Observe both workloads
The OBS performance guide explains that the application needs GPU resources to composite and render a scene. A game or video source can appear smooth while the additional capture workload struggles. Therefore a viewer report that the source itself looked fine does not rule out a local production bottleneck. Keep the source observation, OBS warning or statistics and resulting recorded output as separate pieces of evidence.
Reduce one known competing task
For an original controlled test, use the same permitted source and recording settings, then close only a known user opened GPU heavy background task. Compare a short output and the relevant OBS observations before and after. Alternatively simplify an unnecessarily complex scene as a separate experiment. Do not change resolution, encoder and every source at once, because a better result would then leave the effective change unclear. These are test designs, not results from a recording performed here.
Keep local production distinct from delivery
An encoding overloaded warning belongs in a different part of the investigation from a remote viewer network error. A lower upload bitrate is not a universal remedy for a compositor which cannot keep up, and a powerful CPU does not make GPU resources unlimited. Use the applicable OBS documentation and preserve the original settings so changes are reversible. This article does not promise a particular frame rate or claim that any commercial programme may be captured or rebroadcast.
