The fixed function pipeline is implemented as a shader-based pipeline on modern hardware, so it doesn't mean the CPU will be doing all ofthe work.

If you've created your device with the D3DCREATE_HARDWARE_VERTEX_PROCESSING flag (I think that's the right name for it) then the GPU will do all vertex transformations and lighting in hardware. Otherwise it'll be done in software (on the CPU).
