This is a simple benchmark that runs the River Pilot Simulator (RPS)
for 30 seconds. The RPS is part of the RiverWeb project. It is the
prototype exhibit that we installed at the Science Museum of Minnesota.
More info here:
The scene is made up of some terrain covered with a large land-usage texture, tree
billboards, a water plane showing a depth texture, a tugboat model, and
river flow vectors. The terrain data was about 4 million triangles.
It was decimated down to ~150,000 and broken up into 256 chunks for
efficient culling. A typical scene has about 30,000 tris.
~6 MB of textures

notes: MXE has only 4 MB texture. It is loading 16 MB of texture per second
which is consistent with 6 MB (scene) - 4 MB (mem) = 2 MB per frame.
Eliminated texture loading. Used scaled-down textures and no tug textures:

notes: trying to stay under the 4 MB limit for this project is hopeless. :-)
