In Task Manager, my "Send" is stuck at average 50-70 Mbps (jumps around +-30%) when operating the software to send dynamic video output (and with static content as well), while using LAN Speed Test it goes up to 500 Mbps write 900Mbps read when interacting with a folder on the stream PC. (from the gaming PC)
edit: Minor additions. Also sending to a different OBS instance on the same PC seems to work without problem on both systems btw.
edit: Same issues when relaying video from stream PC to game PC. Although max Mbps sent is even lower.

Chiming in from the DistroAV team since these has been reported within the discord server. I normally test within Windows 10 with all updates being disabled to avoid any variables.
There has always been the knowledge of windows 11 messing things from time to time.. specially when OBS ran in the background and not as the focused window.
All of you with issues mind checking the latest windows updates and the windows build of your systems?
Reporting within the Github would be better yet we can't ask every user to do that. Once I have enough information I'll be creating a bug report.

Here you go. Let me know what else you need. OBS 31.1.2. Note that Tivvy is reporting the issue with Windows 10. I use all CPU encoding btw. Switching to NVENC shows the exact same issues. Must be a Windows network thing, has to be. Single PC is smooth as silk.

For the record, the runtime update does not address the issue as I had described.
As of right now, I need to remove two updates from Win11 23H2, KB5063878 and KB5063875. Removing '878 by itself isn't enough. If '875 is present, it must also be removed for current NDI (in the context of DistroAV) to work properly.

PSA to those affected by the recent regression introduced by Windows update : KB5063709 and KB5063878.
The recommended fix is to actively select the "single-TCP" or UDP, using the NDI Access Manager tool (tab Advanced).
Follow the "how-to" process by DistroAV
These update will keep re-installing and sometimes cannot be uninstalled

Is this a band-aid that will be fixed by Microsoft in the future?

Sorry for my reaction there. I mean, seriously, after all, this is Microsoft we're talking about here.

This is a Temporary solution until Microsoft fix their issue.
The issue is so deep-level that we cannot even fix-it in the DistroAV code.
I've been working on this problem all day and just discovered the known issue from Microsoft. The only thing that works for me is Single-TCP. I have to disable all other protocols in Access Manager. I tried just disabling Reliable UDP (such an ironic name) and video was better but still not smooth.

Hello everyone,
Do not install NVidia's Newest driver 581.29 It cause distro AV to studder while gaming. If you did update would suggest redownloading 581.15(or the pervious driver depending on your GPU), also I don't know if AMD has this problem(because I have NVidia in both of my systems).

Curious, how recent are you on your Windows updates, and which release of Windows are you running? There's a chance you may be looking at entirely the wrong problem. There have been serious problems with NDI thanks to some bum updates last month's Patch Tuesday (August 2025). One workaround is to use the NDI bundle's Access Manager and setting inputs to "single TCP". I did, arguably, the right thing by keeping those bum updates off my computers entirely because it has even more serious problems, like either seeing SSDs fall offline which a reboot can bring back, SSDs fall offline which a reboot can bring back but with corrupted data, and worse, it outright turns SSDs into very expensive and very useless bricks. This affects primarily drives with PHISION controller chips.
I am going to run the Windows Update rigamarole to see if it hoses my NDI setup.
More soon on both the NDI-vs-Microsoft and NVidia (which I have not gone past 575.whatever yet) fronts, separately and together.
