If all else fails (last resort) do a 'cloud' reset of your PC.
Reinstall P3D and all your add-ons.
I started from a clean install of Windows 10 2004 + latest Nvidia drivers + P3d v5 HF2 and haven't had a single problem in over 2 weeks.

Disabling hyper threading in the BIOS fixed this for me.

This is a Windows 10 "feature".
If a process is running when you shut down, Windows starts it automatically.
Solution is to wait a while after closing P3D before shutting down.

Great news!
Happy flying....

Hi John,

You are correct Jorgen - only the full installer file needs to be extracted:

Do not extract any of the CAB files! The installer program will do that automatically :-)

Hi Jayteeaitch,

I don't work for Lockheed Martin but I will try to help :-)

May I ask which program you are using to unzip the download file?

I tend to use 7-Zip (www.7-zip.org) as I have experienced checksum errors when using the built-in Windows zip facility.

Cheers,

Dave.

Hi Snowfalcon, I use a program called Pro-ATC/X which reads weather from Active Sky (other weather products are supported). Pro-ATC/X clearance delivery will calculate the appropriate runways, SIDs and STARs based on the weather. Unfortunately, P3D default traffic is not so reliable and I often find...

Hi Reza,

P3D is based on the FSX database so these airports are probably not included.
You would need to install a 3rd party scenery.
I was very disappointed when I found this out.
And most of the missions are missing.
And no airliners...

Dave.

I don't work for Lockheed Martin, but most companies tend not to discuss internal strategy with random internet strangers.
In the meantime, I'm enjoying Prepar3D - live in the moment I say...

All the best!

Hi, Please could LM consider an auto configuration module in P3D. It would detect the platform hardware (CPU, RAM, GPU etc) and software (Add-ons etc) and automatically work out the optimum settings. The module would then suggest a configuration profile to apply from a number of pre-set configuratio...

What are the serious performance & stability issues?
4.5 is running great for me, if anything I'm getting better performance.

Dave.

Active Sky can generate an ATIS broadcast. Is it maybe coming from there?
