I disable Steam, VGA and Xbox Game bar overlay and my game is stopping lagging and audio crackling. FPS returned to normal. Big hug guys, i hope to helped!
When this happens (Stuttering audio and bad FPS) i just save the flight and reload the sim. Saving works great now.
Hopefully they will fix these performance issues anytime soon.
My experience, as previously posted, has been slightly different in that FSP would crash sometimes only minutes into a flight. After the Update 9 patch yesterday, I did a flight with abysmal results. So feeling disheartened, I installed the latest nVidia drivers, rebooted, and viola!, no more drops. Iām 8 hours into a 9 hour transatlantic flight with no drops. Fingers crossed this keeps up.
Sorry, We had an Update 9 patch yesterday?
For me itās the VFR map.
Iām currently flying the FBW A320 and after 2 hours the FPS dropped from 30fps to 5-6. I closed the VFR map and the fps immediately jumped back to 30fps.
I donāt know when the performance issues started. I flew the TBM with the WT mod for 5-6 hours straight a month ago and the fps was okay. Though I suppose the WT mod uses a custom map. I flew the A320 for the first time in 6 months just yesterday. I havenāt really flown with the VFR map on for a long time in a year. So I guess that the issue was introduced in the last year.
Im right now in my second flight in a row without leaving the Cockpit. FBW
So far no drop at all
Pc is still on and MSFS still running. Airbus parked at the Gate. Guess i will make a third flight shortly. All in all the Sim is running at least for 8 hours. No degradation at all.
Didnāt make a Flightplan,only departure for the first flight. The sync from the FBW MCDU seems to work flawlesly. Also ingame ATC was spot on for the 2 flights
After almost 2 years of this simulator we still have the same problem. incredible.
I am finishinig a flight with 7 fps.
can i say shame? can i?
Made my 1st PMDG 737 Flight.
I had to save and restart the sim Mid-Flight
Then the Perf degraded again when on Final
Asobo, Fix Your Sim!!!
Dear, I managed to solve it by following step by step what this page indicates. The only thing I omitted is the bandwidth and the settings inside the simulator. I just finished a 3 hour flight and the fps never dropped

will try it tomorrow and report here 
thx
For me, I get a normal 30 fps in the menus, but as soon as I get into the sim, I drop down to ten. I have an i7 1700f, 16gb of ram and a 3060 ti.
This may help some of you guys

you mention this already..
Yesā¦ it definitely has something to do with live weather, especially when itās very cloudy. If you turn it off, the situation improves a lot, even more if you choose a completely sunny atmosphere.
Besides, when Iām taxing I can only see the closest part of the runway with a good definition. Everything beyond seems to be blurry and it only becomes crystal clear as I approach that area.
And I donāt know why, but the simulator has closed and sent me back to the desktop three times today, when it never did it before! This works worse and worse every day, I have paid a lot of money and now I feel totally scammed!!
in flight now after 1h, performances are degradingā¦ 
Hi all,
My first time here, not sure how to make a post.. but i found a reply button to this thread which is very apt.
I hope to be able to help many others that experience an issue, i experienced today (13/5/22).
This is related to Windows 11 update [May 10, 2022āKB5013943 (OS Build 22000.675)
This update totally broke MSFS in that it cause my gpu to power spike every 3 seconds causing massive lockups even in the menu.
I rolled back this update (instructions can be found how to do this when you search for the above update).
Please if this is a repeat post or in wrong place, then point me in correct direction, i just wanted to share a problem i eventually figured out,
Fly Safe!
I had massive performance loss in the pmdg after a 6hr flight. I didnāt have that in the default 747 after I applied the fix that is mentioned earlier in this thread.
I also did a 5hr flight today in the pmdg and that went alright
After many months, I went back to fs2020 to try pmdgās 737, I ran into the same performance drop issue, so Iāll go back to my xplane 11, and wait for 12, I already gave this game many chances, however Asobo keeps putting unnecessary world updates for different countries, without fixing the existing problems in this game, the sim was supposed to have a great future, but with Asoboās decisions it will die slowly and be forgotten
I still donāt know why Microsoft trusted Asobo, a company whose experience is questionable, for such an important project. Asobo has never produced anything which is worth playing, at least according to me. They should have entrusted this project to a real and reliable AAA game producer.
