Even though you are not dropping any frames, please be aware that in many cases, wireless connections can cause issues because of their unstable nature. Streaming really requires a stable connection. Often wireless connections are fine, but if you have problems, the first troubleshooting step would be to switch to wired. We highly recommend streaming on wired connections.
At least one of your audio devices has a sample rate that doesn't match the rest. This can result in audio drift over time or sound distortion. Check your audio devices in Windows settings (both Playback and Recording) and ensure the Default Format (under Advanced) is consistent. 48000 Hz is recommended.
OBS Sample Rate:
44100 Hz
Speakers (Realtek High Definition Audio):
48000 Hz
Microphone (USB Audio Device):
48000 Hz
Uncheck Look-ahead and set your B-Frames to 2.
If your trying to get better quality and the content is high motion, you need to increase your bitrate or lower your frame rate. NVIDIA
