2. Disable Hardware Acceleration

This feature offloads video to your GPU but often causes Teams video call freezing on older hardware.

  1. Teams Settings > General.
  2. Uncheck Enable GPU hardware acceleration.
  3. Restart Teams. Test a call—smooth sailing! ⭐

3. Clear Teams Cache

Corrupted cache files bog down performance. Here's how:

  • Windows: %appdata%\Microsoft\Teams > Delete contents of folders like Cache, GPUCache, IndexedDB.
  • Mac: ~/Library/Application Support/Microsoft/Teams > Same deletion.
  • Restart. Your app will rebuild fresh. 💨

4. Optimize Network Settings

For persistent Microsoft Teams video freezing:

  • Disable VPN if active—Teams hates interference.
  • In Teams: Settings > Network > Enable Reduce data usage or High quality media only on LAN.
  • Router tweak: Prioritize Teams ports (UDP 3478-3481) via QoS settings.

Ensure camera privacy settings allow Teams access:

  • Windows: Settings > Privacy > Camera > Allow apps.
  • Browser version: Check site permissions.
  • Test external webcam? Swap USB ports or try another device.

🚀 Advanced Tips to Prevent Future Freezes

Once fixed, stay ahead:

  • Join meetings early to preload video. ⏰
  • Use Teams web version as backup.
  • Monitor with Teams' built-in diagnostics: Help > Give feedback > Include logs for support.
