i was addressing why you're not seeing the problem.i just hope you understand that you're not seeing the issue because you don't have a 980TI running physX. trying to use a 980TI for physX is the whole issue w/drivers. or it made the PITA process i went through grabbing my 570 to show you completely pointless. :banana: wrestling water cooling tube out of the way, looking for and fumbling around to add 2 more pci-e power cables, uninstalling/reinstalling drivers . . . oy yeh!
