Rather, programs that are run on a Windows XP system with DirectX 10 hardware simply resort to the DirectX 9.0c code path, the latest available for Windows XP computers. [ 35 ] Changes for DirectX 10 were extensive.
DirectX 9.0 introduced Shader Model 2.0, which offered one of the necessary components to enable rendering of high-dynamic-range images: lighting precision was not limited to just 8-bits. Although 8-bits was the minimum in applications, programmers could choose up to a maximum of 24 bits for lighting precision.
Shader Model 2.0a — GeForce FX/PCX-optimized model, DirectX 9.0a; Shader Model 2.0b — Radeon X700–X850 shader model, DirectX 9.0b; Shader Model 3.0 — Radeon X1000 and GeForce 6, DirectX 9.0c; Shader Model 4.0 — Radeon HD 2000 and GeForce 8, DirectX 10; Shader Model 4.1 — Radeon HD 3000 and GeForce 200, DirectX 10.1
GeForce FX 5200. GeForce FX is an architecture designed with DirectX 7, 8 and 9 software in mind. Its performance for DirectX 7 and 8 was generally equal to ATI's competing products with the mainstream versions of the chips, and somewhat faster in the case of the 5900 and 5950 models, but it is much less competitive across the entire range for software that primarily uses DirectX 9 features.
The R520 is the foundation for a line of DirectX 9.0c and OpenGL 2.0 3D accelerator X1000 video cards. It is ATI's first major architectural overhaul since the R300 and is highly optimized for Shader Model 3.0. The Radeon X1000 series using the core was introduced on October 5, 2005, and competed primarily against Nvidia's GeForce 7 series.

The D3DX10 utility library for Direct3D 10 was similar to the D3DX for Direct3D 9 in functionality, and included the same D3DXMath library and Block Compression (BC1-BC5) software codecs. The key differences were that Effects for Direct3D 10 was made an OS component, the HLSL compiler was moved to a distinct D3DCompile DLL, and the texture ...
