Why Is My Video Loading Slower in Chrome?

The main reason can be your internet connection. Streaming videos smoothly requires a pretty strong internet connection. A slow or unstable connection can cause the video to buffer a lot.

So make sure your internet connection is sufficient to play the videos on your browser.

Another reason can be the website itself. The playback of a video depends on the video player a website uses. In such a case, try searching for the video on other websites and play it there.

An excessive amount of caches can be the reason too. Clear the browser caches by following the steps mentioned above.

You can also try closing other tabs in order to allocate the bandwidth on playing the video.
