Nope, the UI got an update too. It renders at high-DPI on Windows. Chrome on a high-DPI machine looks exactly the same as on a low-DPI machine, except sharper. It used to be plagued with issues, but I'm fairly sure they're all gone now. DirectWrite isn't perfect. It still has weird hinting and kerning at high-DPI with some fonts, but it's better than GDI.

I find Chrome better than IE, actually. IE ignores my DPI settings and scales pages to 250%, so everything looks too large. Chrome renders correctly at 200%.
