Awesome engine, I love the natural lighting ray tracing gives. They should fix the HDR range a bit though, too much whiteout going on.
The graininess is not a filter btw, it's the limitations of the hardware for this rendering method. One big advantage is though that the engine never has to drop frames. The picture will only get slightly more grainy under heavy load. The faster the hardware gets the more data points it can trace and the better the pq gets.
I love the part where it flies close by the traffic light and you can see the reflections in the glass.
