Multi Monitors + Multi Video stutter/VPU issues

[Pokora]

I've had this issue for a while, but thought it might be my system installation fault. Recently made a fresh Windows 10 (Windows 10 OS Version 2009 (Build 19042.746)) install and fresh Vivaldi and Chrome installs, and it turns out the issue remained as it was.

What happens is: Whenever I have two windows on different monitors with 2 videos playing, they will slow down, stutter, stop and get stuck loading for a few seconds etc. It's unusable. I've checked with extensions I use, with all of them turned off and on a standalone installation of Vivaldi (all 3.6.2165.36 (Stable channel) (64-bit)). I've tried with both #ignore-gpu-blocklist enabled and disabled, as it was the most common suggestion I saw.

To compare, Chrome (88.0.4324.150) with same settings (meaning no extra flags, just the two windows with 1 video tab each) works flawlessly.

This persists on any type of video content. Any 2 YT videos, any 2 Twitch streams, Twitch + YT etc.

Digging somewhat deeper I took a look at GPU and VPU usage in both scenarios. GPU usage across both was similar. VPU (The video usage) on other hand was completely broken on Vivaldi. The spikes (and video stutter) were the worst when moving mouse over and out of the videos, and especially when moving mouse from one window to other. The stable bit was me not touching anything, with the 2 vids taking up ~30% of VPU.

In comparison, Chrome used ~50% stable no matter what was happening.

The GPU in question is an RTX 2070 with (currently) 461.09 driver (Jan 07, 2021). Don't think a specific driver version is at fault - this has persisted for 6 months now or more from what I remember.

I've uploaded both browsers gpu report in hopes somebody might notice something faulty: Vivaldi report, Chrome report

Not sure what else I can try or provide here to help finding a solution to this. Please ask any questions!

Hi, testing with two displays and two youtube windows I have no stuttering at all on my GTX 760. I have a RTX 2060 but I don´t use it for display but for rendering 3D content.
EVGA Precision X1 don´t show VID usage but I am not familiar with this software. Windows Taskmanager show constantly 30% GPU usage but no Video En/Decode usage although hardware acceleration is enabled.
If I find some time I will change my displays to the RTX 2060 tomorrow.

Windows 10 Pro/64 20H2 19042.789
Intel i5 3570K 16 GB RAM
GTX 760 4 GB /Display card
RTX 2060
Driver 460.79

Cheers, mib

Hi there mib. If you have Precision and want to see more graphs, you can click on the red '1' (in my case) button on top of the window and select wanted stats.
You can also use Nvidia Inspector and right-click and select VPU as a graph as well. I'm sure other software has the option to view that as well.

Interesting that a 760 would not experience this. Could it be not using video decode engine for playback because it's old...?

Appreciate your time!

Side note: Curious use case. Some years ago I was planning to get a secondary GPU for non-main monitors but never got around to it. Was it a lot of hassle to set up if you don't mind me asking?

@Pokora

1. VID shows 0%, I guess you are right, it does not fully use the hardware. To old.
2. At first I use one card for one display and the new card as main display card but I have no usage for it.
   It is really easy to set up in Windows.
   If I use the card for displays and for my 3D software it lags as hell during render process so I use the old card for displays and send the workload to the better card, for example.
   Come back to you in few hours.

@Pokora
OK, I change my setup to only one GPU, the RTX 2060.
I got the same result as with the GTX 760, no lag, constant framerate and so forth but no VDI usage playing two Youtube HD videos in two windows on two displays.

Cheers, mib

@mib2berlin
Thanks for letting me know. That is as weird as my stuttering. It should be using video decode for videos... I would even be ok if it wasn't, but videos worked fine.
Wonder what's the difference in setups. Do you have any custom power settings in Windows or anything?

[mib2berlin]

@Pokora
More or less default setup, I disable most apps from autostart and I use only Windows security software.
Can you please post result of chrome://gpu in code tags (</>). I will post mine.

Cheers, mib

Can you share a video link, please?
May different codecs are used.
I checked again with one video HD 60 fps and one 4K 60 fps and no lag.

EDIT:
Just noticed... it wasn't finished loading. The full one gave me a ton of errors. Put it in paste bin because it's too long: https://pastebin.com/W4d6CBTD

Would put it as edit, but got flagged as spam for some reason...

@Pokora
Same errors for me, saw it to late but I think it is not relevant for the stuttering.
Your video and the most Youtube and other use VP9 codec.
I am a bit out of ideas, the Graphics Feature Status shows exactly the same settings.
The most difference is I use a much older driver, the 460.79 is on Linux.
On Windows I use 432, I am sorry, if a driver work well for me I don´t change it.
May one of the GPU experts steps by to help, @Gwen-Dragon for example.

It is not related to GPU, it is related to monitors and their refresh rates and also Vivaldi's Hardware Acceleration setting. I posted this issue back in 2019, had extreme stutter on Twitch making it completely unwatchable, never got any update or reply on this. But after a lot of testing I found I could stop this from happening by disabling Vivaldi's Hardware Acceleration. However, Google Chrome even with Hardware Acceleration enabled, did not have this problem, so it was a Vivaldi-only problem.

It is also related to monitor's refresh rates. You did not post monitor specs but I assume they are different brands with different refresh rates? I say this because I found out that when I play the same video on my 60hz monitor, it stutters and lags, but when I drag the window to the 144hz monitor, it immediately stops all the stutters and plays smooth.

I have main monitor at 144hz, 2nd monitor at 144hz, 3rd monitor at 60hz. Somewhere between my post in 2019 and now, they did something, now I don't have the stutters and lags anymore even with HA enabled, but on the 60hz monitor it is very visible the video is still not very smooth. but it is watchable.

My displays are both 60Hz.

I did omit monitors, sorry. I checked different refresh rates though through Nvidia control panel. I have 3 screens: 1080p@60hz, 1440p@144hz and 1440p@165hz.
Tried different sets of settings with the same effect, even when all 3 are set to 60hz. Also, from what you're saying, it seems you had issues with single videos stuttering. I only have problems with 2+ videos and only when they're on different screens. Otherwise, it's 100% fine.
I did check hardware acceleration now as well. It 'helps' - the videos don't really stutter, but I'm dropping frames (even on single videos and dependant on resolution of the viewport, so guess it's unrelated to the other thing).

Hi, can you may check with the latest Chrome?
If it work fine there you can make a bug report to the Vivaldi bug tracker.
I am sure the developer work on a multi display setup and may one can reproduce it.

@mib2berlin As per op, I run the same scenario in the latest chrome and it's 100% fine. When hw acceleration in both, the browsers act exactly the same. With hw on Chrome is smooth while Vivaldi goes haywire.

Any advice on reporting to bug tracker?

I've been seeing this open bug in Nvidia's driver release notes:

 [YouTube]: Video playback stutters while scrolling down the YouTube page. [3129705]

Not sure if it's related of course but just throwing it out there.
