We've found a few ways to improve performance.
Tweak #1: Clear the SceneryIndexes, SceneryCache & Content.xml
Having old cache can have a negative impact on your sim.
Navigate to:
MS Store Users: AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache
Steam Users: AppData\Roaming\Microsoft Flight Simulator
Inside this folder, find the SceneryIndexes, SceneryCache folder and Content.xml file and delete them. This will now regenerate when you launch MSFS.
For those with rolling cache enabled, try clearing and disabling.
Tweak #2:
Our tester was previously experiencing a frame rate of between 25-30FPS when testing.
By ensuring the following changes were made (outlined below) our tester was able to up the FPS rate to between 50 and 70 FPS
Graphics settings can be located within Windows Settings > Display > Graphics settings.
Our tester had an Nvidia card, so this setting would be found within the Nvidia control panel. It will need to be changed to "prefer maximum performance" as above.
And, as you can see above, the FPS rate.
Tweak #3:
Follow the following steps:
- Run CCleaner to clean up computer temp files.
- Update your GPU Graphics Drivers to the latest version.
- Eliminate All Startup Apps that are unnecessary.
- Use 4K textures from the livery manager instead of 8K textures.
Furthermore, Photogrammetry can be very resource intensive, if you're struggling for performance, disable this in the data menu.
