Each point is where a Ray hits a surface, so to achive real-time framerates they just simulate as many rays they can in the target frametime. when everything is static they can use the previous frame's traces to fill out the image, but when anything including the camera moves they have to do all new traces. They are working on filtering to better blend the points to reduce the grain but basically they are banking on computing power to allow them to brute force through the problem. Hence it being a primarily a Cloud rendering API.
