Hi,

I have been doing several tests regarding 3D acceleration with windows and linux guest over a linux host during the past weeks.
My setup:
linux host:
Debian with Virtualbox 4.3.14-dfsg-1 and virtualbox-guest-additions-iso 4.3.14-1
and nvidia-glx 304.117-1

I successfully managed to run tulip (search tulip labri on a web search engine (sorry I cannot post a u.r.l. yet due to forum restrictions)) which is a graph renderer using OpenGl on the following guest:
Debian Wheezy with guest additions installed
Windows 7 with guest additions installed

I couldn't achieve this on windows 8.1. Yet it works well on a non-virtualized windows 8.1.

Reading the documentation I haven't seen windows 8.1 as officially supported for 3D acceleration.

3D acceleration with Windows guests requires Windows 2000, Windows XP, Vista or Windows 7. Both OpenGL and Direct3D 8/9 (not with Windows 2000) are supported (experimental).

(virtualbox manual ch04 section 4.4. Hardware-accelerated graphics (sorry I cannot post a web address yet due to forum restrictions…))
What is the current state of support of 3D acceleration regarding windows 8.1?
Are there specific steps to under go in order to make 3D acceleration work well with windows 8.1?
Is there any roadmap planed regarding the support of 3D acceleration on windows 8.1?

Thanks in advance for your feedback.

As the documentation states, experimental. That means, if it works, it works. If it doesn't, it doesn't.

The only steps you can take from your side is to make sure that you have a recent, solid driver for your graphics.

The developers don't really disclose that information, not just on graphics, but on everything.

Thank you for your quick and accurate reply.

Best regards.
