video delay, even when just self-viewing

Hello @leedtan,

Welcome to the Zoom Community! We're happy to have you here.

You can try these troubleshooting steps:

1. Close other heavy apps/processes

   • Background apps (especially CPU/GPU-heavy) can cause Zoom to lag.

   • Open Task Manager (Ctrl+Shift+Esc) and close anything unnecessary, especially video editors, browsers with many tabs, or gaming apps.

2. Check your Zoom Video Settings

   • In Zoom, go to Settings → Video.

   • Disable “Enable HD” — HD video can cause delays if your system or connection can’t handle it.

   • Disable “Touch up my appearance” or any video filters that might add processing overhead.

3. Check your Internet connection

   • Although your camera app runs locally, Zoom video processing may be affected by network issues.

   • Try connecting via Ethernet cable instead of Wi-Fi if possible.

   • Run a speed test and ensure your upload/download speeds are decent.

4. Update your graphics drivers

   • Even if your camera is fine standalone, outdated GPU drivers can cause delays with video encoding/decoding in Zoom.

   • Go to your GPU manufacturer’s website (Intel, NVIDIA, AMD) and download the latest drivers.

5. Change Zoom video rendering settings

   • In Zoom settings → Video → Advanced:

     • Toggle “Use hardware acceleration for video processing” on or off (test both).

     • Toggle “Use hardware acceleration for receiving video” on or off.

6. Try a different USB port or camera

   • If you’re using an external webcam, try switching USB ports (USB 3.0 vs. USB 2.0).

   • Sometimes ports cause delays due to bandwidth or driver issues.

7. Test with a clean Zoom install

   • Uninstall Zoom fully.

   • Download the latest Zoom installer from the official site and reinstall.
