The GMA 950 shares the same architectural weakness as the GMA 900 no hardware geometry processing. Neither basic hardware transform and lighting, nor more advanced vertex shaders are handled in the GMA hardware.

Rendering Tier 0
A rendering tier value of 0 means that there is no graphics hardware acceleration available for the application on the device. At this tier level, developers should assume that all graphics will be rendered by software with no hardware acceleration. This tier's functionality corresponds to a DirectX version that is less than 9.0.
Portanto, para esta placa não há aceleração de hardware, o Direct X pode ser instalado, mas seus recursos não estarão disponíveis.
