Ryzen 3200G HTPC YouTube 4k60 and 1080p60 dropped frames

[Niels_at_home]

Hi there!

I'm having some unexpected issues with my new HTPC build:

 

System specs:

- Ryzen 3200G stock clocks, seems to boost fine to near 4ghz depending on load

- AsRock B450 Fatal1ty Gaming-ITX/ac

- 2x8GB Corsair Vengeance LPX 3200 running at 3200

- Noctua NH L12S cooler, temps are low

- Kingston A2000 M.2 250GB

- SF450 corsair platinum PSU

- Win10 64, up to date

- AMD drivers, latest ones and also ones from AsRock site, and also with whatever Windows installed by itself

- 43" LGUD79 monitor / tv

- Running 4k60hz over DisplayPort

 

Issues

I get lots of (10+%) dropped frames on  Youtube with 4k60 content and even a few lost frames with 1080p60 content, when I run the desktop at the actual 4k resolution.

When I change the desktop resolution to 1080p, all 4k and 1080p content plays smooth. I realize the 4K content is only rendering 1080p in this case.

 

I get this with Firefox and Chrome.

My internet connection is fine (100mbit fibre) and it seems to have plenty of buffer.

 

With 4k60 content, Task Manager shows peaks of 85% GPU utilization when hardware acceleration is enabled in the browser, never above this. CPU utilization is low

Without hardware acceleration, CPU load is pretty much 100% and the experience even worse.

With 1080p60 content, the GPU load is much lower, perhaps 60% and I still get a few dropped frames and clear stutters as a result.

 

Task manager doesn't seem to report many differences between running the desktop res at 4k or 1080p, yet at 4k it isn't smooth and at 1080p it is..

 

Did I expect too much from the 3200G? Anything I should check? It seems it just can't draw the screen fast enough at 4k to keep up or something odd. I am late to the 4K party but my plan was to enter it more smoothly..

Maybe something better than task manager to monitor stuff with.  You’ll be wanting to look at cpu and gpu performance simultaneously.  Should be something decent and free out there.  No idea what it would be though.

Do you have other HDMI cables to try - maybe an older cheaper HDMI cable causing bandwidth issues?

 

My only experience with 4k with an APU is an i3 6100t with onboard GPU.  It was atrocious, didn't like it at all.  Felt laggy but I never FPS checked it.  I hook up my FX 8350 with HD 7850 GPU and browser, video etc lag is completely gone.

Point.  Diddnt see the HDMI.  HDMI doesn’t have versions like other data standards.  It’s actually illegal to promote a version.  The older cables though sometimes don’t work as well.  Cable manufacturers hate the lack of version thing and try to get around it. Newer ones often say “8k”.  All that means though is the cable wiring is of ever so lightly higher quality.  An older cable might be just as good as a new one, but it also might not.

I've had DP cable issues in the past with 144hz  1440p monitors, but that never resulted in dropped frames. It would only allow 60hz or 1080p as it sensed a lack of bandwidth.

I use the supplied DP cable with the LG 43" monitor and it allows 4k60 all day. Dropped frames because of the cable would only seemingly be possible if it lost sync or connection briefly which I really don't think is the case. If that happens you'd see a black screen briefly or spikes in cpu / gpu use I would say..

I never had any issues watching 4k content on my 2200G so I kinda doubt that is the issue.

Hey Mark, did you also have the desktop resolution at 4k? I see a performance difference watching 4k in 1080p desktop or 4k desktop.

Hi, no, sorry I actually didn't.   Only have a 1080p screen, but I already thought about that as a possible reason and that it may make a difference, so it's maybe the CPU/iGPU after all,  even though that's kinda unlikely as that doesn't seem to be a widespread issue.  Hmm. 

 

Edit: I looked it up,  it actually seems to be an issue, there are  a couple of reddit threads, etc, I didn't really see any *reviews* mentioning this issue however.

To those interested.. I 'fixed it' by using Edge instead of Chrome or FireFox. Somehow gpu usage is a bit lower and it just runs silky smooth with zero dropped frames there.

 

Now it is weird, somehow Edge does different hardware detection or something. On my desktop GTX 970 it doesn't even give me a 4k option on videos, probably because the hardware decoding is missing from this older card. Yet in FF / Chrome it is available.. So something seems to be handled differently on Edge.

 

And to my surprise, you can even get an ad blocker for Edge?! So MS has the go to browser now?! I need to sit down..

Hi!
I have the same problem with YouTube on 3200G in browsers FF and Yandex.browser even in 720p resolution.
My system: Ryzen 3 3200G
Gigabyte B450M S2H
Patriot DDR4 8GB 2666MHz
SP Velox V70 120GB
Cheiftec SFX-350BS
  I tried different versions of the AMD videodriver and increased the frequency of RAM, but this does not change anything, the frames are dropped again.
On my old system (fx6300 / 8GB ddr3 / hd6850) there were never any problems in playing YouTube of any resolution, everything worked perfectly.
I am very surprised that the new technological APU has problems with YouTube

Yeah.  Google has released a bunch of free web development kits that are supposed to be browser agnostic but somehow subtly aren't.  Microsoft did this back in the day too though they were less subtle about it and got caught.  It also happens to safari.  Pages break that didn’t used to, and somehow google brand products are the only ones that just work.  
 

anyone remember c#?  The “version” of c that just didn’t quite work on anything but Microsoft stuff?  I understand it’s a bit better now but there were multiple lawsuits.

 

to me this looks like SSDD
