Hey guys, just sharing info as always. Apparently, MS doesnt allow devs to take full control of the CPU, and GPU in the console, and instead only allowed it to be used in certain ways. I guess this is why games dont seem to push boundaries on the platform. While this has changed now, (X-Engine) do you think this is the reason games dont really stand out on 360?? Discuss

Suspicions were first aroused by a tweet by EA Vancouver's Jim Hejl who revealed that addressing the Xenos GPU on 360 involves using the DirectX APIs, which in turn incurs a cost on CPU resources. Hejl later wrote in a further message that he'd written his own API for manual control of the GPU ring, incurring little or no hit to the main CPU.
"Cert(ification) would hate it tho," he added mysteriously.
According to other dev sources, what that actually means in real terms is that circumventing the use of the standard APIs would result in a submitted game not ever making it past Microsoft's strict certification guidelines which state that all GPU calls need to be routed through DirectX. Compare and contrast with PS3 development, where writing your own command buffers and addressing the RSX chip directly through its LibGCM interface is pretty much the standard way of talking to the hardware."
