    Hello! I have seen other people having this same problem, that the scenery.cfg is capped at 1099 entries. If you add the 1100th entry, then P3D crashes on startup. Is there a reason for that? Could it be removed somehow or in the next hotfix? Best wishes!

  2. Morning fellows. I had a complete HD failure containing all my sims. But I have a great backup system so I am doing a reinstall (that sucks) of the sims. I also have been focusing on XP11 for last year and half. So I am staring though with P3DV4.5+, I do not the hotfix installed yet. I have loaded in all Orbx Global, All Orbx Regions, and about 1/2 of my Orbx airports of which there are some 100+ using Central which works like a charm. I have done no tweaks and I have lost all those wonderful small things that need tweaking here and there but I'll get to that. So please look at this screen shot. Somewhere along the way, perhaps I missed somet…

    I have already posted that I am trying to rebuild my P3DV4.5+ because of a hard drive failure. While thing are going slowing its getting done but I have encountered several issues along the way that I can't recall the solutions. As I fly in hilly or mountainous terrain, my mesh is "popping" into its full extent as I move forward. I am using FreeMeshX. I believe that this issue is caused by not have several layers of mesh at lower LOD such as 7,8,9 and so with LOD 10 (FreeMeshX) the sim compiles the higher resolution mesh as it comes into a certain distance. I believe before I had a bunch of IS this correct and what mesh combo should I have to remove this is…

    Hi Lately I've started using "Little Navmap" because I think its great, but after some other problems I decided to rebuild my PC. The problem now is that GSX doesn't ask how many passengers to load, and it then goes to loads only 1 passenger - and you can tell in flight because of how light the aircraft is. I suppose it's how you create a flight plan in Little Navmap - how do you say there how many passengers there are, but I can't see the setting? I'd really appreciate some advice (it's Aerosoft's A320 Pro that I use, btw). Gaz

    Prepar3d 4.5 is running ok on my system, most settings are high or even max, and I get around 30fps at even busy airports. If I lower any details, frame rate goes up accordingly. But still, I can't help wondering, why both my CPU and my GPU only use around 30% of their maximum. I have an Asus Z87K motherboard, i7-4770K cpu, EVGA RTX2070 XC gpu, and 24GB 2133speed ram. Could it be that the ram is too slow or the cpu throttling back due to temperature - (it does often go into the 80s)? I don't want to spend hours agonizing over it as it runs ok, but just wondered if anyone can suggest any other reason.

  10. Hello! What features would you like to see implemented in Preprar3D v5? For me, I have a few wishes. For one, I wish that you could change the color and transparency of the menu bar in sim. Another thing is that a few default airliners (like the ones from PMDG) in the game by default. Granted, this would raise the cost of the sim, but there should also be an option to buy it with just default planes- no airliners for a cheaper price. And finally, I wish to see backward compatibility with x32 planes in an x64 sim- this would give people that dumped a lot of money into FSX or earlier versions of P3D (before V4) use their planes in a better sim. Now, what would you like to s…

I've been trying to make my P3D more realistic, and have been adding lots of addons (FSGU_NG, ORBX, SF, PTA, ReShade, aircrafts, and so on...) Then, I saw this video below. I'm trying to reproduce it exactly like that. But unfortunately, it's based on URP v1.1 "lightroom.fx", which I just can't find a link do download. Can someone help me?

    Been looking at this add on for a while... https://www.turbulentdesigns.co.uk/product/terraflora/ The tree types look really nice in the screenshots, and the cost seems quite reasonable, but i'm starting to think that if you don't do a lot of relatively "low and slow" VFR type flying, there really isn't a lot of benefit here. Disabling the "speed trees" in v4.5 was the best thing i've done recently to improve the look (and perhaps performance) in P3D, and if using this add on would get rid of the remaining default bright green trees, it might be worth it. I would be interested in hearing opinions on this, thanks.

    Hello experts When loading P3D v4 versions (4.3-4.4-4.5 he stops at 6% during loading terrain dates. The waiting time is almost between 20 -120 sec or in some cases longer. I am supporting other simmers and all of them have the same stops after 6% loading of terrain dates. We always take care not to install addons which are not really approved for P3D v4. But some case we need to install older FSX sceneries but we check them if we can use it. If not, we deinstall such addons. I recognized, that this short loading stop at 6% can also happen on fresh new installed P3D with scenery addons approved for P3D v4. Question: Is it possible that the P3D v4…

  19. Hi All, Recently I've updated from a i5-4590k to the i9-9900k pared with 16gb ddr4 3200mhz . I didn't upgrade the GPU this time around, which is still a GTX1070. So, previously I had a very well ballanced system, but now I have a over the top CPU. While dailing in the P3D config file I'm stuck with a frame drop every other second. It is flyable, yet noticeable. I started observing what actually was happen during these drops. When I looked at the GPU performance tab I noticed that at every drop it showed a small peak in the "copy" graph. I did a search on this, but couldn't find anything. Does anyone know about this behaviour? And more interestingly …

I thought it would be a good idea to have an overview which are currently available, how good they are modeled (quality) and how they perform (impact). It is clear that performance strongly depends on hardware/ P3D settings and other scenery in this area.

    Last night I installed my SSD. I then downloaded P3dv4.5 and tried to install it to my SSD which I have labeled my E/Drive. I pointed the P3d install to the e/drive and commenced the install. It did not install to the SSD but did a sort of repair to the current P3d on C/drive. I now understand that I cannot have 2 versions of P3d on the same drive. So if I were to remove the Client/Content/Scenery installers off my C/drive along with my 3rd Party aircraft. Could I leave my 3rd party scenery files on the c/drive and then map them through the scenery library to the ssd and still get fast loading times. Is there anything on the P3d Forums about this.
