What Causes Twitch Buffering During Live Streams?

1. Internet Connection Issues

A slow or unstable internet connection is the number one cause of Twitch buffering. Buffering occurs when the stream cannot download data fast enough to keep up with playback.

  • Low bandwidth or fluctuating speeds reduce continuous data flow

  • ISP throttling or network congestion can limit streaming quality

  • Issues with Wi-Fi such as weak signal or interference

2. Browser and App Problems

Outdated browsers, conflicting extensions, or corrupted cache files can cause Twitch videos to buffer.

  • Browser hardware acceleration may conflict with Twitch playback

  • Cache buildup slows down content loading

  • Some extensions interfere with video streaming functionality

3. Device Performance Limitations

Older or underpowered devices might struggle to decode high-quality streams in real time.

  • Insufficient CPU or GPU power causes lag

  • Running multiple background processes divides system resources

  • Outdated device drivers or software impact performance

4. Twitch Server or Platform Issues

Sometimes the problem isn’t on your end. Twitch’s servers or platform infrastructure can experience outages, overloads, or technical glitches causing buffering.

  • Regional server outages affect stream delivery

  • High traffic periods put strain on Twitch’s infrastructure

  • Platform updates or bugs occasionally disrupt streaming
