Rendertime depends on Imagesize ?

[DJ-Studd]

Arrr.... "VRay:: Default Displacement / Edge length" :P

What would an optimal setting be? Is there a min and max that I should use?

Either that, or the setting in the VRayDisplacementMod, depending on which you are using.

It all depends on the desired detail in the displacement mesh, so it's a bit of trial and error. Don't go below 1, for sure

Well its one of those things that depends on your displacement.
So yeah keep lowering it until it start to affect quality then raise it abit.

Or don't use the 'view-dependent' option and set your edge length in whatever units you work in. If it's 10km of grass you're rendering, this will add to the rendertime tough... But for carpets and stuff like that I find the view-INdependant mode to work better and more reliable, especially in animations where you move closer and further away from the displaced object. At least your displacement will look the same at every resolution.
