After looking more into it, seems like that microstutter existed for ages and mostly noticable when you use Fancy graphics settings paired with low performing Intel HD. Probably a part of how game works at this point and hopefully will be more smoothed out in the future. I do think it degrades playability on low performing PCs, it is quite visible in some cases, like in big forests and near oceans. Using Fast preset helps a lot.

Purely anecdotal: Noticing stronger microstutter since at least world height increase in some scenes (but I don't have solid data to back that up). Can be especially noticed when moving in some biomes (step-like motion stutter), worse near oceans with kelp.
