I don’t believe they’ve changed it, but tbqh I swap back and forward daily from my MacBook to my gaming PC over the same DisplayPort connection, both set at 150% display scaling (basically), and for where I’m sitting I can’t tell the difference — and there are heap more UI elements on Windows (various icons, apps, etc) that look way way worse due to not being compatible, or having hi-res assets perhaps?
It does however run a tiny bit slower due to that non-integer retina scaling.
