You are welcome.

Did you install the guest additions experimental drivers to support 3D?
What graphics hardware do you use? I have an Nvidia 8800 GTS. I do not
know how well this option works for other hardware. Also, what type of
acceleration are you using for your X driver (check
/var/log/Xorg.0.log). EXA may be required over XAA. At least, some
type of acceleration is needed.
I am new to this option, so that is all I can surmise.
