Digitimes reports; "Nvidia is expected to announce the world's first DirectX 10-compliant graphics chip, the GeForce 8800 (codenamed G80), in the middle of November, graphics card makers revealed. However, despite the advantage of early launch, demand for the new graphics processing unit (GPU) will depend on penetration rate of the new Windows Vista OS and availability of new PC games supporting DirectX 10, the makers indicated.
The makers expressed the doubt that ATI's next-generation R600 chip, which is also expected to support DirectX 10, may appear in the market before 2007.
Since DirectX 10 is positioned as a Microsoft software Vista-only solution, with presumably no ability to work with previous Windows versions, Nvidia's move to launch the GeForce 8800 in November should rather be considered as a symbolic step, in line with the Windows update, said industry sources. So far, Microsoft only promised that Windows Vista will run DirectX 9.0, allowing to later upgrade it to DirectX 10 via Windows Update, the sources indicated. When Microsoft releases a DirectX 10-capable OS, ATI will perhaps catch up with the competition, the sources added."
