Extreme lag and stutter on one of two monitors

[Feudal]

I have a 1080p monitor and a 4k monitor. The 1080p works fine, Firefox and Discord scroll smoothly and have no issue, fullscreen Youtube plays without issue. The 4k monitor on the other hand, it's a pain just to scroll through these forums. Youtube videos have extreme stutter when fullscreened, about 4 frames a second, and input lag is even more if it decides to read the input at all. I haven't had issues with the two very basic games I've installed so far (EU4 and Minecraft) but I'm planning on installing some of my more demanding games later.

I'll copy/paste important system specs from inxi -Fzx to tell the rest of the story.

I switched to Linux just yesterday because of how badly Window's rot destroyed my wifi. Went from 300Megabit to 10-0Megabit. I have very little a clue what I'm doing and just searching through forums for all my problems. I could not find a solution for this problem. Also, sorry if I should be posting this in NVidia Graphics Cards, I'm not sure if this even has to do with my GPU directly.

I managed to turn off hardware acceleration on Steam, that fixes some of the issue with Steam specifically, but I can't figure out how to do the same with Firefox and Youtube. I've already turned off hardware acceleration before and it did nothing. Smooth scrolling is off too and it's still not responsive.

I don't want to stop you from using Linux, but did you check that you don't just experience the internet problems many people got due to the pandemic?

Try to watch twitch.tv or youtube using the chromium browser instead of firefox (chromium is not chrome).

I had lots of problems with fps/stutters/input delays while watching these sites and playin games using proton. I "fixed" it changing the browser i use while playing (my internet connection is ok; my CPU is a ryzen 3900x and GPU Nvidia RTX 2070)

PS: i love Firefox

...and yeah, this "fix" aint pretty :-(

To reduce lags and stutters with Debian 10 I have
1) created an optimized kernel (I notice yours is generic) This is the biggest improvement.
2) run the steam process with lowered priority

These are pretty standard things to do so there is lots of help on how to do.

Seems like a graphics driver issue. I don't use nVidia; however, you can verify by launching a terminal and enter 'glxgears'. If you see spinning gears, good! Then wait for the fps count to start appearing. The fps should be equal or greater than your monitor refresh rate. If it is lower, then your system might not be utilizing the optimal graphics driver.

Shouldn't about every integrated graphics be able to do this in 60 FPS?

I would be interested in such a kernel for future use. I do want to use Linux.

I also noticed that it was an ISP issue but only some of the time. Most of it was windows and it was fixed going to Linux. That beind said a lot of things are broken or just don't work right which mostly means I use computers for the one thing Linux isn't great at which is gaming. Drivers don't work, hardware acceleration doesn't work, games I play run like garbage and have massive graphical issues. Hell even EU4 had issues which is just amazing.

I plan on switching back, I gave this OS a day of my time and found the faults. It isn't optimised for what I do with computers. I can fix windows rot by reinstalling anyways. I'll admit I only switched to Linux because I happened to have a spare Mint 19.1 on a flash drive and no windows ISO lol. Now that I have internet nothing can stop me from going back.

I enjoyed my time with Linux though! That one day actually taught me a lot! It was sort of fun too being the biggest nerd in a discord channel and figuring out the 2 hour, 6 step terminal process to launch a minecraft server.

If the problem has nothing to do with missing drivers (check that first), it must be something hardware related, probably a lack of cooling.

I play games on my Linux System (Ubuntu) all the time in 4k.

I doubt anybody's ISP has real bandwith problems during the pandemic. I know that for sure directly from several ISP. Most people have no idea how to use Wi-Fi and blame the "internet".

So Netflix, YouTube, Azure,... are tuning down for no reason? You really should tell them...! (Yes, I know that's not ISPs. But it's a clear sign of problems of what really is the internet.)

