Afaic, the initial release of the nVidia variant of the Aegia drivers was merely a recompile of the existing source.
They happened to use the gpu, they could equally have used the cpu, and what it looks like they`re point towards was a selector for the user to use whatever they chose.
The code must be either that good, or that well structured, that they were capable of adapting it in whichever fashion they wanted. This could be cos it was perhaps dev`d as a cross platform or simply x86 for giggles and final compile for the pci physx cards.
Either way, it was obviously easy for nVidia to cope with and manipulate to an extent. I feel they automatically discounted the cpu calculator in preference to gpu/physx-pci-card as the gains are that much greater.
Get some gaming companies rolled in tbh !!
