Fractional scaling in Windows is still eh, largely because they can’t do a whole lot about icons not designed for that scale. For example in Rhino a bunch of the icons get weird pixel doubling when running 150% because they were designed for 100% and use a lot of 1 pixel wide elements.
It’s honestly the main reason I keep hanging on to my now 10 and 15 year old displays. I’m hoping for a 6k 32" display so I can run true 200%. Dell makes one but they put a stupid webcam forehead on it.
This is the real reason they disappeared - awnings cost money and don’t increase square footage. That’s also why every modern building is a boring box.
We didn’t forget about them, it’s still covered in architecture school. You can even make them look really cool. But they cost money, and that’s a hard barrier to cross.
