This is to measure the difference.) Yep, looks better than the previous run and also a bit better or on par with the initial run I did. The thing is, I'm not sure whether optimizing the thing for each uarch is a workable solution software-wise or maybe having a single version which performs sufficiently ok on all uarches is easier/better to maintain without causing code bloat.