Prophylactic actions! No reason at all to watch streams on 1080p, 60 fps. I think 720p, 30 fps is good enough when dealing with a pandemic stuff... we have lots of services that need internet. And lots of people are "locked in"; they need internet too

[Marlock]

I believe the point @zyro made is that they didn't act preemptively without any sign of trouble... they acted (voluntarily, yes) but already upon seeing clear signs of trouble in some regions, eg due to increase in homeoffice usage of VMs, video and audio calls, etc (as their own recent comunications to clients state)

I am positive that at one point Azure itself became sluggish under the pressure here in my country, as this has been officially informed by my company's IT department (we for example started using it for ~30.000 people overnight, between VPN intermediation, cloud services and VMs neither of which were broadly employed before)

One obvious factor for this is: ocal infrastructure in not-so-fiber-blessed countries was already overloaded before the change in usage patterns.

It doesn't have to be enough of a usage increase to bring down the entire internet. If it can break the pocket a person is in, that person will see the effects.

[NRG-R9T]

you don't seriously believe that marketing ♥♥♥♥♥♥♥♥ of Netflix, Google (Youtube) and Amazon (Prime) plus Disney, that a slightly higher demand for their streaming services will bring down the whole of ISP's networks, right? What we know for sure is their increased costs and ressource capacity challenges for their flatrate-based business models. They don't earn more now while more people than usuall use their services intensively.

Its true that some governments called also for bandwith reduction, but for example the EU are famous already for their ignorance from real expertise and therefore stupid political actionism, plus lobbyism of streaming services and cloud providers. Politicians believe what Google and Netflix say, not what your local (national) ISP says. Ask an ISP if they are at their limit already, after they invested billions into their fibre networks. Seriously. It's a joke!

It is not about believing ; it is a matter of taking some prophylactic actions; bandwidth aint infinite, so, it needs to be managed. If you know more people will use the internet ( #StayInside ), you can lower the quality of the stream, and yet, let people watch your content and use other services.
I dont care about their marketing; and for me, twitch should do the same.
Dont need much to help more people enjoy/use the internet. When things are back on track, they can stream in 4k, 144 frames/second, 3D / holographic ♥♥♥♥ with lasers n pew pew...

The costs of Netflix have risen, while their income mostly stayed unchanged. Streaming Services need a lot of computing on the server side. You see the problem, right? ISPs have seen an increase of about 10% in overall traffic also, but they are well ahead of any overloads. They invested billions into fibre networks in the last 10 years. It's no wonder, they have to plan years in advance and the internet never got any smaller but grows faster and faster since the beginning. It's no rocket science to imagine how well an ISP is prepared, one that is constantly investing in more infrastructure than needed, otherwise they would loose big customers.

Movie Streaming users at the other hand can be fooled easily into believing, that the promised service quality, that they paid for, is mostly unavailable, when they need it the most. They also think their ISP has bandwith problems, when their Wi-Fi-Signal at home gets weaker when they move away from the antennas. It's no joke. Netflix users are fooled into these "prophylactic actions" to save Netflix's cash flow.

I'm finding it slightly funny that you're so easy to distrust Netflix and other streaming service companies (which you should) yet are so easy to trust ISPs (which... erm... well...).

I'm not sure how it goes in your country, but here the big ISPs routinely practice bandwidth overbooking (lend a useful terminology from air companies, not sure what the proper equivalent expression here) and also procrastination of investments in infrastructure upgrades (to the extreme that we still don't have really complete 3G coverage even in urban areas in some cities, while the world is getting ready to adopt 5G).


And here is some numbers to give a sense of the measurable impact in usage patterns (which you may argue won't be enough to cause any issues, but then I'd cycle back to "maybe not in your country"):

“Broadband providers are thus far experiencing a traffic surge between 30% and 50% across their mobile and fixed networks,” said Alfonso Marone, who is head of media strategic advisory at KPMG U.K.: “Where self-isolation policies are at their peak in Europe, the spike in internet traffic has reached as high as 70%, which is indicative of what the traffic surge could look like in other regions in just two to three weeks’ time. The most bandwidth-hungry are the online entertainment applications, especially those in high-definition like 4K movies and TV. For broadband providers, this spike may be seen as more a source of headache.”
