Hi Dimitrios, Glad to hear you got it working. I have a couple of further hints for you.
You may find that the accuracy is improved if you use _oldFrame without the increment. The variable name is a little misleading as it is actually stores the id for the current frame, if you look at the update function in FFTOceanSurface it is assigned after the vertices have been updated and is used purely to prevent updates of the vertices if the frame hasn't changed. This does depend on whether you're calling getHeight before or after that function is called. You could also try using a bilinear interpolation between the four closest vertices, There should be to copy the the interpolation function in the MipmapData class which I use to smooth out the vertices for the different mipmap levels.
