I recently worked on a 4k 24" monitor (~180ppi) on a 2017 MBP. The text was either too small when rendered at 1x, or the framerate dropped to a crawl when using a scaling option. Everything was rendering at under 60 fps. Plus I could clearly see the rendering artifacts when scrolling, mentioned in the article.
