Shortly after the Khronos group announced the OpenGL 4.0, the newest version of the multi-platform graphics API, AMD is out with a preview graphics driver for its ATI Radeon, FireGL, FirePro, and Mobility Radeon graphics accelerators, which includes the OpenGL 4.0 ICD (installable client driver). The driver is available for Windows 7, Windows Vista, Windows XP, and Linux. OpenGL 4.0 is comparable and up to times with Microsoft's DirectX 11 API, it makes use of hardware features such as tessellation on the GPU, per-sample fragment shaders and programmable fragment shader input positions, 64-bit double precision floating point shader operations, etc., and has no restrictions on which later version of Windows it can run on. With OpenGL 4.0 for example, one can expect 3D graphics with the complexity comparable to DirectX 11 on Windows XP.
