Guys the video made by Digitalfoundry shows very clearly, with plain empirical evidence, what RT delivers vs non-RT:
It's one of the best example videos I have seen and bear in mind that the RT in CP2077 is still pretty BETA stage compared to what it will be in future games. There is a significant difference in visual realism due to the lighting and shadows, transparency and reflections.
Visual realism isn't reducing the lod at 2M. The game was gimped at launch to reduce vram usage.
Everyone applauding the "realism" of these shadows and reflections really need to take a look at the rest of the game. And static screenshots wont show you how bad it is in areas or how bad the transitions are when it loads in higher/lower detail assets.
