water reflections with path tracer

[Kevin F]

Can somebody please explain how to use the new water shader? Why are reflections in perfectly still water blurred?
Great new features in the latest release, but explainations of how to use them would be a good idea.

You have to decrease min highlight spread to less than 0.005 for less blur, or to zero to get perfectly hard reflections.

Ah! Thank you maestro!
