1. In Windows, we recommend that "Game Mode" be enabled. Game Mode can be enabled via the Windows "Settings" app, under Gaming > Game Mode.
2. Audio buffering hit the maximum value. This can be an indicator of very high system load and may affect stream latency or cause individual audio sources to stop working. Keep an eye on CPU usage especially, and close any irrelevant background programs if needed.
Occasionally, this can be caused by incorrect device timestamps. Restart OBS to reset buffering. Source affected (potential cause): Interface Mic
3. Your GPU is maxed out and OBS can't render/encode scenes fast enough (4.2%). Running a game without vertical sync or a frame rate limiter will frequently cause performance issues with OBS because your GPU will be maxed out. OBS requires a little GPU to render your scene.
Enable G\V-sync and/or set a reasonable frame rate limit (120, 60) that your GPU can handle without hitting 100% usage.
If that's not enough you may also need to turn down some of the video quality options in the game. If you are experiencing issues in general while using OBS, your GPU may be overloaded for the settings you are trying to use.
4. Record with NVENC because the skipped encoded frames were on with QuickSync. See #5
5. Disable Multipass by setting it to single pass and also disable look-ahead and aq for streaming and recording. Those use additional GPU.
6. Set your stream rate control to CBR.
