OK, code wasn't written with the assumption that users wouldn't such large grids using ShapeDrawable. ShapeDrawable was never meant for high performance rendering, it's meant for just as an easy way of rendering things like sphere, cones and cubes. osgTerrain is the tool for rendering big height fields. The actual problem with handling 380x390 will likely be down to using DrawElementsUShort internally rather than DrawElementsUInt, that later takes more memory and is less efficient when you have less than 2^16 vertices.
