youtube really slow in virtualbox 5.1.6-1

Can someone help me with my virtualbox configuration. I installed linux mint on a virtual machine in virtualbox. The same vm works great in windows 10, meaning I can watch 4k video on youtube, vimeo etc.. without issues. When I boot the same machine in Arch, youtube barely works. The video is super choppy and so is the audio. I tried downloading guest additions from virtualbox (VBoxGuestAdditions_5.1.6.iso) and installing it from within linux mint but that didnt help. Same issue. I want to say its something related to my video card but im really not sure. I actually never experienced this issue when using virtualbox on arch in my laptop but im now using my desktop which was recently built and is using a video card. I believe I do have the correct packages installed:

virtualbox 5.1.6-1
virtualbox-ext-oracle 5.1.6-1
virtualbox-host-dkms 5.1.6-1

Im almost positive I am using the correct nvidia drivers:

01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1) (prog-if 00 [VGA controller])
	Subsystem: eVga.com. Corp. Device 3967
	Flags: bus master, fast devsel, latency 0, IRQ 134
	Memory at de000000 (32-bit, non-prefetchable) [size=16M]
	Memory at c0000000 (64-bit, prefetchable) [size=256M]
	Memory at d0000000 (64-bit, prefetchable) [size=32M]
	I/O ports at e000 [size=128]
	[virtual] Expansion ROM at 000c0000 [disabled] [size=128K]
	Capabilities: [60] Power Management version 3
	Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [78] Express Legacy Endpoint, MSI 00
	Capabilities: [100] Virtual Channel
	Capabilities: [258] L1 PM Substates
	Capabilities: [128] Power Budgeting <?>
	Capabilities: [420] Advanced Error Reporting
	Capabilities: [600] Vendor Specific Information: ID=0001 Rev=1 Len=024 <?>
	Capabilities: [900] #19
	Kernel driver in use: nvidia
	Kernel modules: nouveau, nvidia_drm, nvidia

the system has more than enough resources as I mentioned the VM runs great in windows 10. If someone can point me in the right direction it is greatly appreciated. I provide more output if necessary. Just not sure where to start or how to go about it.

Thank you

Re: youtube really slow in virtualbox 5.1.6-1

Either network throughput or the video acceleration isn't carried over by virtualbox.
If a local 4k video plays fine(try eg. youtube-dl) , it's the network. If not, video acceleration isn't provided in virtualbox. Compare the guest video drivers (is the guest system linux?)

Your notbook is likely an intel chip where the opensource driver forwarding via dri3 isn't any problem for virtualbox where it may fall back to a generic VESA driver on the prop. nvidia blob. (Does GL acceleration work in the guest system)?

Re: youtube really slow in virtualbox 5.1.6-1

i installed virtualbox on my laptop today which is also running arch linux xfce and ran into the same issue. So maybe its not something with my video card on my desktop. The arch linux configuration on my laptop is almost identical to my desktop. I never had this issue before on virtualbox but its been a while since i used virtualbox.

I dont think its the network. My speedtest shows about 80/80mbps and I can actually see the video cached on the navigation bar on youtube except the video doesnt play. these issues are on the guest machines btw. Do i install the same video drivers on the guest machine as I have on the host machine? On my desktop I have an nvidia gtx 960 video card and on my laptop i have integrated intel hd 5500 graphics.

is anyone else runnning into this?

Quote from this link :

I found a solution for this a few weeks ago somewhere and it worked for me. I realized the videos don't play on the VM because of the audio settings (and not any video settings).

    Shut down the VM (in my case Ubuntu 16.04.1).
    In VirtualBox, click "Settings".
    Go to the "Audio" section and change the "Audio Controller" from the default to the other available option ("Intel HD Audio" controller was my 2nd option).
    Start the Virtual Machine and see if this work.

... helped me to resolve same youtube-video-freeze problem after all day researching.  I was using  'ICH AC97' VBox driver setting, and when I changed to Intel HD Audio, problem was solved.

Tested on: Arch64_(nvidia970) host + guests: Xubuntu_16.04_32bit, Ubuntu-Mate_16.04_64bit, Arch64; Mint_XFCE_17.3_32bit.
Note: Mint_17 actualy didn't have that problem, and was able to play YT video with 'ICH AC97' VBox driver setting, but with Intel HD Audio, playback was slightly improved. Since Mint is version 17, and have older kernel, 3.19 or similar, can't remember, I think that there is some clue, but that transcends my knowledge...
