I'm waiting for integration into Cinema 4D to replace Vray.
Analyze opportunities Octane, identify strengths and weaknesses.
Here are my tests and developments.
At the moment, almost Octane substitute Vray in architectural visualization. The only thing behind it is that Octane does not support standard procedural shaders (noise, brick, tile) and a system of layers in the texture. Hopefully in the future it will be implemented.
Sorry for my bad English.

perhaps its the compression on your images but they look very grainy - especially considering how long you had them render in PMC.

I have rendered tons of interior images using PMC at 1080HD they always cleanup within 3-5 hours at 8000 samples ( at 580 speed) , that includes complicated lighting systems, refractions etc.

If its not image compression causing graininess then I would trouble shoot your images because they should not be taking 45 hours on a 580.....

I think the problem is that the chandelier is very complicated.
It consists of a glass tube filled with crystals.
And on the side is a small light bulb. Light bounces through the glass numerous times. Luminaires on the ceiling are also made fairly - reflector, a light source and glass.
It turns out that the scene is illuminated by almost caustic.
I hope the code will be in octane bidirectional ray tracing,such complex scenes will be rendered twice as fast.
