Hi there, Mark, creator of Isadora here. Thanks for using the software.

Before we get into why NDI can be so heavy, can you tell us why you're using NDI in the first place? Do you need to send the video to another computer on the network? Or?

In any case, the thing about NDI is that it is quite "expensive":

First, Isadora must pull the video image from your GPU (graphics card) back into the CPU so NDI can work with it. This is inherently inefficient. (GPUs can receive video from the CPU really fast; but they simply aren't designed to go the other direction.) Please do make sure you've done what @Woland suggests in the previous post. That might help the GPU part.
But the really heavy part is compressing that high-resolution video to something that NDI can send in real time. There isn't too much you can do to make NDI faster in this regard.

I would suggest that you resize your stage to 1280x720 in the Stage Setup window and see if that helps the situation. The smaller you can make the images that NDI must compress, the less LOAD you'll see in Isadora.

Let us know if any of that helps. If not, we'll try to help you further.

Best Wishes,
Mark
