This race track has a high level of detail for only using 35,145 polys (80,380 tris) allowing it to be used on hand held devices. All meshes only uses DDS textures.
The track has a custom collision model which gives the track a smooth ride. I used the free tutorial car to create sample video of a car driving on this track. a href="http://youtu.be/nMw0vrtJhPI">Sample Video .
