Is there Currently an issue with the AR SDK?

I was running the Nvidia face tracking feature for several months, then it suddenly stopped working about a day before the OBS update. I’ve tried several fresh install over several days, and when added as a filter, the face tracking neither responds to stability or x-y offset. Im curious what a solution might be,

Are you talking about the auto frame capability in the NVIDIA Broadcast App or face landmark tracking SDK? These are all self contained capabilities running locally, so they shouldn’t be impacted. The AR SDK hasn’t been updated in the last two months, so there shouldn’t be any change there.
