Performance drop 15-20% after World Update 3 (

Excellent initiative from “Unreality145”, it just got my vote!

Well… I tried the set settings to ultra then set to my desired configuration and unfortunately no luck…

What I did find is that my CPU usage was at 100%.

I’d like to try this but I can’t get access to the Windows/Apps folder to get to the .exe. Appears to be owned by TrustedInstaller and it sounds like changing ownership can cause things in this folder to quit working. How can I get to the .exe to make these changes?

Wow!..what a difference. This was a big help. While I was pretty close to some of these settings, what smoother performance these tips gave.
Thanks much! :100: :+1: :+1: :slightly_smiling_face:


Great. Glad to see it helped!

I did notice a post where someone took possession of the “Windowsapp” folder and it caused all kinds of problems with loading of programs and other things. I did not opt to do that. Still was good!

It’s also possible to access the FS folder without taking ownership of the entire WindowsApps folder. You just have to know the full path. That’s how I do it:

  • start a command prompt as administrator
  • cd \program files\windowsapps
  • dir *flight*
  • copy the folder name (in my case Microsoft.FlightSimulator_1.14.5.0_x64__8wekyb3d8bbwe)
  • in explorer enter c:\program files\windowsapps\ + paste the folder name
  • Now you can disable the full-screen optimizations in “Change settings for all users”

This seems a better way than messing with folder ownerships.

I did this after most updates, but I’m not really sure if it made a difference


Ok…so I take a short flight with the King air from KPVD to KBOS. Everything going fine, high settings like usual. 15 minute flight. Multiplayer, real weather, name tags all on with no issues all night. Start to see a little glitch, hear snapping with ATC talking heading into and getting near Boston. I quickly go into settings and turn off Photogrammetry and go back to flying. All went away. Landed with no other occurrences.

Thanks for that info it really helped as once I disabled full screen optimizations it improved my fps and smoothness when not in one of the 1/2 normal fps, or 2-10 fps areas!

While today’s patch restored performance lost with SU3, I’m still suffering from the perfomance issues that came along with WU3.


With as much as problems have been reported prior to the patch, I will say that the latest patch appears to have solved the manipulators issue I was seeing.

Same exact spawn in location at KMEM, same plane, same mods, now getting 50+ FPS vs teens last night. I even increased resolution scaling to 110% (running 3440x1440 with a 3090 FE) and still in the high 40s-50. Constantly GPU limited.

Semi-concerned this is the first time I’m hearing my GPU fan fire up. Seeing up to 75C GPU temp and max 104 GPU mem temp, need to see if there are concerns there. Of course, just in time for the 70+ weather to start rolling in.

EZEd1063 I have a 3090 and see my temps up in the 70s depending. If OC’d oh yes, I’ve hit 74 celcius. Mine usually runs around 64 degrees with 130% resolution scale 3440x1440. Everything ultra except shadows, it will take it but heat rises more. If I got to 150% scaling I can hit 70 degrees with no OC. The Vram temp does seema little high though. try it with your case open. Might have a ventilation issue

We now have an issue after this latest patch of CTD’s while in the flight planner
Was setting up flight plans and have dropped to desktop twice

Happiness is back. :star_struck: With the latest update and choosing the proper settings, the game runs smooth over London and KATL.

With the recent release of patch, I am closing this thread.
