I do not know exactly why the processing is taking 0.7 FPS. I Tried em 2 diferrent GPUs, the first was a Radeon AMD 520 (2GB) , it is not so good, so I was not surprised. But when I tried in a AMD 570 4GB (what is better than my GPU) the result was the SAME. Did not presented any error. I belive maybe it just works in NVIDIA's GPU.
