today Svyatoslav Lockal send us a great patch which improves Perlin<br>
Noise calculation for Cycles CPU rendering, it's in master now.<br>

Some tests with the BMW scene resulted in a 12-15% render speedup.<br>
<br>
But I was curious to see how this behaves in a more production like<br>
environment, so I checked a file from the Open Movie Caminandes.<br>
The scene I used was 11a_comp.blend (New Hope scene) from Caminandes on<br>
an Ivy Bridge Quad Core (3.4 GHZ) on Linux.<br>
I rendered frame 500, with 1280x720 resolution, otherwise it's unmodified.<br>

Before: 01:06:22h<br>
New: 53:13min<br>
<br>
That is a speedup of about 20% (19.76%), which is a lot. I checked the<br>
node setups and the artists used the Noise Texture almost everywhere. :D<br>
<br>
Just wanted to share this, enjoy!<br>
<br>
Best regards,<br>
