing, even with a GTX 980 TI and refresh rate set so 11 by default I always have more or less good frames airport charts on ND display are not present since the first update.

    Hey all, Just a heads up that v1.1 of the CS757 III for P3Dv4 was just released! I personally have been wanting to get this addon for a while now, primarily to use it as my freighter of choice with FSDT's KMEM and KSDF sceneries. While I know that the freighter expansion hasn't been released yet, I'd be quite interested in getting the base 752 now - depending on how good the plane is now that v1.1 was released. And so, I was hoping some of you that already have this plane could shed some light on how good the addon is, now that it was updated to v1.1? I'm really not looking for a PMDG-type plane, but I do want the functions that were modeled to work properly. Ov…

  11. Hi, Over the last few months I've been playing around with different textures from the major developers including Rex Texture Direct Enhanced, Rex SkyForce, ASCA, Rex Worldwide Airports HD, PTA and also EnvTex a few months back. I want to totally reset myself back to the default textures for the ground, sky, water, runways, etc etc that ship with P3DV4 without doing a full uninstall and reinstall due to all the add ons I have. Would appreciate help with the following questions? 1. Is it safe to uninstall the content.msi and then reinstall it without affecting my add-ons (besides that ones that effect textures of course). I believe content.msi contains the d…

    Hi all- Where are the 750's flight plans saved to disk after saving them in the GTN itself? I ran a *.gfp disk search and could not find a location for a plan I saved, and that still exists in the GTN. I found some other unrelated plans in several places but not the one described above. Thanks, Mark

I believe one night after couple post work sodas (wink) i found a program that i was able to turn off sceneries and since most of my flights are on east coast and Caribbean i thought hey lets save resources and not load half of the scenery i have.

I use Simstarter and also use AddonOrganizer but cant figure out which one gave me the option. any thoughts would be great ie... the problem i'm ha…

    Hello, I have an issue with EZCA v2.0.2.25 and P3D v.4.3.29.25520. About 5% of the time, these two work correctly. EZCA connects properly within a few seconds of loading the plane in, and everything functions correctly. 95% of the time, however, the EZCA software takes at least 5 minutes to load, and when it does, it says "waiting for fs connection" I have tried changing the simconnect version several times, and rarely it fixes the issue. The next time I open P3D it doesn't work again. This is a very annoying issue, and I have no clue how to fix it. Help would be greatly appreciated.

    Hi all, I've been researching this issue for a while now and haven't been able to find a fix. Whenever the engines are on, is any aircraft, default or payware, the is a slight, sutter/vibration/shake that is most noticable when looking at the scenery and it looks horrible. Has a resolution for this issue been found or just a known bug? Thanks in advance. Kind regards

    The performance of DL/SSAA is absolutely better on my system. I made a full uninstall-reinstall which took me half a day to have all my add-ons in place again. Not too bad, isn't it? Then I tested my PMDG 747 at FB KSFO (and FTX SCA) and FT YSSY (and FTX AUS). Frames were set to unlimited. With HDR on, 4xSSAA (!), 8xAF and moderate settings (adapted for night where you need no cloud shadows etc. ...) and with UTL active, I could reach 23 fps at KSFO (28R) and 20 fps at YSSY (34L) - Nearly stutter free and no shimmering ... IMO, it is a big step forward, compared to my former install (4.2) where I only could get 12-15 fps with comparable settings.

    Greetings, I'm looking for a detailed description of the P3D graphics settings for the various components (i.e. FXAA, MSAA, Texture Filtering, etc.). Noted are the descriptions in AVSIM Prepare 3D Guide, pg. 21, figure 11, but I'm looking for a bit more detail in descriptions. Pardon me in advance if there is more detail elsewhere in the guide that I may have overlooked. By the way, the purpose is to solve an issue with the A2A V35 and occasional flickering gauge lights. P3Dv4.3, Win 10/64. Many thanks.
