1st main graphic card (for rendering graphics) is connected to the monitor. How about the 2nd card (for physics rendering)? Does it need to connect somehow to a monitor? From my reading, it seems this was the case before GeForce driver 180.xx. But since then, there is no such need. Correct? With 180.xx, does somehow the nVidia GeForce driver (and PhysX driver) will detect and properly setup the 2nd graphic card for PhysX usage?
Can someone describe how this "Multi-card" (terminology used in nVidia PhysX website) setup is connected, hardware-wise?
