How to Fix MSFS Random Freezing or Crashing on PC?

Now, you know the reasons that cause MSFS freezing in fight issues on your Windows 10/11 PC. This section will help you troubleshoot the problem with a complete list of effective solutions.

Solution 1: Check System Requirements

Before you try any other solutions for the game, all you have to do is to check the system requirements for the Microsoft Flight Simulator game. Ensure your PC meets the below-listed minimum system requirements rather than the recommended ones.

You can check the Microsoft Flight Simulator game system requirement from the Microsoft official website.

Make sure to check the system requirement as per your MSFS version. If your PC does not meet the above-listed requirements, consider upgrading your PC.

Solution 2: Check the Internet Connection

After checking the system requirements of the game, the next thing you have to do is to recheck your internet connection. A slow or poor internet connection stops the game from running properly and results in causing crashing or freezing.

  • Open your browser and navigate to any speed test site. Then, look at the results and ensure that your network is stable and high.
  • If you find the network speed is not as much as expected, consider contacting the Internet Service Provider.
  • Ensure the minimal distance between the router and your computer when using a Wi-Fi connection.
  • Try restarting the router by turning it off and powering it later.
  • Still, if you face the same problem, unplug the power cable from the wall outlet, rest it for 5 to 10 seconds, and power the cables.
  • You can also use an Ethernet connection or a fresh VPN (Virtual Private Network) if you have it.

Now, launch the Microsoft Flight Simulator game and check if the crashing/ freezing issue is fixed now or not.

In case this RAM is filled up, your game will crash or freeze. This issue can be resolved by restarting your PC (this cannot help you all the time), increasing the RAM physically, or by increasing the virtual memory. If you do not prefer to increase your RAM physically, you can increase the virtual memory by following these instructions.

For instance, if you have 8GM RAM, your Initial Size must be 8*1.5*1024= 12288 MB. The factor 1024 in the above calculation converts the GB into MB. And, coming to the Maximum Size, it should be 8*3*1024 = 24,576 MB.
