Recently I upgraded to 4 Cores CPU and found out render to become much faster
But today when I played with ray tracing etc I found that blender does use only 2 cores
when rendering some parts of image. I have 4 threads settings in Render menu, no problems here
Looks like blender render can’t use more than 2 Core for some algorithms.
Attaching my blend file, render and render settings for the material that slows down the blender.
How about Yafray ?
