At GDC today, AMD announced a suite of tools for developing handheld gaming content for the company's next-generation mobile graphics parts. The suite includes Rendermonkey 1.7, a shader tool that will let game developers write graphics code for a range of devices that support the OpenVG 1.0, OpenGL 2.0, and Unified Shader Architecture technologies. ATI's Unified Shader Architecture in particular is one of the main selling points of the Xbox 360, and AMD will offer support for unified shaders on its next generation of mobile parts.
