P3D NT.dll crash

[FSXCYYZEGLL]

Hi all.

I'm currently having an issue at busy European airports (Heathrow and Paris being the one's I've seen this in thus far). Namely there will be a sudden CTD. Each time it generally has this error log or some variation therein.

I use AIG traffic, PMDG 777, and AI Companion. I'm not strictly sure where to go with this. Previous pages on the forums relate to P3D V3 and one fix is to use it in compatibility mode for windows 8, but I don't know if that will lead to performance loss, which is an issue I've been dealing on and off with for a bit.

Are you overclocking your CPU or GPU, or both?

[FSXCYYZEGLL]

Nope no overclocking either the GPU or CPU.

Well tested it in compatibility mode and the performance tanked terribly, so that old solution is out. Not terribly surprising given that V5 is recommended for windows 10 minimum.

Has this problem started suddenly or been happening for a while?

I'd start by lowering your settings. Have a read of this topic.

Don't run Delete Generated Files. That's the nuclear option.

When you get to the create flight screen go into addon scenery and remove the X form the addon`s you mention, use a default aircraft and test. if the this stops the CTD add them back one at a time to try and track to the problem.

PS GPU drivers no longer support windows 7/8/8.1.

It's been happening on and off for a while, though only at Heathrow and Paris as of the moment as far as I can tell.

I'm not sure which settings to lower tbh, when landing and approaching the airport I get a 30 FPS on the approach with relatively few stutters. So if it was a performance issue, wouldn't I see something there?

Also yet another crash in Heathrow doing the 6pm back to Toronto. This time however it came with this error log, a G3d.dll crash with a 0005 exception.

I also tried content error logging by P3D but it didn't catch anything of note and ended at entry 999.

London and Paris, this sounds like AI related, cause if you approach these, the sim is loading AI and one of it maybe damaged.

• So disable AI to test.
• Remember what you added recently. This can help you finding the faulty file.
• If you have AIG run the installer and run the fixing functions.

I agree with Dan. Set Ai sliders to zero and close AIG Traffic Controller.

Do a few flights into both airports. If no problems then definitely Ai related. Use AiCompanion - BGL Report to check for errors.

[FSXCYYZEGLL]

Yeah seems like an AI issue. Did a BGL report, and there were a LOT of issues. Including missing repaints and models for numerous BGL's.

However when I use AIG OCI and click fix repaints or update models, it scans for a bit, then does nothing. So I'm not quite sure what's going on there or how I'm going to fix this.

Jon,

The solution isn’t difficult. First get AIFP3 from here.

Install it to C:\AIFP3. You need to point it to your P3D folder. Once installed come back and I’ll talk you through the steps to fix those problems. If you can provide a screenshot of the BGL Report that would help.

There’s a progress bar at bottom right in AI Manager you may have missed.

[FSXCYYZEGLL]

Hi Ray.

It's already installed and I'll get you that screenshot probably tomorrow, or I can print it off into a pdf right?

I saw the progress bar, the blue completes and then just stays there.

Jon,

I wrote a detailed post on how to cleanup the Ai in this post. I think it will help your situation too.

If you have an account with one of these they are suitable for hosting images…

Images must be hosted on your own image server site, such as Drop Box, Google Drive, Photobucket.com, OZx Image Hosting, or a website that you own.

Don't overlook Steam as a pic repository, Steam does provide acounts 20 GB of on-line storage for screen grabs and artwork.

If you had FSX-SE or any other steam game then your Steam account is ready and awaiting screen grab uploads.

You just need to add your fav flight sim to Steam as a non-steam game, then use a tool like SteaScree to prep the screen grabs where they can be uploaded via the standard Steam UI.

It's a pretty simple process.

Cheers

Ray that seems extremely helpful. Thank you.

Also I was worried that my crashes may have been due to another program like AI flow. But I tried again and it literally crashed before I even opened it with a NTDLL. Then afterwards I reinstalled the graphics driver (cause why not, plus I was seeing some graphics driver related issues like audio freezing). and tried it again, another crash with NTDLL. So I agree with you that it's almost certainly related to errors in the AI.

One thing, I've been doing what you recommend, and for some of the aircraft I'm getting no paint errors and replacing those, but other aircraft are in red in AIFP3 for some reason despite BGL report not stating there's an issue with them(I can also view the models in BGL report). I'll be honest I've never seen those aircraft in the sim anyways, but the model file is still there, just AIFP can't open the model for some reason and has the aircraft in red. Some examples include the Bombardier Global express.

I guess my worry is that if I don't replace all aircraft showing red in AIFP3 that the crashes will stay, but since it won't show a bug report on BGL report it'll be impossible to find.

Jon.
