Bad font rendering Chrome
This is an issue with Chrome rendering engine but it looks like this is finally going to be fixed. See https://plus.google.com/u/0/+FrancoisBeaufort/posts/PGPpiQr6bwi
The issue is on Chromium's bugtracker:https://code.google.com/p/chromium/issues/detail?id=333029https://code.google.com/p/chromium/issues/detail?id=25541
EDIT:
The DirectWrite support which enables pretty font rendering has been added to Chrome 37.(source: https://code.google.com/p/chromium/issues/detail?id=25541#c152)
This is an issue with Chrome itself. The problem only exists on Chrome for Windows. Macs and Linux users of Chrome don't have this problem. There's nothing you can really do about it.
Have you tried adding this CSS to the Chrome one?
-webkit-font-smoothing: antialiased
Give that a shot and see if it helps.
