Horrible video lagging/stuttering

[Kepke]

Hey,

for a few weeks now i'm experiencing horrible lagging/stuttering with video playback using the vivaldi browser. Be it youtube or other websites, any and all videos just stutter like they are runing at 12fps. I've tried everything i can, from updating windows, drivers and trying power settings up to reinstalling the damn browser, without any success.

I've tried chrome just to see if it's maybe a issue with my pc, but videos run smoth and without any stuttering, so it has to be a vivaldi thing. I really don't want to go back to firefox and i'll be damned if i have to use chrome (i don't like how it makes my fans ramp up when i switch tabs). Ofc, i have tried video playback with AV, extensions and other background software dissabled. No change.

The issue didn't come up after an update, in fact, when it started, i haven't updated anything at that time.

Note: using two vivaldi windows, if i have a yt video runinging in one and scroll in the other, the yt video will lag like it's a 5fps slideshow! Same if i try having two video play, both just massacre each other. Is bad, pls send help. Audio has no issues btw, even if the video lags.

PLaying games while watching yt doesn't affect the game at all and the browser behaves the same, it laggs and stutters "like usual", however, sometimes my cursor lags on the desktop, when i have vivaldi open with a video runing.

Here's the vivaldi//:gpu stuff:

@Kepke First, when posting a lot of text like that use code blocks!

Like this, see?
    Makes your wall of text easier to parse...

You have disabled hardware acceleration: "Gpu compositing has been disabled, either via blacklist, about:flags or the command line. The browser will fall back to software compositing and hardware acceleration will be unavailable."

The --ignore-gpu-blacklist flag has no function when you disable H/W acceleration.

Check your settings under Webpages > Use hardware acceleration, make sure it's checked. Restart the browser if changed.
Go to URL vivaldi://flags and set all you've changed to default.

@Kepke
Hi, another user report YT problems with RTX 2070 so it is may a driver/Vivaldi problem.
Quick view looks like Vivaldi does not use hardware acceleration at all, all is working in software emulation.
Do you have hardware acceleration enabled in Vivaldi settings > webpages?
Please edit your post and set "GPU stuff" in </> it is very hard to read.
I use GTX 760 for display but I have a RTX 2060 for 3D render stuff, I can change tomorrow and check RTX 2060 for display on Windows.

Cheers, mib

Hey,

thanks for the replies. I couldn't find hardware acceleration in flags, but thanks to master @Pathsducks i found it in settings. Let's see how it turns out.

@Pathduck said in Horrible video lagging/stuttering:

NVIDIA GeForce RTX 2080 Ti - Nice card mate, you must be full of $$$ amirite?

Got mine on release, so the 1200$ don't hurt me to much like it hurt the poor souls that got a 2000 series days before 3000 rolled in. lol also paying in instalment ftw.

Edit: tried to edit my first post, but pc said no. Flagged as spam?

@Kepke
Hi, you need more votes/reputation to edit posts.
At moment only moderators can.

Cheers, mib
EDIT: Test with my RTX 2060 as display card and no problem with 4K 60 Fps in one window and forum in other Vivaldi window.

Thanks for help, H/W acceleration was the solution. Now it's all butter smooth again! Just don't know why it suddenly dissabled H/W acceleration?
