Windows Okay, so this one actually bothers me quite a deal in the Windows 8 consumer preview: the fonts in Metro look fuzzy - they look like fonts on Mac OS X. Because of the Mac OS X resemblance, I had assumed that Metro switched to a shape-accurate rendering method, like Mac OS X uses, but as it turns out, it's a little less exotic than that.

"Sub-pixel rendering makes fonts look wonderful on LCD screens...

As long as the subpixels are horizontally-aligned and RGB ordered.

Turn a screen 180 degrees and your subpixels are BGR ordered, which doesn't look that good with Cleartype.

Turn it 90 degrees and your subpixels are vertically aligned, which looks bloody awful with Cleartype.

Since people are going to be using their tablets any way up Microsoft made the right choice in turning off subpixel anti-aliasing.

Well, no. That isn't what happens. Pixels are still drawn in the same fashion. Use your video driver to rotate the screen 90 degrees. ClearType still works. All that happens when the screen is physically rotated is that the glyps are rotated.. Actual subpixel calculations occur as before. The fonts are rotated, but the rendering doesn't need to be.

ClearType is already capable of rendering correctly to BGR subpixel order. The rare screen BGR screen looks terrible with the default settings, but the ClearType Tuner can be used to fix it.
