New airac makes MSFS stutter so hard

If I install the nav data to the MSFS, the sim has hard stutters, if i unistall it doesnt, i tried to use default aircraft and i have the same problem, I delete all comunity files and let the navigraph folders only and Its not solved neither, the sim only works fine if i dont have any navigraph airac installed


sorry to hear but this can be thousands of reasons. When you look in the MSFS forum you will find many, many, many different reasons and also many, many, many different solutions.

We have received no report about performance issues since we have started with this update service. Therefore it is very unlikely that this has really something todo with the data.

We have no possibility to check what happened behind due the lack of log information. Also, we no nothing about your system and therefore it’s hard (honestely nearly impossible) to give you any recommendation. As you see here in the forum, no such issues are reported since a very, very long time.

Sorry, that I have no solution for you

thanks for the answer, after several days and just after send my last post, i found the answer.

The problem that i detected its that the SIDS and STARs for some airports had gone, so I try to found a reason for that, and finally I found a solution.

The first problem its that the reason of the SIDs and STARs was a corrupted file called “content.xml” found here:


Now you have to do this:

Remove Navigraph AIRAC using NavData NavCenter. Delete Content.xml. Restart sim. Confirm you see correct NavData using default NavBlue Database. Shut down sim. Reinstall NG AIRAC using NavData NavCenter. Restart sim and confirm you’re seeing NavData (try outside US as that’s where NG really shines).

With all this done, the stutters are gone, and the SIDs and STARs are back.

Kind regards, I spect that this info will be usefull for someone with the same problem!
