VBox 3d acceleration question

Hi guys! Just a little question! I’ve never got if, after enabling the 3d acceleration in virtualbox and installing the guest additions in safe mode, you still need to install the original drivers (catalyst in my case). Do know that by chance?
Thanks in advance!

Install Catalyst on the host and enable 3D acceleration in the extended display features of the virtual machine. Don’t know if it works but that’s the way to do it.
