For discrete data, as in image processing, the most optimal way is to
either use ArrayPlot[] or Raster[]. For continuous data, and if you do
not care about using Interpolation, arbitrary MeshFunctions,
RegionFunction, etc, use ListPlot3D[data,MaxPlotPoints-
>Infinity,PerformanceGoal->"Speed"], the MaxPlotPoints->Infinity will
use all your data, the default value of MaxPlotPoints will downsample.

Also, notice that the visualization functions ListXXX  are vertex
based, which means that you will not get the discreet steps that V5.X
used to produce.
