Unfortunately, doesn't help that much. Tweaking toolbar settings gets me more usable toolbar buttons, but the address bar, buttons around it, menu icons are not good. E.g., compare small icons in file panels (properly sized) and small icons in the address bar and menus - it's supposed to be the same icon size, but they render drastically different.
Do you have hi-DPI screen handy? Check out how Explorer looks like with >100% scaling. It's proportional, small icons do not look tiny, address bar looks fine...
