I actually don't think Blender does "full ray tracing" exactly either, or at least at some point it didn't. At least to the point where you do get some rasterization artifacts, like being able to see the polygons on the edge of objects. That's probably about as good as you can get. Combined with a "nanite" like technology, it's probably not much of a problem.
