PSGL explained

PSGL is a rendering API available additionally to GCM and OpenGL for Sony's PlayStation 3. PSGL is based on OpenGL ES^[1] and Nvidia's CG. A previous version of PSGL was available for the PlayStation 2 but was largely unused.

PSGL was meant to be a foundation for the future, beyond the PlayStation 3, but for the PlayStation 4 Sony introduced GNM and GNMX and also their custom shading language, PlayStation Shader Language (PSSL).^[2]
