World Streamer is a memory streaming system, you are able to stream whole your game from a disc in any axis and space. You are able to create endless, looped space games, 2D platformers, 3rd person, without loading screens during player movement. Scenes are as big as you want, without any limits. You could also separate your world into layers like: lighting, ai, geometry etc. Thats will save your cpu,gpu power and you will only load them if they are necessary. Ring streaming will replace your unity terrains by low poly meshes in far distance.
