Turning on NDI uses 10% more CPU. I am using two pc setup so i can do the streaming on the second pc. but adding NDI actually uses more CPU.

Please don't ask me to remove some of the sources and just leave the Scene empty. this is not a fix. its a workaround. If there are actually settings or setup issues that you see in my log files. Please tell me and i will fix it. but removing sources is not a fix. Without NDI i use less CPU with my current setup than with NDI.

thank you in advance for any help.
 
Since you seem to do compositing on your game PC and use the streaming PC for encoding only, you might as well do encoding on the gaming PC directly and not use a streaming PC. You have a Turing Nvidia GPU, so you can use high quality nvenc (new) for encoding.

Preparing and sending a data stream via NDI might be more resource intensive than encoding and streamin with nvenc (new) directly. Nvenc (new) encodes directly from the frame buffer, while NDI has to download the raw data stream and send it over the network - that's probably much more load.
