In my observations it’s the reverse. Windows font rendering looks ok to me (if a bit “off”) on my laptop with 1.5x UI scale, but underwhelming at 1.x. At 1.x fonts look badly kerned and a bit misshapen, and that cleans itself up quite a bit at 1.x and beyond. macOS and Linux rendering looking better to me regardless of render scale. Good kerning and no beating font glyphs into odd shapes to fit a pixel grid on screens with pixel density high enough that it isn’t necessary (we’re not running 1024x768 LCDs any more).
