1. Enable Game Mode for maximum gaming performance. Game Mode can be enabled via the Windows "Settings" app, under Gaming > Game Mode.
2. 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: 48000 Hz
VoiceMeeter Input (VB-Audio VoiceMeeter VAIO): 48000 Hz
Microphone Array (Zet Koradji Pro): 96000 Hz
3. Your gigabit-capable network card is only connecting at 100mbps. This may indicate a bad network cable or outdated router / switch which could be impacting network performance.
4. Run OBS as Administrator. Right click on the OBS shortcut, properties, advanced, check box, ok, apply, ok.
5. OBS Settings > Advanced > change Color Space from sRGB to Rec. 709.
6. Change the resolution on your webcam from 1920x1080 to 1280x720 or lower if possible (such as 176x144) and then downscale it from there if necessary. This should also allow you to change the FPS on your cam to 60 FPS to match your output.
7. If you're gaming on your non-60 Hz screens and still having this issue after the above changes, this *may* be due to FPS conversion from 165 or 75 to 60 (4/11 or 4/5). Try 120 or 60 Hz/FPS.
