Companies like Sony use in-house custom versions of OpenGL for their API's. They support OpenGL but aren't using it out of the box for their toolset. See: lib

See: libgcm, gnm, gnmx. Although I'm not positive that gnm/gnmx are opengl derivative.

- jblow 12y agoThey are not OpenGL derivative. I don't know why this rumor propagates. Oh wait yes I do, because those of us who know what the APIs look like in detail generally can't say anything about them because of NDAs. Sigh. To be clear: None of the APIs you listed are based on OpenGL. PSGL was an OpenGL implementation, but nobody writing a high-performance game used it because it was too slow and unreliable. The APIs used by almost all shipping games you can think of are substantially lower-level.
