> The way we always have before we got enough GPU to make everything look like a movie
Actually I think motion blur is more of a (futile) attempt to hide low frame-rates because we don't have enough GPU to render the ever more demanding scenes.
I think the only thing I can say here is - I dont see anything weird when I turn my head, and when FPS games added blur to "character moves his own body", it felt much less natural, not more. So, to answer question a few posts up "how would we do it?" I'd just say "The way we always have before we got enough GPU to make everything look like a movie"
