They’re using PSGL (Sonys extension of OpenGL) and LibGCM again (Nope NOT DX11.1!). I’m sure there some major optimization differences going to X86 and funneling the code through the 8 core processor and a standard video card; but the API should be pretty much the same as last Gen (next gen shaders non-withstanding of cource).
I was really amazed that QD apparently not only made the Sorcerer demo with PS3 dev tools, but that they apparently hadn’t really optimized it at all either. Granted, it was small with not nearly the same number of systems a game would be running, but it was still very impressive.
QD also has a history of putting out tech Demo’s and then one upping it with their game releases (The Casting / Kara). It’s becoming pretty clear that the PS4’s will show us some serious sh*t as Dev’s get down to the metal and get better Dev tools.
