It's bizarre that neither the README nor the associated minimal site explains what it does in detail, with screenshots or anything. I'm assuming this is a modern version of GDI++, which a decade ago brought Mac-style font rendering to Windows, but stopped being maintained a while ago. For people who aren't aware of the difference, it's essentially that Windows uses heavy font hinting to try to align character strokes…
I never understood _why_ but text rendering on windows has always looked like garbage to me. It was obviously not the screen resolution or anything, because you can run a linux vm (say, on virtualbox) and the text rendering inside the VM will look much better than the text in windows. > Nobody's "right", it's just personal preference. I don't think that's true. macos is clearly better.
I've also noticed certain Windows programs especially installers have their own resolution and it becomes even more apparent.
