Although the task is crunched on your GPU, it has to get from the drive to your videocard's memory somehow. Since it can't be done by magic, a part of a CPU is used for this.

That's what is showing. When it says 0.09 CPU, it means 9% of the CPU is used to move data from disk to video memory and back. The actual crunching is done on the GPU.
