Yeah. I have tried to install guest addition twice to test with 3D support 
and without 3D support. And both cases are the same result. No effect appears.

And FreeBSD VirtualBox looks like not to support 3D feature yet.

How did you setup your xorg.conf? or nvidia-settings??

I don't know how to setup to use EXA instead of XAA. 
The 'Option "AccelMethod" "EXA"' are affected for intel and radeon driver, 
not for nvidia.
