If you use OBS to stream, and most of all if you're hooking up multiple PCs to broadcast, you may have noticed "severe stuttering, lag, and choppy audio/video". According to the latest Windows release known issues, you aren't the only one.
As pointed out in the latest Windows 11 Version 24H2 update post, OS build 26100.4946 (which launched on August 12) has broken NDI use for some streamers. Over in forums like the VideoEngineering Subreddit, users have been complaining about 'sudden lag and framedrops' in NDI streams for a while now.
