Troubleshooting & FAQ (1)
TroubleshootingHow to fix OBS browser source stuttering when OBS window loses focus on Windows 11?
This is caused by Windows enabling Efficiency Mode on obs-browser-page.exe processes, throttling them when OBS loses focus. Workaround: In Task Manager > Details tab, right-click each obs-browser-page.exe process, choose 'Set priority' > 'High', then disable 'Efficiency mode' from the right-click menu. Note: These settings reset when OBS restarts. Track OBS issue #12982 for a permanent fix.
