arcticstoat writes "Just a few months after The Khronos Group unveiled the Open GL 3.0 spec last year, AMD has included full support for the new API in its first WHQL driver of 2009 — Catalyst 9.1. OpenGL 3.0 requires DirectX 10-level hardware, such as AMD's Radeon HD series of GPUs. However, unlike Direct3D 10, OpenGL 3.0's features can be enabled on both Windows XP and Vista, as well as Linux and Mac OS, which could be a bonus for game developers looking for a broad base of customers. The Khronos Group claims that OpenGL 3.0 has a 'rough feature parity' with Direct3D 10, and it provides Shader Model 4.0 support, including features such as the Geometry Shader. The Khronos Group also says that the new API will interoperate with the GPGPU API OpenCL, which could allow OpenGL 3.0 to compete with the Compute Shader promised in Microsoft's DirectX 11 API."
