Microsoft DirectX is a group of technologies designed to make Windows-based computers an ideal platform for running and displaying applications rich in multimedia elements such as full-color graphics, video, 3D animation, and rich audio. DirectX 9. Update: SDK download listing. A link would be nice. Is this a release or a public beta? Have you installed it yet?
Any performance improvements? I now fixed it, just click on the second link on this story to download the setup program of DX9. Not much seems to have changed externally. There is a new DirectX logo that resembles the X-Box logo. Also, the dxdiag. For all the other, they will only used a compatibility mode in DX9 against the oldest. Providing hardware acceleration of new features without actually having the hardware present would be a neat trick.
Xavier is right, too. Who said compatibility mode used any sort of hardware accelleration. The calls are sent to the CPU and handled there. Slow, yes, but it is compatibility. That means, he said, that by then ATI will not have the only card that supports DX9 and that the driver support for this release is very very minimal.
Further, there does not yet seem to be a public SDK. So, at least, it will be a good reason to get DX9. Again, only if you have a DX capable video card e. For anyone else the release of DX9 is pretty much a non-event. I find it very irresponsible of OSNews to run a misleading story announcing that is is released.

For games that are on both Xbox and PC, it makes sense to use DirectX 9 on both versions to minimise the work required rather than maintain two separate graphics engines. For example, on Xbox it is simple to read a depth buffer from a shader, but on PC with DirectX 9, you have to resort to either writing depth to a second R32 format texture which is slow or using driver hacks such as the INTZ texture format and then deal with different graphics cards separately.
New driver model - Due to the change in driver model for DirectX 10, all the graphics card manufacturers had to write new drivers to support the new system. This resulted in bugs and performance issues in DirectX 10 games at the time. This is entirely understandable as any new complicated piece of technology is bound to have teething issues and the issues have since been solved , but it feels as though DirectX 10 gained a perhaps undeserved? When Windows 7 was released, the new version of DirectX was numbered 11, rather than The ability to write long HLSL shaders meant that games suddenly had the ability to use more sophisticated lighting models, more varied materials and post-processing — all with some quite straightforward programming and a good understanding of maths.
There are many DirectX 9 games that simply would not have been visually possible beforehand ignoring OpenGL for the purposes of this post! For this reason, DirectX 9 is still visually good enough for modern games.
