I've researched this a bit, however all the information is from previous years and I'm not sure if it applies now. Basically, I have an ATI 4770 and a NVidia NVS 290 and am wondering if it is possible to run PhysX on the NVidia card while having the ATI card still being the main card. (Both cards work without PhysX in the system, powering a total of 3 displays)
I read somewhere that the 257.15 drivers from NVidia allow you to use an ATI card in the same system. Can anyone confirm/deny this?
