Some time ago, (many months), there was an issue with AI planes being generated around your aircraft, but as you moved away, they never got deleted, which cased the sim to slow down, and for many CTD.
This got fixed in an update, and the problem then was solved.
But now, since some later update, it seems that AI traffic is not following the General “Traffic” and “DATA” settings, and it is not possible to now turn them off.
With all AI & MP settings to OFF, LNM indicates that there are now still AI traffic being generated in MSFS.
Strange – This happens at KIAD (as above), but not at say KJFK or KMIA.
No addons scenery in Community.
As I fly away from KIAD the planes at KIAD are removed, so its not so bad.
But it might explain the FPS drop @ KIAD.
Maybe its some KIAD scenery in Official ??

YES - KIAD Dulles International Airport by Flightbeans in OFFICIAL
so a bit of a false alarm – except - to show that some of these addons or bespoke airports are adding AI Planes at the airport, that may well be one of the major causes of low FPS at these Airports.
IF that is a FPS issue, I would far prefer the OPTION to have the FPS back, and have no AI planes at the airport.
Hi
I’m running at default levels but I run with Live Traffic on as AI traffic had a lot of CTD issues not sure if this is still the case so might try AI generated traffic again.
I don’t get why the slow down. Aren’t these planes behaving like an object rather than full AI traffic? they are purely aesthetic, like a cone or building. Right?
NO, (I believe) they are actual Planes models that you have as part of your plane collection.
They show as AI traffic in LNM, and have the aircraft types that you have in your plane collection, as called by by model matching to what is specified in the scenery.
The closer you are to the, , the more detailed they get (LOD), and all that has to be rendered and processed by your PC … gobbling up FPS. They are NOT static scenery objects, (like a Plane modeled like a building).
OK, so I do not 100% know all this for sure – its just based on what I have managed to pick up from the forum, and 25+ years of MS Flight simulator usage.
The deeper I did into MSFS 2020, the more confused and disillusioned I get.
Just spent some time digging into the Radio Audio. On the surface its appear to be OK, but as you dig down, its a Pandora’s BOX or unreality.
Lately I set AI Traffic to 85 to fill the skys and MSFS is vey accommodating. However, I’m starting to see an FPS hit with AI Traffic. Sometimes the ATC chatter (approach, departure, and center, not tower or ground) doesn’t let me break in for a long time because ATC is managing a large number of aircraft. As the chatter continues, I notice about a 10+ FPS drop returning to normal when the chatter stops. I am surprised that the processing of AI Traffic chatter steals FPS. When Ai Traffic is disabled, there is no FPS impact. My ATC conversations are short enough that any FPS impact is too small to be noticed. I don’t use Real Time traffic so I have no idea if the Real Traffic audio has the same impact.
I know there are two sources for voices and I switch between them every so often. Text-To-Speech currently is set to “AZURE”. I’m going to try “WINDOWS OFFLINE” to see if it makes any difference.
That would appear to be quite Unrealistic. In real life, controllers do not typically handle so much traffic, that there is difficulty for a a given pilot to communicate when needed.
In crowded situation, there are more controllers, on different frequencies, handing smaller sectors - so defiantly room for improvement here.
However, this could be considered to be a really a LOW Priority at the moment, as so few can turn up AI traffic to any significant level, before their PC comes to a “Chattering” halt.
It probably doesn’t help that apparently the AI aircraft don’t know how to set their altimeters properly, so we get those constant “You are X feet above (or below) your assigned altitude” messages that increases the chatter by a huge amount. I don’t know if that’s an AI traffic issue, or a real world traffic issue or both, as I haven’t bothered analyzing the situation enough, but wherever it’s coming from, it’s a problem.
If the controller has to tell 15 airplanes they’re all off their altitude by the exact same amount before you can get a word in edgewise, that’s no bueno.
I don’t know about AI aircarft, but I can see how some GA Planes can easily be flown at the incorrect altitude, when on AP, in real weather, without the pilot even knowing that this is the case. For instance, in the C172 Classic, the AP is using the Transponder’s Baro, AND the transponder’s baro is also not displaying FL, but instead is being incorrectly adjusted by the B key.
An interesting case of TWO PROGRAMMING ERRORS, being able to can cancel each other out !!
That aside, if the SIM ATC thinks that an AI plane is at the wrong altitude, its the SIM’s fault for putting that plane at the wrong altitude, or it is at fault by believing the p;lane is at teh wrong altitude, Unless it its really trying to “SIMULATE” a sky full of inexperienced, rookie student pilots !!
