The default settings for displacement is view dependant - ( displaced edge size depend on view ).
never really understood what this means.
To displace a mesh it's subdivided by V-Ray. Default settings in V-Ray is to adjust the subdivision based on the view. So mesh closer to the camera is subdivided more than mesh further away.

does that mean I should create different groups with each face? Or that its enough that I divide the faces with lines? Meaning that instead of using a 10x10 meters face, its better that I use a 10x10 meters MESH made of several 25cm sized triangles?
Displacement eats up memory. If you have a large face V-Ray must hold on to memory for that entire face all in one chunk. But, if you split it into smaller pieces V-Ray can let go of some of the memory once it has processed each of the smaller pieces.
You can find tips and hints if you search for displacement and memory management. I'll probably explain it better than what I can do.
And I think (I might be making it up π ) that V-Ray prefer triangulated mesh for displacement.
