    Hi all, Sorry for the spam! Is there any way to adjust wave size in P3D v5? In v4 you could use PTA. They look very large from cruise altitude in an airliner. Cheers, Rudy

    Hello all. I have a huge problem here with this add on. I have downloaded this programme many times through the Purchase Agent, and every time I do so, I follow up with a download of the Garmin GTN trainers. After set up and install, when I load A P3D, GTN equipped aircraft I get, firstly, a box telling me that "Cannot find MSVCR120.dll. Please reinstall this application The box is labelled Themida" This does not tell me which programme needs to be reinstalled, but I have read that if it is indeed, Themida, it is not really a great programme to have on ones system. If it is Themida, which programme is installing it (unbeknownst to me) ie Flight1 or Garmin and w…

Neither of these or others are working since installing the Saitek Drivers. There were other issues also but seem to have resolved most. This Yoke System has the Leo Bodnar mod installed .

  5. I noticed that the main thread in Prepar3D runs on core0 and the main thread is MSFS in my case runs on core9. Which is better? I say core9 is better. Reason being is that core9 is the coolest core in the stack because its at the top and therefore has better cooling because its nearest to the CPU cooler. Whereas Core0 has the worst cooling because it is the at the bottom of the stack and therefore furthest away from the CPU. In my OCCT tests core0 on my i9 10900k can reach temps 20c hotter than core9. Why doesn't LM change the code so that the main thread runs on the CPU nearest to the cooler?

    Greetings all.. With P3D V4, does anyone else have the issue when connecting autopilot (APR) to ILS the heading is enabled and works but the glide slope does not sync up? To to be clear I fully understand how to use ILS /NAV Frq with AutoPilot (ie speed requirements ect). My issue is in APR the glide slope bug comes down to flight level but the autopilot never.. NEVER kicks in and I always have to use elevator control to follow glide slope in. I've tested with almost all P3D v4 aircraft and they all exhibit the same behavior. Again anyone else have this issue and know a solution? Thanks in advance, D-Man Seattle Wa.

  7. Could you VR guys (not just WMR but Oculus, Pimax, and Vive +...) comment on whether you have too much (whatever that really is??) stutter with P3Dv5? I only have WMR (HP Reverb) to test with and I have compared plots using frametime data (from FRAPS ) for each frame (not averages) including P3Dv4.5 data as well as a flight sim other than Prepar3D. See the thread: https://prepar3d.com/forum/viewtopic.php?f=6312&t=138375&sid=628b5ab6a37e45c0a0053e5f4c24f2cf It appears that with single-pass and WMR (P3D Version 5HF1), that looking out the side at scenery while flying low (~1000 feet ) suffers from considerable stutter - meaning that even with a constant f…

    Hi guys, These days I am flying mostly in Europe, based in Vienna with the MD-80. However, the regular flights are becoming boring, and it would be nice to hear about any interesting/scenic airports where you can land with tubeliners around the world in P3D. MSFS does better in this area, but sadly not developed yet for proper airliner flying. Most of the scenic places I have found in Europe are mostly for smaller aircraft (apart from Innsbruck). Any suggestions of great places to fly? Can be mountainous, tropical, anything around the world, with add-on scenery for the airport available for P3D V5. It was great in the FS9/FSX days as there were lots …

  11. Hi all, I was looking at this thread trying to get rid of my wings being visible on a moonless night. Whilst I can get them darker, I cannot get them to go black/pretty much invisible like in P3D v4. Has anyone got any advice on making the nights actually pitch black when there is no moon with regard to P3D 5.2 HF1. Any additional bits of shaders I need to modify? I have tried with envshade and with stock shaders, but cannot seem to get what I want - that is a black night where you can't see the wings of the aircraft at night on a moonless night. Also runway is slightly lit up by a non-existent moon. Please help me! I hate bright nights! PS I am n…

I am also thinking about downloading the free TopoSim 20 metre mesh for the islands, so it would be useful to know if there are any airport elevation issues when using this mesh.

    I have a really nice computer, one that can run P3Dv5 pretty much perfectly. My only issue is at some airports, whenever the dynamic lights come on, it's a stutter show and sometimes just crashes my computer all together. Other airports with dynamic lights are just fine, with hardly any loss of frames or performance. Like I can go to FLy Tampa KLAS and have zero loss of performance, but if I go to PACSIM KRNO, it's terrible and causes a computer crash. I usually run using 4XSSAA, but when I fly at night, I back that down to 2XSSAA. Any suggestions, other than not flying at these trouble airports at night.

    In case you guys have missed it. Basically instead of updating the position of aircraft every 5 seconds, the new vatsim velocity will update user positions 5 times a second. The result will be much smoother when observing traffic. Botched landings will now be much more obvious!

    Is there much merit in these continual P3D updates?

    I have a RTX 2080 and would like some input on how my VRAM is being allocated. I know that windows 10 reserves a good-sized chunk for itself but when running P3D, it shows an available VRAM of between 6.1 and 7.1GB of 8GB available. The average available is between 6.5 and 6.7GB. So, some examples: Sitting in the Cargo stand at PANC with Active Sky, AIG Traffic, Aerosoft PANC, and Orbx Southern Alaska I show 7.1GB available in the VC and it drops to 6.5GB external views. The aircraft I'm using doesn't make any difference. Execpt that I run out of VRAM in the exrternal views with the CS 767 (glad I bought it during the $9.99 sale) At FSdreamteam KORD with all …

Anyone knows of any other water textures for version five?
