Brief description of the issue:

My computer parameters: i7-12700f + RTX3070, 32GB-DDR4 3200 RAM,2T SSD,2560x1440 165Hz display.

When I set the departure and destination airports, I will get very low framerate after takeoff.

If I only set the departure airport and not the destination airport, then everything works fine for my FPS.

If a bigger plane is used then the FPS will be lower.

If no destination airport is set:

Of course, if I stay on the ground, the frame rate is normal:

Detailed steps to reproduce the issue encountered:

1. Arbitrarily set the departure airport and landing airport to start a flight
   

   

2. Good FPS when on the ground:
   

   

3. Take off, leave the airport, the frame rate will drop instantly:
   

   

4. Restart a flight, only set the departure airport, do not set the target airport, take off, the frame rate will behave normally:
   

   

PC specs and/or peripheral set up if relevant:
Default Ultra Graphics Settings.

Build Version # when you first started experiencing this issue:

Ultra Graphics Settings

That’s usually the problem.

Please read in full, when I don’t set the landing airport, I get normal FPS.

If you’re flying the same route twice then the cache data could be improving your performance the second time.

Added: Dropped frames are persistent, I will get 10fps forever.

My hardware usage is usually low when persistent dropped frames occur:

No, I’ve changed planes dozens of times to do this test, and it’s only when the landing airport is set that I consistently get very, very low frame rates.

Nasty FPS drop and lagging on take-off and landing

This was the fix I tried at the suggestion of Captain Sasso. Before launching the sim, navigate to Users>YourUserName>AppData>Local>FlightSimulator. There you should find a folder called “mapscache” and a file called “overrides.json”. Make a backup copy of these files, just in case. Delete these files. Launch the sim. I checked and found the sim had re-created new versions of the deleted files Check that Photogrammetry is switched ON. Choose your favourite plane and your favourite airport. Tak…

Thanks, i will try it

That’s no fun if the cache makes your performance worse.

It doesn’t work.

Enable developer mode and the fps graph. Make new screenshots. In the meantime I will see what happens on my PC between those two airports.

Detailed steps to reproduce the issue encountered:

I followed those steps using same airports, same runways, same plane, with no issue. I have graphics on mostly ultra except photogrammetry and live traffic is disabled.

Manipulators may include such items as:

• systems
• planes
• ai traffic
• live traffic
• stuff on ground, world
• weather
• simulation
• (not rendering)
• animations
• cockpits

[xkeyC]

I reset all settings except the control options and the problem persists.

I don’t know what happened.

Sorry I forgot to mention it, I have removed all addons (A plane) when I found this problem.

As you can see,the problem remains.

[xkeyC]

Tested the minimum picture quality, I got amazing FPS before takeoff, only 30 after takeoff.

When no landing airport is set, I get fantastic FPS.

So, what exactly is broken?

I’m using the Simplified Chinese version of Windows, and when I turn on “Beta: Use Unicode UTF-8 in worldwide languages”, everything goes back to normal.
