    Does anyone here have the Scotflight Almond Valley Viaduct model for P3D that was released a few years ago? This was offered as a separate download on the Scotflight forum, but the link no longer appears to work. This is the railway viaduct that is located short of the runway 06 threshold at Edinburgh airport.

  2. I'm getting ready to reformat and rebuild my computer. I'll be adding an RTX 3090 at 2 x 2 TB m.2 NVME hard drives. So while not completely new, it's going to count as a new computer. My P3D install is about 350 GB and I have about 100 add-on files, plus a bunch of Orbx stuff. Unfortunately a decent amount of this install dates back to before Orbx was using an outside installation folder, and a lot of the other add-ons are hit or miss. So any advice on making this as smooth as possible? I suspect I'm going to be reinstalling a lot the hard way, but figured it can't hurt to check. And any advice on moving controller configurations? I use FSUIPC and LINDA, …

    About a year ago, I read something on this forum regarding ORBX VECTOR. It seems that there were many who said it is not really necessary and it impacted their framerate excessively, and caused pauses and stutters when flying. SO, I removed it. I have been very happy with P3d ever since. Flights are smooth, relatively stutter free and everything works great. My question is this: What am I missing? I recently noticed a geographically familiar airport to me was missing so much real detail, and the topography around looked really weird, with sinkholes and elevations that do not exist in real life. In addition to VECTOR, I also have Open LC North America, Europe an…

    So, is anyone aware if this works in V5. Really missing the 747. I, however, have made a decision to use my $99 NGu credit with PMDG in MSFS and then part ways with them. Not that their product isn't amazing but rather I find the CEO, staff and Minions to be condescending and they have some serious issues with promises not delivered and poor workflow management. But I digress. Ifly 747 in P3D V5? Anyone? Bueller?

    Just curious if anyone has tried it and/or if it has any impact with the 4 series cards from Nvidia. While I am excited for the gains it will bring in the other platform I am also still regularly in P3D in the 777/787 so also wondering if it will help P3D. If not, anyone have any general feedback with the 4090 in P3D in general? I know a few others have them so just curious. This is specific to P3D hence posting it here so hoping it doesn't get moved...

  15. I'm playing around with P3Dv5 at the moment and the Volumetric Clouds. I'd like them, better than the REX 2D Models. But I'm struggling with the AS settings. They have introduced an option for PREVENT ASP3D EA VOLUMETRIC CLOUD CONTROL and an option for ENABLE DETAILED EA CLOUDS. The only thing I'll read here is that it seems everybody is using Active Sky or Rex Clouds and not the volumetric ones. Maybe anyone has the perfect idea or setting? Regards Urmel

    Hi. So basically let's say I have TSS A320 IAE sound package. I want another flap sound. I always get the substitute WAV file I need, I either rename it or amend the sound.cfg file. But there are some files, that P3D just does not reproduce. I took the flap sound from a freeware package, but the sim just doesn't read it, it's quite. The volume is set ok in sound.cfg. Any ideas?

    Hi there, In the P3D.cfg there is a new section added with 5.3, However when it is there i seem to have horrible stuttering when airborne ( FSLabs ) The entry is: [JOBSCHEDULER] P3DCoreAffinityMask=xxxx MainThreadScheduler=x RenderThreadScheduler=x FrameWorkerThreadScheduler=x I don't get any of these issues if i move this section. I assume its been added to help with things. Does anyone have any idea why i get the stuttering when its in the cfg file.

  22. This morning I was flying the Xtreme Prototypes Lear 25 from Prague to Berlin. I use ChasePlane and have various views configured which include two from the passenger seats just forward of the wings looking left and right. Whilst the pilot and other cockpit views easily maintained 30fps that dropped to 15 when viewing those two pax views. That was in full-screen mode. Switching to Windowed and the problem disappeared and 30fps was constant. I've been flying this plane for ages and this was a new problem. What had changed to cause it? And why only in full-screen view? The answer is Triple Buffering. I had turned it off a couple of weeks ago following a discu…
