this will likely be a case of "disable enhanced pointer precision/gsync+vsync its bad" that just continues to be spouted about ages after having been disproven. Yes disabling smoothing is generally a good thing if it doesnt ework that is even better.
and in regards to it seemingly not working as intended, its bungie we are speaking of they have not managet to implement anything as of yet without causing some game breaking bug so that makes sense to me.
