Microsoft's August 2025 Patch has introduced over 100 vulnerabilities, including a zero-day exploit affecting Windows Kerberos. Users have reported significant performance declines in streaming applications, particularly OBS and NDI Tools, characterized by severe lag and stuttering during streaming sessions when using the NDI protocol. Microsoft acknowledged that these issues arise after installing the update, specifically noting that severe stuttering, lag, and choppy audio/video may occur when using NDI for streaming or transferring audio/video feeds between PCs. The NDI team confirmed a drop in traffic linked to the Reliable User Datagram Protocol (RUDP), which is the default communication method for NDI, with performance degradation observed exclusively with RUDP connections. Microsoft has suggested potential workarounds, but a definitive fix may take time to implement.
