High CPU Usage While Playing Videos On Youtube

Description of the issue: High CPU Usage While Playing Videos On Youtube

Exact URL of the website in question: https://www.youtube.com/watch?v=SJ_pXT-L5IE

Did the issue present with default Shields settings? (yes/no) Yes

Does the site function as expected when Shields are turned off? No

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no): No

Does the site work as expected when using Chrome? I don’t have chrome but it works with firefox

Brave version (check About Brave): [Version 1.32.113 Chromium: 96.0.4664.45 (Official Build) (64-bit)]

Is Hardware acceleration enabled in brave://settings/system ? Does restarting Brave, then opening the YT page and select between 720p/1080p to see if it helps lowering the resolution.

Which GPU do you have?

  • Hardware Acceleration Is Currently Disabled
  • Enabling Hardware Acceleration Only Makes The Situation Worse
  • Restarting Brave Doesn’t Help
  • 720p uses a little lesser CPU than 1080p

Switch the GPU used by Brave to the Radeon ? via the graphics settings in windows https://support.google.com/chrome/thread/77636044/chrome-to-use-specific-gpu?hl=en

If GPU isn’t used, CPU usage will increase (its the tradeoff here). Intel graphics can be quite buggy regardless of browser you use.

Forcing h264 might also help perf (via an extension); https://chrome.google.com/webstore/detail/enhanced-h264ify/omkfmpieigblcllmkgbflkikinpkodlk?hl=en

Actually everything was fine till few days back, i am using brave for over 6 months now. This issue started just this week, also i can now see ZOOM is also using a lot of CPU so it can be some other issue too maybe i should ask on Microsoft forum.
