i'm using windows 8.1 on my ubuntu 14.04
i want to benchmark my guest machine and ran webgl content on my chrome browser.
but this benchmark doesnt work since my browser doesnt support webgl.
it seems virtualbox driver doesn't support webgl feature.
is there any way to enable webgl feature on my guest machine?
why my Guest os cannot play webgl content?

Re: why my Guest os cannot play webgl content?
Not sure what you mean. results from IE11, Windows 8.1 guest. VideoBox driver works for me.
Google Chrome
Not all WebGL content will play. Depends on the version of OpenGL. Also I couldn't get Firefox to play WebGL content.

Re: why my Guest os cannot play webgl content?
oh i mean, webgl support using h/w acceleration
currently, guest machine runs webgl contents with s/w renderging, it is very slow and consumes cpu resources
which is not very efficient and effective.
but i want my gpu plays webgl contents.

Well of course you need VT-x enabled and the guest additions installed to enable 3D acceleration.
you can't use your GPU in a virtual machine.

But.....
By using guest addition, VM can use hw acceleration(handle directx or opengl api)
why not webgl??

Re: why my Guest os cannot play webgl content?
webgl is a browser API, not a PC technology. Browsers which implement it will call down to an underlying OpenGL or DirectX API in the OS.

Re: why my Guest os cannot play webgl content?
AFAIK WebGL requires more advanced OpenGL 3.x technology.
VirtualBox only supports OpenGL 2.1 in guest OSes. So even if host OS supports OpenGL 4, guest will only "see" OpenGL 2.1.

Re: why my Guest os cannot play webgl content?
I doubt that is a requirement - I imagine one could implement the browser api over a DirectX underlying layer - but it's probably true in practice.

Re: why my Guest os cannot play webgl content?
FWIW, I've played some WebGL content in some guests. Sometimes only in Google Chrome, some also in Firefox. I also had a WebGL demo crash Firefox running in a Linux host although it would play others. WebGL results are very inconsistent.
