That means, in a business decision, they decided that PhysX was a good fit with their company, to help them earn revenue, so they made the investment. NVidia owns PhysX, outright, they paid BIG money for the entire package. I can't believe how falsely entitled people seem to believe they are these days. No matter Nvidia's intention, can you blame them?

#Do i need nvidia physx system software if i have amd drivers
The Tech Report notes that while this applies to GeForce 186 drivers and beyond, it only really affects people running Windows 7, as Vista's Windows Display Driver Model (WDDM) 1.0 can't run multiple GPUs with different drivers simultaneously - as opposed to Windows 7's WDDM 1.1, which can. A forum post on NGOHQ shows an email explanation from Nvidia's Customer Care, which lists a variety of causes for the decision, including "development expense," "quality assurance," and "business reasons."
