And that's the main issue. Devs don't NEED options. That's the whole point of the console space, a closed platform. It's an act of desperation, really. CPU-based physics is like 1962 technology. Really. It's now 2013, 50 years later. That's why I quoted Jen Hsun's questions for entrepreneurs.. it's NOT the right way to do it, and Phys-X running NOW on GPUs proves it. Nvidia must have hired some of AMD's old marketing team.
