First monitor lags when something is moving on second monitor

[4pablo124]

So this is what happens. I have my main monitor overclocked from 60hz to 70hz, and my second one is a small tv screen at 60hz, both monitors run at 1920x1080. The main monitor is connected to my R9 270x via HDMI and the second monitor to the integrated graphics via VGA.

At a normal use everything works fine, not lag o stutter at all. I can play games fine and watch video and streaming. but if I put a video online or streaming or even a video in VLC in the second monitor while I do something in the main one, everything is laggy.

I can't play games while watching a anything because of this. Watching the steam fps counter, I feel like the fps aren't decreasing but even though I can feel the stutter or lag.

I tried setting the main monitor at the stock 60hz, but nothing changes. If I play the video but minimize the window everything come back to normal, but there's still a little bit of lag, isn't until I stop the video when everything is the way it should be.

My specs are:
R9 270x 2gb
8gb ram
A10 7700k
Urano VX 750
F2A88X-D3H
SSD Samsung 850 EVO
Win 10 64bits

Thanks in advance for any help.

how is your 8 gig of RAM arranged? One 8 gig stick or two by four? and how fast? It sounds like your system memory is getting bottle necked trying feed the CPU and GPU of the APU along with the discrete GPU.

The preference in my opinion is to try and run both monitors off the discrete card.

It could also be that the video you're watching is using the CPU to render the stream instead of using GPU hardware assist.

I have 2x 4gb sticks and they 1600hz I think

I followed your advice by running both monitor off the gpu and I see an improvement in the desktop. Now I can actually move windows and scroll a web pages perfectly, so thanks for that.
But for games is still happening, I tried with games that I can run at 60 hz no problem, like rocket league, counter strike and minecraft. It's better than before but still feeling the stutter.

It could also be that the video you're watching is using the CPU to render the stream instead of using GPU hardware assist.

So if it's the cpu rendering the video, how can I solve this, upgrading the cpu?

While you are gaming, do you see your CPU pegged to 100% in the task manager? Because if so, there simply may not be enough CPU cycles to serve all the requests.

Also, try this, in your BIOS go to the Peripherals TAB, select GFX Configuration and under the the option "Integrated Graphics" select "Disable" and save. Basically your discrete card is so much better than your integrated graphics there is nothing to gain leaving it on right now.

If it's your CPU that is causing a bottleneck an upgrade is possible, but let's see if we can sort out what the problem is before you make a decision.

Ok, so I disabled the integrated graphics.

Also I run a little test to see the cpu usage and with a few tabs opened (included the youtube video paused) the cpu is about 5% but immediately after hitting play on the video it goes up and stays around 60/80% even sometimes reaching 90%. That's almost more than when I'm playing without any video, that it's a constant 70/80% (depending on the game) never going up than 85%. As you can assume, when I go both It's just 100% and everything start lagging.

I know my cpu isn't very powerful but 60/80% even 90% sometimes just for a few tabs and one video. Is that normal?

that seems excessive, what browser, what extensions, what video site? If it's adult don't post it. Basically it's not using GPU assisted rendering for whatever you're seeing there.

Also make sure your video driver is up to date of course. Other things that come to mind, is your CPU staying at a high frequency while the video is on? IF the CPU is throttling because of say inadequate cooling then it will look way out of whack.

Basically an HTML 5 youtube video should be around 5-10% max CPU if it's running at it's high frequency.

Update: Apparently the way chrome tries to establish and send video with VP9 compression is very CPU intensive... try watching YouTube in Edge or IE as a test and see if the problem goes away.

I'm using Chrome 64 Bits (It didn't work well before in the 32 bit client either).

This are my extensions:
Alientube for Youtube (It changes the youtube comment for reddit, tried disabling it and it did nothing)
BetterTTV (Add options to twitch, same as before)
Enhanced Steam
Reddit Enhancement Suite
SmoothScroll
Ublock Origin

The sites are usually youtube and twitch. I watch videos in youtube at 1080p 60fps max. (at 1440p it start lagging just by watching the video) and in twitch at source without problems. If I lower the resolution it lowers the cpu usage as well, but at 144p (unwatchable) it's still at 20-30% what I think it's still pretty high considering the resolution.

Everything is up to date. The frequency while playing the video at any resolution is a constant 3,64 hz except in 144p that sometimes goes up and down a bit but very close to the max. And for cooling I have cooler master hyper 212 evo that I forgot to mention earlier.

Around 1 or 2 years ago I tried to overclock the cpu and gpu, but I didn't achieve much so prefered to leave it at the stock speed. Maybe I damaged the cpu in this moment? I don't notice any problems except for this that we're talking about.

Thanks for posting that though. I think the problem is YouTube VP9 acceleration function and how hard it is on a processor.

Install this add on , restart Chrome and test it

Well... trying edge and ie wasn't very succesful, extremely worse in fact:

And the video looks like this:

This happens in both Edge an IE. Tried firefox and it was 95% practically all the time but the image was clear like chrome.
Ironically Chrome appears to work the best.

 

[Mark RM]

well try the add in I suggested above , just maybe that's the key.

 

[4pablo124]

Wow thanks, it drop to 20-40% in 1080p 60fps with the extension. Still lags in-game but I think that it's just my cpu not being powerful enough.
If I put the video at 480p I can play fine.

I was planning on upgrading my rig in the not-too-far future, so I think this is a reason more to add :]

Again, thank you very much for the help. You have been awesome :]

 

[Mark RM]

Yeah it took a while to narrow down but once we got there... bingo. You are quite welcome.

An i3, your existing RAM and existing video card would be a hell of an improvement in gaming if funds are tight but for sure that APU you have wasn't aimed at intense multitasking like you are doing (gaming plus something else).

I think we've done all we can do with what you have. Happy gaming.
