Fix Twitch Constant Buffering & Lag (Even on Good Internet)

Updated: 11/29/2025

You are watching a stream, and every 10 seconds, the video freezes and the loading circle spins. You check your speed test—100Mbps. So why is Twitch lagging? This is rarely an issue with your download speed. It is usually a conflict with Twitch's 'Low Latency' player or a browser setting that is choking the video buffer.

Method 1: Disable Low Latency Mode

Low Latency Mode reduces the delay between you and the streamer, allowing you to chat in real-time. However, it leaves zero room for error. If your internet hiccups for 1 millisecond, the stream buffers.

Step 1: Settings

Click the Gear Icon on the video player.

Step 2: Advanced

Select Advanced. Look for Low Latency and toggle it OFF. This increases the delay by about 2-3 seconds but builds a massive buffer safety net.

Method 2: Force a Different DNS

Some ISPs throttle traffic specifically from Twitch servers. Switching to Google's phonebook bypasses the throttle.

Change this in your Windows Network Adapter settings (IPv4) or directly in your Router to fix it for all devices.

Method 3: Hardware Acceleration Check

If your CPU is old, decoding 1080p60 streams is hard work. Ensure your Graphics Card is doing the heavy lifting.

• Chrome: Settings > System > Toggle 'Use graphics acceleration' ON.
• Firefox: Settings > General > Performance > Uncheck 'Use recommended' > Check 'Use hardware acceleration'.
