Hey there, on my laptop I have a intel hd4600 gpu and a nvidia gt750M gpu.
The nvidia gpu is off ny default and only enabled through optirun/primus as bumblebee is installed.
Does it make any sense performance wise to run "optirun virtualbox" and then boot the virtualbox gues OS from the virtualbox gui?
Thanks !

You would have to check yourself. I think that VirtualBox support 3D acceleration but that's depend of the host and guest OS. I think it might be if you use 3D apps in the guest OS and if 3D acceleration works correctly.

I want to run photoshop in virtualbox with windows so 3d acceleration and more gpu power makes sense.
I just wasbt sure if the guest would use the nvidia gpu even wuth "optirun virtualbox".

The guest does not directly use your graphic card. The guest uses the virtualbox virtual graphic card and virtualbox in turn use your hardware graphic card. Because virtualbox is able to handle 3D, it might well make sense to run it with optirun. However, I know that all of this is not perfect, so I am not sure that in the end there won't be a kind of bottleneck that make this optirun useless.

Hmm I wanted to try this out by running a benchmark in the guest os with and without optirun but it seems like directx as well as opengl aren't working in windows 8.1 as guest os?

I assume this is because the emulated Virtual Box GPU (which is used by the guest OS, not the one VB is using) cannot handle DX.

You will have to investigate the situation further. I know that VB handle some of the 3D acceleration but has limitation. I don't remember what are exactly these limitations.
