AMD has revealed that Microsoft will not be releasing several versions of DirectX this time round, as was the case with DirectX 9, instead it will focus on DirectX 11 after the 10.1 update for DirectX 10 is released. With DirectX 9, Microsoft released major updates a number of times to allow for different shader models (2.0, 2.0a, 2.0b and 3.0). However, Microsoft looks set to encourage graphics companies like ATI and NVIDIA to focus on increasing performance rather than adding more features for the next few years, at least until the launch of DirectX 11. This could potentially pave the way for NVIDIA and ATI to work on multi-GPU graphics cards without the need to keep adding functionality. Microsoft will almost certainly continue to provide minor updates for DirectX, just with no major changes integrated.
