      Hi,

      I was wondering if someone could help me out with best practices for receiving NDI.
      I'm getting a feed through from another computer running touchdesigner
      we're connected through the same LAN on which no other computers are present and which is not connected to the internet. |
      I do manage to get imagery through to my system however it seems to just be at 5 - 8 FPS

      I'm getting a very laggy feed through my ndi watcher, I've tried adjusting some parameters, like the framerate of Isadora or the general service tasks.
      The bandwidth from the ndi actor. but I never seem to get rid of the stutter. Also on their end I've tried to adjust the frame rate, etc. Is there anything I'm forgetting to check or adjust? 

      Or could it be that my system is just old or incompatible with their newer MacBook?


      my system:
      Windows 10
      intel i7-8750H
      32 GB RAM
      Nvidia GTX 1060

      Their system:
      Apple Macbook pro M1
      OS: Ventura 13.0

      would be amazing if someone could share some of their best practices :)

        I would recommend installing Isadora on the Mac, and creating a simple animation of a Shapes actor crossing the stage in a loop. Then turn on NDI output in the Stage setup window.
        Test receiving NDI from this new source ( I just did this with a mac mini on wifi ) I am getting 30fps with a 1080p feed.

        If it works with your Isadora NDI feed, then you may have issues with your other source.

          Thank you so much for your answer, I've been trying and testing some things and your suggestion of testing Isadora to Isadora was very useful. there seems to be an ndi compatibility issue between touchdesigner and Isadora or something. right now I'm using syphon on the Touch macbook to get the visuals into Isadora and using ndi to send it to the other computer.

          So syphon Touch > Isadora gives smoother results than using NDI it seems.

          Hope this helps others as well who run into this problem
