When using procedural textures (noise, turbuilence etc) with vertex displacement a UWV projection node has to be added to make it work properly (object has UV map). With bitmap textures it is not needed.

You should always use a Projection node when using procedurals.
By default procedurals area applied using the XYZ Projection in World mode. That's always true for any input, not only for Vertex Displacement.
Moreover, to have AutoBump work correctly, you need to also use Local Mode if XYZ Projection is used.

Where is this mode located? I can see only Vector space with Object and tangent modes

XYZ Projection is one of Octane's available projections, not a Displacement option.

Ok, I've found this.
