Inconsistent Freezing in Long-Term Operation: Looking for advice on optimizing Video Device Out / NDI / Spout setup

Beginners

Hi everyone,

I am experiencing an issue where my TouchDesigner project becomes heavy or freezes after long-term operation. I would appreciate any advice or insights into my current setup and logs.

  • The project involves real-time video I/O (UltraStudio, NDI, and Spout).

  • I recently realized that leaving the network editor open was adding unnecessary load, so I will be switching to Perform Mode for future operations.

  • No specific triggers for the freeze have been identified yet.

[System Specs]

  • TouchDesigner Build: 2023.11340

  • OS: Windows 11 24H2

  • CPU: Intel Core i9-14900HX

  • GPU: NVIDIA GeForce RTX 4090 Laptop

  • RAM: 32GB

[Diagnostic Findings] According to the Performance Monitor (stats.txt attached), the following operators show higher loads, though they don’t seem to exceed frame time limits immediately:

  • Video Device Out (Outputting to UltraStudio)

  • NDI Out

Syphon/Spout In (Receiving frames from a Python-based application)

[Attached Files]

  • stats.txt: Performance Monitor log.

  • Report.wer: Windows Error Report (since no .dmp file was generated by TouchDesigner).

[Questions]

  1. Are there known stability issues with the combination of Windows 24H2 and this specific build of TouchDesigner?

  2. Are there any best practices for long-term stability when using Video Device Out and NDI simultaneously?

  3. If the freeze occurs again without a .dmp file, are there any specific logs I should look for to identify if it’s a GPU TDR (Timeout Detection and Recovery) issue?

Hi @nosukes67 - if you open Task Manager when TouchDesigner is in this state and right-click on the TouchDesigner process there, you’ll see an option to create a .dmp file. If you could attach that, that should give us some more information. Let us know if TouchDesigner was fully frozen or sluggish when you created the .dmp file.

Hi @bangnoise Thank you for replying. Since the freezing issue is not consistently reproducible, I have not been able to obtain a .dmp file of the symptom yet. Regarding the state of the software when it occurred, TouchDesigner was fully frozen.

Thanks - if you could grab a .dmp file through Task Manager the next time it happens, we can take a look.
