jit.ndi.send~ audio high cpu usage (windows)

[matcham]

If I open jit.ndi.send.maxhelp and turn on audio, Max Audio Status windows shows a very high CPU usage (more than 62%).
resulting in glitchy audio.
But in system task manager, Max takes only 0.3 % of CPU

no other patch or app is running, I've tried with many different audio interfaces and drivers (ASIO/mme/ ...) : same issue.
I'm pretty sure this used to work smoothly on the same computer last year (with jit.ndi 0.1)

here are my Max support informations :

same issue on Mac, latest versions of everything (os, Max, ndi, ..)

Same issue on Mac.
Could it be related to the fact that I have on both Os beta versions of Max 8.2.0 ?
does it work fine on Max release 8.1.11 ?

Hi Matcham -

I am running Max 8.1.11 on OSX Catalina 10.15.7 and am seeing the same high cpu usage (65-80%). CPU Usage function within Max/MSP shows [jit.ndi.send~] is contributing to 99.7% of processing power.
