UPDATE – Some reports suggest uninstalling all World Updates and Photogrammetries via in-sim Content Manager recovers low FPS issues regardless of where you fly. For those users still suffering serious performance degradation issues, we recommend first deleting cloud saves and then reinstalling MSFS. Deleting cloud saves will reset all your in-sim settings, logbook entries, and joystick bindings back to defaults. After MSFS reinstall, apply everything as described in our Best Graphics Settings Guide and this Performance Boost Tricks article.
After performance drop issues with several official updates during 2021, the community around Microsoft Flight Simulator started to hunt down all kinds of tweaks to enhance the flying experience. The official troubleshooting site is good to check out frequently for new updates. If experiencing slow download speed while downloading the MSFS or its big update files such as Sim Update and World Update, do the following tutorial. A loop issue during in-sim downloads can be fixed by force quitting the MSFS installer. The download will resume where left off after relaunching the sim. Before starting to update, make sure the in-game option Bandwidth is set to UNLIMITED under the GENERAL OPTIONS – DATA settings, then close MSFS and do the following.
- In the Windows search bar, type “Delivery Optimisation”.
- Select “Delivery Optimisation advanced settings”.
- Set both Percentage of measured bandwidth limiters to 100%.
- In the Windows search bar, type “Command Prompt”.
- In the menu select “Run as administrator”.
- Type: sfc /scannow and wait for the progress to complete.
- Type: netsh int tcp set global autotuninglevel=normal
- By pressing Enter, you should receive an “OK.” message.
- Reboot your computer for this change to take effect.
Here are gathered some of the performance boost tricks I’ve tested, and I think you could also try and see if it helps to gain a bit smoother performance and fewer problems at your own risk. If you realize that no change happens to your performance, always change the settings you made back to default ones. I’m using all the tricks introduced below with everything as described on the Best Graphics Settings Guide as well, and I’m really happy with the overall performance of the MSFS.
