CPU loaded about 70-90% when watching videos on Yotube

Charodiy_91

Hello. How I can enable GPU hardware acceleration or find out is it enabled and don't work properly? When I watch videos on Youtube my FX 8350 loaded almost at 90% (from 60 to sometimes 95%). I have GPU GTX 960 and want to turn it to accselerate video!
Thanks!

hardware acceleration

Just go in settings and type hardware in the search box. It's in the Webpages settings.
To be extra sure, also go vivaldi://flags and do the same there.
vivaldi://gpu will show if your gpu is in use, if it's unsupported etc.

@iAN-CooG So what you can say, what wrong?

@Charodiy_91 It looks like you have enabled Hardware Acceleration. So should be no problem, and your system is powerful enough to play video with no issues at all.

But there is a difference between videos, what codec they use. And also how large you are playing them back. Please give an example of a video using 60-95% of CPU.

Use Shift+ESC to show Vivaldi Task Manager. You should have a task called "GPU Process". How much CPU does it use?

In my case, vídeo YouTube in full screen 3% GPU AMD Radeon 2Gb

@Pathduck Hi, I take some screenshots from Vivaldi Task Manager with YouTube video ON:

Hi, I checked https://www.youtube.com/watch?v=Mb4o8rwfTBY Everspace stream and get same result:
CPU ~70
GPU ~25
Even in window mode, go to max in full screen, but the same with Chrome and the video is 720p. Really strange.
The example from @Catweazle is much lower.
No idea what happen.

@Charodiy_91 The GPU process shows you have HW acceleration enabled. I see nothing special about the numbers. Note that the Vivaldi Task Manager (VTM) shows CPU usage out of total cores, so with 8 cores, 100% would be 1/8 out of 800%. Does that make sense? So you can basically divide that number by your number of logical processors.

Windows Task Manager or a better tool like Process Explorer shows the numbers differently (out of total), and more accurate in my opinion.

Maybe a bit more CPU usage than I'm seeing here on my 2015-spec i7-4790K and a GTX970. But nothing major. That video gives me ~30-50% in VTM. In PE it shows as ~10%.

Video is only 720p but it's also 60fps which makes a lot of difference.

I would try to do the same test in a Guest View window to exclude any extensions like the Video Downloader etc causing issues. And why are you still running the "Vivaldi PiP extension", it should be redundant now?

I would also go through your NVidia control panel setting and ensure you have all Globals set to default.

@Pathduck
Ah, thanks, thought Vivaldi taskmanager shows 100% as full load.
My system process monitor show my i7 dual mobile CPU is waiting for more work.

Cheers, mib

@mib2berlin Yes, on heavy sites like WebGL demos and so on you will often get over 100%

But when it comes to a certain point most of the load is in the GPU process anyway, so this is the bottleneck and not the CPU, so framerate will be dropping while CPU is doing very little...

@Charodiy_91 playing that video at 720p60 here (i7-7700) consumes no more than 10% CPU at max, but stats for nerds show it is using the vp9 codec while your gpu page doesn't list it (in Video acceleration information). Maybe related to vp9 videos?

Charodiy_91

@mib2berlin Thanks, try to figure out what the reason of overload,

What you mining about "Vivaldi PiP extension"?, it's dont activated via Extensions, or I don't understand something?

@npro Hi, how do you understand that my videocard doesn't support accelerationof this type of video? Also want to ask whre I can find waht types of video can support vidaeocard (In drivers, or on site)?

Charodiy_91

I fond some site from Nvidia - Video Encode and Decode GPU Support Matrix (https://developer.nvidia.com/video-encode-decode-gpu-support-matrix), and really GTX 960 don't support some sort of VP9 (10, 12 bit) also H.265 (4:4:4). So as I understand decoding/encoding of this formats falls to shoulders of CPU...

@Charodiy_91
Nice find.
I think an overview of all major cards should be in the Vivaldi help system so user post problems here can send to the corresponding page.
All think it is Vivaldi bug or something but it is only hardware limitation.

Windows Task Manager is a better indicator of how much of your CPU, GPU, etc. you're using. Maybe try opening that instead so you can see what percentage is actually being used, full system wise. Something to note too, I have noticed before that having certain antivirus programs sometimes creates problems as well, as far as spiking CPU, and GPU usage. Just something I've noticed in the past.
