Prove the failure in the finished output first.
After reproducing the issue, compare rendering-lag and encoding-lag counters in the same completed OBS session. Review the local recording separately from the platform VOD.
What it may mean
Rendering lag, encoding lag, unstable frame pacing, capture behavior or destination playback may be responsible instead of the upload route.
What it does not prove
Zero network drops does not mean every stage is healthy. OBS builds and encodes frames before the network sends them.
Match the evidence before changing settings
The failure is likely before the destination network or player.
NEXT TESTInspect rendering and encoding lag in the same session log.
The ingest route, transcoding or destination playback remains in scope.
NEXT TESTRun a private destination test and compare platform health with OBS network counters.
The delivery bitrate may be too demanding for part of the audience.
NEXT TESTTest a lower platform-compliant bitrate without changing unrelated encoder settings.
One conservative free test
If rendering lag rises, create GPU headroom by capping game FPS. If encoding lag rises, test a faster preset. Change only the matching bottleneck and repeat the scene.
Separate network, render and encoder lag →Preserve the rollback
Record the original FPS cap or encoder preset and restore it when the relevant counter does not improve.

Common questions
01Can a stream stutter with zero dropped frames?+
Yes. Network-dropped frames cover only one stage. Rendering, encoding, frame pacing, destination processing and viewer playback can still cause visible stutter.
02What should I compare first?+
Compare the completed local recording, rendering-lag counter, encoding-lag counter, network-dropped-frame counter and destination VOD from the same test.
Did the relevant counters improve?
For dropped frames, encoding lag or rendering lag, compare a completed log from before and after your change. For audio and black-screen problems, inspect the recording itself; counters cannot establish picture or sound quality.
