I’ve been using Google Chrome browser on Windows 7 x64 these days, and it annoyed me how bad the fonts were being rendered. Too light and somewhat pixelated. After a quick search I found some tips, with most fixes revolving around the LCD antialiasing setting, which didn’t work for me. What did the magic was actually installing and configuring an extension named Font Rendering Enhancer.
This extension has only one setting: “font width”. After adjusting it to “50”, voilà, the fonts started looking good. And, of course, allowing it to work in incognito mode.
