Thanks Dwarf, I think the stuff I am missing is the 3D vision stuff, that shouldn't affect PhysX should it?
I am inclined to think PhysX is installed because FluidMark works smoothly, tells me I have it installed and gives me a score for it. But why is the other stuff (Gpu-z, Cryostasis) telling me it isn't installed?
I have to leave the PC for a bit now so I will check back later, thanks for helping.
