Hi Michael, It was done with loads of hardcore optimization (every-triangle-counts rule from mesh creation, material sizes, shapes of rooms, architecture to actual Away3D tunning itself. The whole “world” is build on new FPS framework we work on. Its based on MVC. But to answer your question, there are generaly cca up to 1500 triangles to render at one session. whole world consist about 4-5000. We gonna send some more detailed looks how we done all that so stay tuned:)
