Hi Stephane,
  This is completely normal.
When you enable the "FPS" (frames per second) indicator, VMD becomes
100% busy trying to redraw the screen as fast as it can, because the
object that implements the FPS display always tells VMD it needs to
be redrawn. This is intentional, and a requirement if we want to know
what the peak framerate for a given molecular scene is...
You'll note a similar behavior when the "Throb" coloring method is used.
