Not plausible, temporal aggregation is only a split second.If they are in fast motion it's not enough duration to capture the shadows
It's just that most lighting in this game isn't actual light sources, but pure ambient. So in most scenes, there simply isn't light source to cast a shadow in the first place.
Right, surfaces with noisy normals don't properly interpolate. Similar to what @JoeJ already predicted for high frequency geometry also applies to plain normal mapping.Also, the occasional grain from the non-denoised bits are oddly endearing.
