Frequently asked questions
Getting started
What is SimAtlas?
What is included in SimAtlas+?
Is SimAtlas cheaper than buying add-ons?
If you fly to many different airports, usually yes: one subscription covers the whole payware library. If you only fly one or two airports and want to keep them forever, buying those add-ons can work out better.

Performance and technical
Does SimAtlas affect my loading times / fps?
SimAtlas works just like any other add-on. The more scenery you have enabled, the longer MSFS takes to load. However, there is no additional performance impact from SimAtlas itself, only from the scenery you choose to enable.
The good news: Enabling and disabling sceneries with SimAtlas is incredibly easy. We recommend enabling only the airports you're actively flying to keep loading times fast. You can enable/disable sceneries anytime with one click. No file management needed.
FPS Impact: SimAtlas adds almost no observable FPS overhead. Any FPS impact comes purely from the scenery itself, exactly as if you'd installed it manually.
How much disk space do I need?
Each add-on ranges from a few MB to several GB. We recommend at least 50 GB of free space.
Downloaded scenery stays on your disk (even when disabled) so you can re-enable airports instantly without re-downloading. You can manually remove scenery anytime through the client if you need to free up space.
Do I need a fast internet connection?
Does SimAtlas work offline?
How does SimAtlas handle add-on updates?
Does SimAtlas install a driver?
Yes. SimAtlas installs a copy-protection driver to securely deliver your simulator packages. It is developed by Callback Technologies, whose filesystem components have been trusted by Fortune 500 companies for over two decades.
