Bad font rendering Chrome

Question

How i fix this?

First "D" is rendered on Chrome 31.0.1650.63 m and second is rendered on IE11.

Update:

adding -webkit-font-smoothing: antialiased; the problem remains...

It could be a problem with the video card?

Update 2:

css font code:

 @font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 300;
  src: local('Open Sans Light'), local('OpenSans-Light'), url(../font/font1.woff) format('woff');
}
@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 400;
  src: local('Open Sans'), local('OpenSans'), url(../font/font2.woff) format('woff');
}

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=333029 https://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)
