Hello
I just test a little thing : an object without material is calculated more quickly than an object with simple diffuse material applied.
Could it be possible to make a more simple material without displacement node to speed up the render ?
New material for speed

Even if you don't apply any material to an object, default diffuse material is used. speed mostly depend on material type (specular renders slower) and overall material brightness.HHbomb wrote:Hello

Karba, I do not agree...
I made some tests.
Same scene one with default diffuse (DD) and one without material assigned (NM)
Diffuse : DD=49s / NM=44s
PMC depth 4: DD=54s / NM=50s
PMC depth 12: DD=2mn13 / NM=1mn55
renders are EXACTLY the same for DD and NM (open and compared in photoshop)
so ?

HHbomb, does that 10% really matter?
developers already have a huge list of things to code..
what exactly You want - how to get fastest speed (for test scenes)?

@Glimpse.
For a lot of people, 20% slowdown is enough to go back to 1.2 and cry everywhere in the forum... even if they have net render, displacement,hair and fur,... I thought that 13.57% (yes) speed gain would be a great benefit... And I would like to know why there is a such a time difference.

The more complex material you use the slower render is. (using textures, mixes, emissions, mediums and so on).HHbomb wrote:@Glimpse.

In your case geometry is very simple, that is why you can sense this speed difference. Once you add more stuff to the scene, the speed difference will disappear.
It is very rare when you have very simple diffuse material for the whole scene.
