Crashing/CTDs issues

Follow

On occasion, you may experience crashes when launching the sim or during your flight. Below you will find a list of common troubleshooting steps that have been known to reduce or eliminate CTDs entirely.

NOTE: If the crash to the desktop happens while flying in the same zone, at the same location, every time, please file a bug report. Make sure to include the GPS coordinates of the zone & crash. Our QA team will investigate and add the location to the backlog if necessary.

 

 

REMOVE MODS & INSTALL UPDATES (ALL VERSIONS)

Outdated mods or missing Windows and Xbox services can prevent the sim from launching or cause crashes/CTDs.

Before troubleshooting your system or reinstalling the game, we ask you to do this simple test.

 

1. Move ALL add-ons (including liveries) from the Community Folder to another temporary folder (on the desktop for instance)

2. Disable any 3rd party software and programs connected to Microsoft Flight Simulator

3. Install the Windows and Microsoft Store updates (even if you're playing on Steam) 

How to install Windows 10 updates 

Click on Start (the Windows icon in the bottom left-hand side corner of your screen) 
Select Settings
Go to Update & Security
Stay on Windows Update
Click the Check for Updates button.
Wait until the verification is done

How to install Microsoft Store updates

Click on Start screen (the Windows icon in the bottom left-hand side corner of your screen) 
Select Microsoft Store
Click on the Arrow icon or the three-dot menu (top right corner of the screen)
Go to Downloads and updates.
Click Get updates
Select Update all

Note: You can turn on automatic updates to make sure you won't miss future updates.

Select the Start screen, then select Microsoft Store
click on the Arrow icon or the three-dot menu (top right corner of the screen)
Select Settings.
Under App updates, set Update apps automatically to On

4. Relaunch Microsoft Flight Simulator, and try again.

 

Outcome #1 - The sim stopped crashing

  • If the sim stopped crashing when removing Community Created Content and add-ons, move the add-ons one by one in the Community folder, until you identify the conflicting mod
  • Contact the creator of the mod to request an update of the add-on.

 

Outcome #2 - The sim keeps crashing

If the sim keeps crashing, and it's your first time playing, please make sure that your PC meets the minimum requirements.

To see how your PC stacks up against both the minimum and recommended requirements for Microsoft Flight Simulator, including your CPU, video card, RAM, Windows version, and free disk space run a system detection tool such as Can You Run IT.

 

If your system meets the minimum requirements and/or the issue appeared recently, see below for troubleshooting.

 

CONFLICTS (ALL VERSIONS)

Some programs can cause Microsoft Flight Simulator to crash on start-up. To investigate, please do the following:

  • In the Windows Search bar, type "Task Manager
  • Select Open
  • Go to the Start-up tab
  • Disable all non-Microsoft apps
  • Reboot the computer
  • Try launching Microsoft Flight Simulator again

If the sim stops crashing

To find out which application causes the sim to crash on start-up:

  • Enable one non-Microsoft application
  • Reboot the computer
  • Launch Microsoft Flight Simulator
  • Enable a second non-Microsoft application
  • Reboot the computer
  • Launch Microsoft Flight Simulator

Repeat this process until you find the application that is causing the crash. You can then disable this application or stop the process in the task manager before launching Microsoft Flight Simulator.

If you are able to launch the game after doing so, change the game to Windowed mode in the game settings and then reconnect the monitors.

If your system is overclocked:

  1. Disable Intel Speedstep on your Bios overclock menu
  2. Lower or disable your CPU overclock values
  3. Disable GPU overlocking for your Microsoft Flight Simulator game profile on Radeon Software or Nvidia nTune (this applies to custom user overlock settings, not for factory overclock settings of the manufacturer)

 

Please refer to your manufacturer's guidelines regarding how to disable or lower the overclocking speed of your CPU and GPU. 

 

BACKGROUND APPLICATIONS & OVERLAYS (ALL VERSIONS)

Close any unnecessary background applications and disable any overlays while running Microsoft Flight Simulator (Steam, Discord, etc)

 

POWER SUPPLY (ALL VERSIONS)

Power supply problems manifest themselves under load. 

To avoid bottlenecks make sure that your power supply is providing enough power for your whole system while running processor-intensive tasks like playing Microsoft Flight Simulator, not just your GPU.
