That’s why I think it might be Microsoft servers related, that is overwhelmed or executing qos, but only they know if this is being applied.

Just made another flight from Klagenfurt to Turin. Everything was fine all the way, until I decided to divert to another airport (Turin didn’t seem to have any night lighting on its runway). After about one hours flying the frame rate plummeted and never recovered, regardless of what I tried.
I am really at a loss now. When it works, it is amazing, but suddenly it drops off and leaves me with a stuttering mess and I can’t recover regardless of what I try.

I am seriously considering going back to P3D. Even though the weather representation is rubbish, and the graphics aren’t as good, at least I know I can make a flight without it ending in a stuttering mess.

I noticed that in the last dev update it says this is fixed. It is absolutely not fixed. If I leave any traffic settings, boats, cars, fauna on, the manipulators increase during a flight and FPS slowly drops and drops. It is not fixed.

Weird thing is that I had some perfect flights last weekend. No FPS loss. Today I tried again, and it gradually dropped into a slide show. I’m at such a loss

Have you guys ever tried to narrow it down to a certain setting that might let Asobo reproduce before SU11 and hopefully fix. Maybe switch half of the settings drastically to 0 like Fauna etc and see if for a few days the problem goes way. If so switch half of them back to the original setting and repeat to maybe narrow it down to one or a few settings.

I ran the exact same settings 7 days apart (same route - live weather). On one flight I had zero problems, a week later unflyable by the end.
Don’t think it is setting related

Ah right. I was just thinking if some setting meant it didn’t happen for a week (0% reproduction rate) but other settings increased it to, not 100 but even 50% reproduction rate, it might be enough of a clue for the Asobo guys. That would only be as you say, if it’s setting related. Would be a nice find though if you did narrow it down to some settings that increased the chances of hitting the issue.

Yeah, I get this randomly as well. GA or airliner. Very random. I really don’t think it has anything to do with your settings or hardware but something tells me its a mod conflict…overclocking…under voltage…hardware…
Its a terrible guessing game.
I reinstalled a bunch of VC+++ runtime from MS. Maybe that will stop this issues?
Some of them are Net runtime issues as well.

Yeah I did see the overclocking variant of it a while back when overclocking my 5950x. When overclocked just slightly too much, the likes of cinebench would pass a few runs and be super fast, then all of a sudden a run would be ridiculously low in terms of score. Like the cpu is somehow slowing itself down to keep itself operational. I wonder if thats visible in hwinfo or tools like that, probably something like the ‘effective clock’. Itd be interesting to do a screenshot of those tools before and during the issue occurring to see if anything like that stands out.
What I can’t figure is that if I exit the sim and reload straight back in, the performance is back to normal. If it were an OC problem, wouldn’t this show itself again fairly quickly?
Plus, when performance slowly downgrades, all CPU usage values and Temps are no where near the maximum.

At reload maybe MSFS has finished downloading all the scenery and texture files it needs.
Shouldn’t CPU utilization and temperature decrease as performance decreases (depending on the cause of the decrease)?
Hadn’t happened in a while, but just happened tonight. Admittedly, it was a longish flight.
4.5 hours LEPA to BIKF (Iceland).
All fine until on approach then starts to tank again, landed ok (ILS) and taxi / shutdown the aircraft (PMDG 737-800). FPS tanking at the usual 13fps.
Here’s what I tried whilst parked on the ramp (I try one thing, if it has no effect, turn it back on and move on):
PG off - no effect
LOD - lowest setting - gained 2fps
Object Quality to lowest possible - 30fps…
Live traffic off - no effect
TAA / DLSS - no effect, slight better on best performance for DLSS, put it back to TAA
Quit to menu, did NOT leave the sim, back in at the same gate and airport (BIKF) - 40fps on max everything.
There is very little in the way of buildings etc at that airport, also the sat imagery is not the same level of detail as other places. I personally think it would tank 13 fps in the middle of Greenland in this scenario, I just don’t know what causes it.

When my FPS tanks, GPU Util drops massively, CPU drops and the temps drop, so much so I can actually spin up another game in Steam and play that at the sametime MSFS is tanking FPS…

After trying with multiple planes, using the memory leak trick from ms2000 flight simmers (youtube) and it still happens. I can’t even fly more than 1.5 hours before my FPS tanks.
Oh, and it has Absolutely nothing to do with any settings. Nvidia, Overclock, no overlock, community folder emptied.
This bug is Asobo, pure and simple.
Makes the sim unplayable when your expensive rig loses all FPS for no reason.

It is traffic, ground vehicles, airport vehicles, boats, fauna etc, turn them off you won’t get fps drop.

With all due respect I have to disagree here. I have turned all of these off completely with no traffic of any kind and it still happens.

I had a roughly 1 hour 40 flight out in PNG earlier, no slow downs or frame drops.
It’s a bug that is highly situational. What plane were you flying when you last had it?
I’m currently flying default Cessna Longitudinal from LSGG to EGLF. Cruising at FL450. Have turned off all AI aircraft.
Just approaching north coast of France when my fps suddenly dropped from 66 to 11, just within seconds.
Now down to 9 fps
Sigh.

I would love to see a report from a 6-8 hour Cessna 172 flight, but no one ever has, and my suspicion is it won’t affect that plane.
The argument given might be its far too slow to do those flights, but I would counter that with the destination being irrelevant. All that is likely relevant is the duration of the flight, so if that 6-8 hours amounts to only a tiny fraction of the overall flight, the test is still valid.
If no one else feels up to it, I may do it myself, and hopefully put this to bed once and for all. I would probably kick it off on a a Friday night, and pick up on it on the Saturday morning. 172, with unlimited fuel, then just leave it running. Just in case having the dev mode open for long periods of time is a factor, I would open it at the start when at cruise altitude, then turn it off, re-opening it when I check back in.
If the FPS remains unaffected, then I would have to conclude what I have suspected all along, and that this problem only affects certainty types of planes, or perhaps more accurately planes with certain systems/avionics.
I would invite anyone else to run their own tests, excluding the Cessna Longitudes. This should be a prop only, GA test. But I have effectively already done this, as one of the single longest flights I ever did, was in a 172 when I visited every airstrip in Lesotho, which was just over 6 hours of hand flying. Way more than I usually do, but no slow down. Another flight, closer to 5 hours in the JF Arrow, was East into China, and again no slowdowns.
