Video Tutorial:

With this effect you can create 100% accurate Planar Reflections on planar surfaces like floors, glass and water. The SpeedRay Reflection setting adds reflections to all other surfaces not assigned a Planar Reflection.  They are less accurate than Planar Reflections, but offer the opportunity to massively improve image quality with little extra render time. Reflective surfaces are automatically improved at the flick of a switch.
