GTNXi stutter

[jetsep]

Hi,
I'm on 1.1.0.7 with Navigraph integration.
When using it on the Blackbird C310R I get a repeatable stutter every few seconds. It's like every 5 secs. a 0.5 sec long stop. VERY annoying. Any other GPS available on the plane will not cause the issue.
RTX3090ti even if I frankly doubt it has anything to do with it...

EDIT: same problem with the A2A Comanche and same outcome: using a different GPS in the Options sorts the problem. No stutters.

Frustrating.

Hello,

Which antivirus are you using? What are your full system specs, including the disk drives and their type (HDD, SSD, M.2)
The last question, have you applied the performance improvements/antivirus exclusions, as started in the manual/forum?

Hi, 
Windows Defender is the only antivirus.
Performance improvements: both FlightSimulator.exe and gtn_simulator.exe exceptions added to Windows Defender

Thank you, on which drive is the MSFS LocalState folder located? Please note, this is not the LocalCache folder.
For a MSFS purchased from Windows Store, this is the default location:

C:\Users\%username%\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\Packages

Where %username% is your username

I have good news.
Deleting the Direct X Shader Cache in Windows system -> Storage -> Temp files...apparently is getting things back to normal. So far so good. Fluid also with the GTNXi live.

BTW the LocalState is exactly in the path you described.

Thank you for letting us know. We are glad to hear this, please enjoy the TDS GTNXi Pro.

Unfortunately we are back to stutters as described in my initial post.
This time I took time to investigate deeper.
Stutter happening with any plane using the TDS GPS.
If I kill the related running task in the task manager (TDS...gps...) everything is back to smooth. This imply that the rest of the configuration in the PC is ok. Loading and using any plane that does not use TDS gps will not show any stuttering during flight. This behavior is consistent and can be replicated anytime.
Within the document folder, both units txt.log file read similar and are reporting an error in writing a file:

Is this info of any help?

Hello,

Unfortunately the log file is not relevant to the situation, as the events seem very far off.
Since there was acceptable performance for quite some time, something else must have happened in between, which is internal to your system, configuration.

On which drive type is the LocalState folder located? The best solution would be to move it to a faster drive, as in a M.2, which we highly recommend.

Hi,
C:\Users\%username%\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\Packages
That's an M.2 drive. Specs in previous posts.

Thank you, can you please confirm that the folder:
C:\Users\%username%\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\Packages\TDS-GTNXi-Gauge\work
Is not aliased to another drive?

If it is not, then another test is to temporarily disable the antivirus real time protection.
