I spend a lot of time doing lighting TD work using non-realtime renderers. Every one of those examples is pretty good for realtime, but also looks soooo wrong! its not anywhere near the same quality as a proper raytracer!
-Thats not what an ao pass should look like. But you shouldnt even need ao if your GI/shadows look good
- Gi should have detail to it, every realtime example is sooooo blurry
-The screen space reflections sometimeslook ok but really depends on your scene, you get all sorts of reflections in the wrong place.
-Yucky DOF without the nice bokeh on highlights and all those edge problems you get with a z-space blur.
The beauty of raytracing with a unified sampler is it makes the algorithm for each of these features you listed incredibly simple and it mixes distributes CPU/GPU time to whats important depending on that part of the image.
scene with lots of motion blur- more primary samples, less samples to gi/shadows/reflections - automatically based on how much gi/shadows you see
scene with lots of gi - more samples in gi, less for reflections etc - automatically
You can have a complex scene with reflections/gi everywhere, and then turn a heavy DOF on and get faster frame times.
