- My nvidia 460M doesn't support nvenc and in fact trying to render it
makes a mistake (same errors as Pierre).

- F_Mandelbrot does not work:
PluginFVClient::activate() F_mandelbrot
  err: Function not implemented
PluginFVClient::process_buffer() F_mandelbrot
  err: Operation not permitted
I remember several months ago, when I tried it out, it worked properly.

- I don't know N_body.

PS: Damn! Just as I was moving to an AMD GPU for my future PC,
increase support for expensive Nvidia.  :-)
