Hey guys,
I have a weird discrepancy here.

 

I run a R9 270 Crossfire system, 8gigs ram, Quad Core Cpu

I can play battlefield maxed out at FullHd with NO problem. However when I try to play 4K videos in YouTube they stutter. 

 

Any idea how to fix?

 

I have a good connection btw low-ping - 100Mbp/s

Could you tell us what CPU instead of saying 4 core? <_<

Emmh... Maybe consider killing yourself before you talk to me?

 

Pople on this forum though some of them had a brain, turns out, no.

You could have anything from an FX 4300 to an Athlon to an APU...

 

Spoiler

i5 4670k, GTX 970, 12GB 1600, 120GB SSD, 240GB SDD, 1TB HDD, CM Storm Quickfire TK, G502, VG248QE, ATH M40x, Fractal R4

Spoiler

i5 4278U, Intel Iris Graphics, 8GB 1600, 128GB SSD, 2560x1600 IPS display, Mid-2014 Model

Spoiler

All the parts are here, just need to get customized cords to connect the motherboard to the front panel.

Mb/s*

What CPU (telling number of cores is useless...) and What browser?

accually, your right and wrong, Mb/s is megabytes, mbps is megabits, there are 8 bits in a byte

Honestly, no one knows?

You've not provided enough information so it's pretty odd for you to expect somebody to provide a solution to your problem.

 

A good start would be to tell us what debugging you have done and what results you obtained.

Posting relevant information to your set-up will be handy too even if it doesn't seem 100% relevant (sometimes odd issues occur and providing more information is a lot better than providing less).

Needs more v-core

Is it stopping to buffer constantly or is the video loaded and it's stuttering while playing?

sorry, but you're wrong.

Mb/s (or Mbps) is megabits per second.

MB/s (or MBps) is megabytes per second.

it's the B that is case sensitive, not the M

The 8 bits in a byte is still right though

nvm, decobra got it

What @AlwaysFSX stated. Plus, open up GPU-Z and see whether or not you are VRAM limited. The R9-270X has 2GB of VRAM....not 100% sure it will be enough for even 4K YouTube.

Just so you know, when you Crossfire (or SLI) the VRAM on you graphics cards DO NOT stack. 2GB R9-270X + 2GB R9-270X =/= 4GB.

Actually, a 4K video on a 1080p display would look better than a standard 1080p video.

This is how it looks when I play uncompressed 4k in youtube. As you can see the clip is fully buffered.

I watched 4k with a 1 GB 7770 just fine.

Go through your drivers control panel and remove ALL video enhancement crap.

 

Give that a shot. No doubt a glitch when processing is being done by your GPU to make content look nicer.

Hmm...interesting...

Regardless, check the GPU usage and temperature with GPU-Z.

I have a good connection btw low-ping - 100Mbp/s

 

Are you connecting the GPU to the Monitor via Display Port or HDMI?

I went to to AMD CCC - Disabled all enhancements under Video/Quality. No improvement after reboot. Tried disabling CrossFire as well. No improvement.

 

Hmm...interesting...

Regardless, check the GPU usage and temperature with GPU-Z.

 

This is while playing THIS at 4K. GPU load kept jumping between 0% and 100% depending on whether it's stuttering or playing.

Your CPU is too slow for 4k, simply put. I can almost guarantee it without even knowing what CPU..

 

 

And/or you need to switch to html5 encoding on youtube, normal flash is worse on the hardware. https://www.youtube.com/html5 enable it (only works on chrome/chromium-based browsers atm, and maybe Opera)

Re-install/repair your codecs package to view movies with...?

Maybe a codec issue, even tho youtube probably doesnt use them.... and uses AMD/Nvidia decoders on the GPU.

Who knows..

As I said - I am running 4770k, so it's obviously not that. Read the thread before posting please?

Altho wouldn't hurt to check that HTML5 player to see if it still happens.

 

I'd remove some drivers and re-install them, motherboard chipset and gpu.,... not that it isnt powerful enough like you said, thats the point, maybe bad drivers causing problems.

Bit of a weird issue innit.
