Microsoft and Asobo Studios released the hefty Microsoft Flight Simulator: 40th Anniversary Edition Update a few days ago. Aside from new aircraft, this patch also adds new features, including support for AMD FSR 2 technology and the memory defragmentation system.

PC players using a compatible graphics card can now enable the AMD FidelityFX Super Resolution 2.0 or AMD FSR 2 graphics option in the settings. This feature helps boost frame rates and deliver better than native image quality, though mileage may vary depending on the player’s system.

To add to that, the game now supports DLSS 3 and NVIDIA Reflex as well. It’s important to keep in mind that DLSS 3 can only be fully utilized when one uses an NVIDIA RTX 4000 series graphics card.

In addition, Microsoft Flight Simulator now uses a new memory defragmentation system for DirectX 12, putting a limit on maxed-out VRAM. This may help prevent the game from crashing caused by an overloaded VRAM.


  • New Dpad / keyboard arrows navigation accessibility feature is enabled by default in the menus (alternative to the cursor)
  • Improved atmospheric simulation with a big focus on Thermals and general tweaks for the CFD
  • We added a new CFD airflow display visualization in game for aircraft that are CFD-enabled (accessible under assistances and can be mapped to a button/key)
  • New mapping for the Back to fly feature, including height gain depending on the plane situation and current altitude (below 1,000ft, 5,000ft, and 10,000ft), allowing you to quickly adjust your flight in a variety of contexts. Very useful during glider runs if you do not wish to restart the flight after having landed
  • Copilot will no longer request pushback service when it is only managing ATC communications
  • ATC UI is now enabled with COM Radio for planes lacking Nav radios
  • Live traffic planes no longer turn and fly over the airport at low altitudes before the initial climb
  • Added Departure procedures to Air traffic
  • Auto refuel at the end of the leg is no longer activated by default across all existing bush trips (can be set via RefuelOnLegStart)
  • “Wing Commander” achievement can now be unlocked passing 1,000 flight hours
  • General
    • Fixed an issue that would cause Morse sound not to work properly on some planes
    • Fixed an issue on the VNAV button that caused it to not properly sync when present on 2 glass cockpits on the same plane
    • Fixed some scenarios where we could have camera glitch when flying under bridges

The full patch notes can be found on the official site.

Microsoft Flight Simulator: 40th Anniversary Edition Update is available on Xbox One, Xbox Series X/S, and PC.
