Strange thing here is that after updating to 79 version, the performance when watching youtube is worse with 'h264ify' extension enabled.
In previous versions it was the opposite situation.
*The best performance for me is now in Dev version with 'h264ify' extension disabled and with 'static indicator' flag enabled.

Since 79 version avc1 videos on youtube overload CPU here(even without the animated tab indicator).
I checked it in Chrome and in Edge Canary without any issues.

I have this problem in the latest version does anyone else have this issue where youtube is just devouring cpu despite being on the latest version? Also I've looked around and haven't found a solid this has fixed it fix.

Try to install VP9 Extension, which allows the GPU to take the most workload, releasing CPU (especially in 4K contents).

@cabusopera how does this help with youtube? I don't understand since this is an app not something I can run or attach to opera as an extension and call it a day. This is a video player that isn't youtube and doesn't have youtube... I guess I just don't see what this suggestion was suggesting when the issue is about youtube.

@l1l-st4bb13s Description:

Play VP9 videos in any video app on your Windows 10 device. VP9 is a popular video codec for streaming over the internet. These VP9 Video Extensions are designed to take advantage of hardware capabilities on newer devices. For devices that don’t have hardware support for VP9 videos, software support is provided, but the playback experience might vary based on the video resolution and device performance. These extensions also let you encode VP8 and VP9 content on devices that don’t have a hardware-based video encoder.

Applies to web browser content also

@l1l-st4bb13s Goto opera://flags and choose "reset all", Goto the URL opera://settings/system, and make sure "hardware acceleration" is on. Then, restart Opera and goto opera://gpu. Any difference?

@l1l-st4bb13s What CPU and Operating System do you use?

@l1l-st4bb13s If even after flags reset and enabling hardware acceleration in settings, opera://gpu says that only software acceleration is used, then it's probably the cause of the problem.

@l1l-st4bb13s Do the other Chromium browsers (e.g., Edge) also reflect Software Acceleration? In that case, I suspect that you have the problem on Windows or the wrong BIOS configuration,
Set your BIOS by default and then do a full system update (Windows Update) or consider a reinstallation of the Operating System, because I don't think that the browser is your problem. Browsers reflect the system’s default acceleration, and this is enabled by default on Windows.

@l1l-st4bb13s There's something Chromium doesn't like about your Radeon Vega Mobile GPU/drivers. You're running in software-only mode, so everything is going to use more CPU.

Are you sure you've enabled opera://flags/#ignore-gpu-blocklist and set opera://flags/#use-angle to D3D9 for example?

I'd also go right to the AMD website to get the latest GPU driver to see if that helps (with default settings or the above settings). Or, you can try the latest GPU from your PC's manufacturer's website. Sometimes that will work.

@jaswantwe said in High cpu usage watching youtube:

Make sure hardware acceleration is enabled or this won't work
(If you can't find hardware acc, go here opera://settings and type in "hardware acceleration")
Go to opera://flags/#ignore-gpu-blocklist
Enable that setting, relaunch and you should be good.

Thankyou! This worked for me, current 89.0.447.83 W10 64 bit - years after this thread began!

Thing is, for years I've had no trouble, until about 3 weeks ago. I could have 40 tabs open and still play YouTube. Since when it deteriorated to the point where just one tab would drop frames and eventually stall using 100% CPU.

Clearing cache and a restart would then be needed before I could browse anything

Your fixes worked - although I still note load is halved if I hover over the You Tube animated tab. Alas I can find no setting or flag to fix that in the current version.
