Microsoft DirectX version 10.1 is projected to be the last and final update to the DirectX 10 application programming interface (API), the head of developer relations of ATI, graphics product group of Advanced Micro Devices, recently said. While Microsoft DirectX 9 had several shader models, including versions 2.0, 2.0a, 2.0b and 3.0, the DirectX 10 will exist in two versions, 10.0 and 10.1, said Richard Huddy, worldwide developer relations manager of AMD"s graphics product group at a conference recently.
The DirectX 10.1 is a relatively minor superset of DirectX 10, but it will last for quite a time, unlike the 2.0a or 2.0b versions of shader model 2.0 that were promoted back in 2003 and 2004 by Nvidia and ATI, which did not become popular due to availability of shader model 3.0. If Microsoft does not have plans to develop its DirectX 10 further and will concentrate on the DirectX 11 instead, developers of graphics processing units (GPUs) will not need to add any new functionality to their products and will therefore have to focus on performance, rather than on innovation of functionality.
