Graphics cards in Windows 8 and DirectX 11.1: more efficient with better performance
 

The most important improvements are primarily in the areas of 2D graphics and energy consumption. If you mainly use your PC for 3D graphics and don't care much about energy usage, you probably wonder whether there is any relevant innovation in that area. And the answer is no, unfortunately. You do get native support for 3D displays in DirectX 11.1, so developers no longer have to rely on parties such as Nvidia 3D Vision and Tridef and instead can realise this directly within DirectX. In theory this will create a unified standard for 3D displays, which should benefit video game developers. Hopefully it will make the 3D implementation more bug- and hassle-free as well, with less tweaking required on the part of gamers.
