8 Easy Fixes to Apply when Facing High CPU Usage on Twitch

  • Twitch is a live streaming watched by millions of people around the world.
  • But some have noticed that using the website takes up a lot of CPU resources.
  • This guide details the multiples methods to fixing this problem.

Twitch is a live streaming service that has millions of active viewers every month. People from all over the world can hop on the website and play their favorite video games to an audience.

While it was originally known to be a gaming site, it has since grown to incorporate other types of content like cooking, music, and even just chatting. Since its creation, other tech companies have tried to create something similar.

YouTube created YouTube Gaming and established its own streaming service. But no matter how hard they try, the king of the hill is still Twitch.

Is watching Twitch CPU intensive?

Yes, it can be. Whether you’re watching or streaming on Twitch, it’s usually due to certain settings. If your settings are particularly high, like 1080p at 60 FPS, then yes, you will see high CPU usage.

The first thing you can do to lower CPU usage is to choose a less intense stream setting. So instead of watching a stream on 1080p at 60 FPS, try out 720p at 30 FPS.

The second thing that you can do is update your browser to the latest version. You can do this by going to a browser’s respective installation website and downloading the new version.

That should fix most of your problems, but if that doesn’t work, this guide will show you a series of browser-specific solutions that you can try out.
