Poor video performance on Twitch.tv.

@luetage
I submitted a bug report. -
Out of pure curiosity, I did a quick test with 6 simultaneous twitch videos playing:
https://youtu.be/PkOQjJAdQUENo big CPU/GPU issues here, and this is on a 5 year old system:
Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz, 4001 Mhz, 4 Core(s), 8 Logical Processor(s)
NVIDIA GeForce GTX 970Most of the load seems to be on the GPU process and from the ffmpeg.exe used to record the screen...
Also, the horror (oh the horror!) of having to listen to multiple nasally-voiced yobs trying to outdo one another in whooping, screaming and obscenities should earn me a medal

I tested running 5 streams at 1080p60 and 1 at 960p30 in tiled tabs (all visible at the same time) for a few minutes. All ran just fine with high quality and no stuttering/freezing, while I also had Overwatch running at ultra settings with 100-180 fps.
I'm using a Radeon 5700XT (slightly weaker than an RTX 2080) with a Ryzen 2600X. GPU usage was at 96%, but then I was also running Overwatch as mentioned above so that isn't really comparable.

Thank you very much for testing. That's very strange. It's definitely not a resource issue. With 8 open streams Vivaldi is using about 20% CPU and 60% GPU. RAM is way under my limit (32 GB).
I took a clip to show what the stutter looks like.
https://www.youtube.com/watch?v=yva4SH5UuEY&feature=youtu.beYou can clearly see it, especially in the high-motion scenes like cars moving or people running - general lag and choppiness of the playback, and occasional momentary freezes. Also, if I turn on the sound, it skips from time to time.

@ronyxs Did another test and found that it does lag for me as well, but only if I have the Twitch streams in different windows. When I put 8 windows with different streams I saw lots of lag, just like in your video. However, when I put all those streams into a single window and tiled the tabs so I could still see all 8 streams at once, the lag disappeared and all streams ran smoothly (with about the same GPU usage as when it was lagging).
-
@Komposten Thanks for checking again! So I'm not crazy then
I had no idea that I can view tiled tabs within a single window. How do you do that? I searched the settings for 'tile' and found some shortcuts for tiling the tabs: Ctrl + F6/F7/F8/F9, but nothing seems to happen when I use any of these hotkey combos.
What am I missing? -
Also no problems with AMD Radeon 2Gb

Hi, open your streams in tabs, select the tabs with Shift+Click.
In the status bar near the screen shot icon is the tile icon, choose the tiling option you like.
You can create a tab stack as well and tile this to save space in the tab bar.Cheers, mib

@mib2berlin Thanks, I didn't realize I had to select the tabs first.
And yes, tiled tabs in a single window performs way better than multiple windows. It seems to work well.@Komposten Thank you!
-
@yeppiyep You did what Komposten & mib2berlin proposed to do with the tiled tabs and you still have the problem with this method as well you mean?

Having the same problem even with one 1080p60 stream. Something is wrong with hardware accelerated decoding on all chromium based browsers. My graphics card is Radeon RX590.

Hello,I've ran into the same poor performance on Twitch.tv - which did not happened before, possibly one of the last updates did screwed something. If I watch a stream while the chat is opened too, the stream stutters very much. Closing the chat solves the issue - but maybe I don't want to actually do that, you know? In my case disabling "hardware acceleration" solved the issue apparently. I would like to mention that this did not occurred on Chrome/Brave tho'. On these 2 I can normally watch stream with chat ON while the "hardware acceleration" is enabled.
