Hi,

In your HDR map the sun is very low so the building around the pool is blocking light from it and you only get light from the sky which gets undersampled because of the sun hot spot.

The whole scene is relatively slow.t

After my experience a render is getting noise-free in less time when firefly rejection is used (but it adds a bit bias IIRC).
Also firefly rejection shouldn't be too expensive if you use the latest 0.9dev-build and keep the value low (like 5).

O.k. jeanphi.

B.Y.O.B: Do You speak about noise not fireflies? That means, firefly rej. is also able to denoise Window glass for example?

Firefly rejection is a mechanism that does not only "remove fireflies", it's not that simple. It is included in the rendering process.
