C4 Displacement Slow Render

[PhosTeam]

I have a very basic object with a slight displacement map on it that takes around 5mins 40 to render - if I take off the displacement, it takes 30secs to render.
The image map quality is also set to 512 x 512, is this normal to take so much longer? Using 3 x TITAN x cards on mac C4D.

Hi PhosTeam,
difficult to say without screenshots or an example scene.
What kind of object and what kind of uvs?
Are you using an image texture for displacement or are you using a noise with auto-baking c4d shader option active?

Thanks Beppe.

It is ok, just left it rendering!
I think it must have been the image texture being used as the displacement map, lowered the resolution and had improved the speed by 1 - 2 mins less per frame.
