	Since the SDK uses Clutter and 3d effects, the speed of the UI depends greatly on the 3D acceleration speed on the host system. For many popular display adapters (nVidia, ATI) this means that the vendor provided closed source driver is needed for fully utilizing the 3D acceleration provided by the hardware. Using Intel cards, the hardware acceleration should basically work with the available open source drivers, but unfortunately some versions of the driver have been buggy in a way that causes problems for the 3d accelerated applications and thus also the SDK.
