1. The Hardware-accelerated GPU scheduling ("HAGS") feature in Windows is currently known to cause performance and capture issues with OBS, games and overlay tools. We recommend disabling it via
these instructions as a troubleshooting step. Be sure to restart your PC after disabling it.
2. Change the refresh rate on your LG from 144 Hz to 120 Hz.
3. 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 background programs if needed. Occasionally, this can be caused by incorrect device timestamps. Restart OBS to reset buffering.

4. Make sure that all 6 of your plugs are compatible with OBS 32.2.2 and up-to-date.
5. Run OBS as Admin.
6. Don't ignore service
bitrate limits. Change your Twitch bitrate to 6000.
7. Settings > Output > Encoder Settings > Set Multipass Mode to Single Pass and disable Look-ahead and Adaptive Quantization. Those all use additional GPU.
If still having issues, provide a new log.
