I have a Navigraph subscription, which I used extensively in MSFS 2020/2024. However, in XP12, the Navigraph plugin is causing a rhythmic stutter - roughly once every second. It really impacts performance and makes it difficult to use. Has anyone found a workaround for this? As it stands, I can't use Navigraph in XP12 with that kind of stutter.

I dont have any problems with navigraph simlink plugin.

 

No issues here with a dinosaur of a system.  Perhaps some "disagreement" amongst plug-in's?  The Simlink updates often.  Do you have the latest version?

I'm having the same issue using my second copy of XP12 which is default, used for beta testing.  I do have the latest version.

I have no issues with Simlink on either Mac or Windows. Keep it updated.

That’s weird; I also never had any such issues because of the simlink-plugin…

Really odd nobody seems to have this issue.  Soon as I disable simlink the stutter goes.  I posted on the Navigraph forum.

Weird. Navigraph support have made some suggestions but nothing worked so far.

 

Just in case one of you clever people can help with this stutter, I have created a couple of videos to show the problem.

Firstly in Plugin Admin under the performance tab you can see Simlink causing the stutter every one second. In the second video you see the XP12 MicroProfiler showing the stutter causing a long Frame Time every one second.

 

 

Huge thanks to Navigraph for the excellent support. I had XP12 installed on an external drive that was running at 100% usage, which caused Navigraph to constantly ping XP12, trying to get time for itself.  Navigraph helped by installing a new copy of XP12 on my internal SSD — and now the stutter is gone! The sim runs much smoother too.

The root sim should definitely be on the ssd. Use symlinks in the root sim folders pointing to the usb drive if storage space is a problem.
