Direct2D renders opaque, transparent, aliased and anti-aliased primitives. Modern UIs often make use of transparency and animation. Direct2D makes it easier to create a modern UI because it has strict guarantees on how it accepts and renders transparent content, and all of its primitives are rendered using hardware acceleration. Direct2D is not a pure superset of GDI: primitives that would have been unreasonably slow when implemented on a GPU aren't present in Direct2D. Because Direct2D is built with this emphasis on 3D acceleration it is also easy to use with Direct3D.

The most important difference between Direct2D and GDI hardware acceleration is the underlying technology that drives them. Direct2D is layered on top Direct3D and GDI has its own driver model, the GDI Device Driver Interface (DDI), which corresponds to the GDI primitives. The Direct3D driver model corresponds to what the 3D rendering hardware in a GPU renders. When the GDI DDI was first defined, most display acceleration hardware targeted the GDI primitives. Over time, more and more emphasis was placed on 3D game acceleration and less on application acceleration. As a consequence the BitBlt API was hardware accelerated and most other GDI operations were not.

Technically, Oracle VM VirtualBox implements 3D acceleration by installing an additional hardware 3D driver inside the guest when the Guest Additions are installed. This driver acts as a hardware 3D driver and reports to the guest operating system that the virtual hardware is capable of 3D hardware acceleration. When an application in the guest then requests hardware acceleration through the OpenGL or Direct3D programming interfaces, these are sent to the host through a special communication tunnel implemented by Oracle VM VirtualBox. The host then performs the requested 3D operation using the host's programming interfaces.

Hardware manufacturers have to write drivers for and test each individual piece of hardware to make them DirectX compatible. Some hardware devices only have DirectX compatible drivers (in other words, one must install DirectX in order to use that hardware). Early versions of DirectX included an up-to-date library of all of the DirectX compatible drivers currently available. This practice was stopped however, in favor of the web-based Windows Update driver-update system, which allowed users to download only the drivers relevant to their hardware, rather than the entire library. 2b1af7f3a8
