I was quite surprised to see that the image scaling anti-aliasing of Internet Explorer 8 seems to be significantly better than that provided by Chrome and Firefox. The screen-shot below is of google.com's home page of March 17th for Chrome and Explorer, side-by-side. Note the Chrome version has obvious staircases on the left of the image, and rasterization effects at the top:
So my question is:
Is it possible to tweak the image scaling anti-aliasing of Chrome (and/or Firefox) to match Internet Explorer?
There was no difference between the 64-bit and 32-bit versions of Explorer. And there was no difference between Chrome and Firefox. (Using latest versions of all, on a 64-bit Windows 7 machine.)
A side question (and my real interest) is
What benefits, if any, does Nvidia Optimus provide? But my tests are not yet advanced enough to pose this question. But early results seem negative. (Edit: it was kindly suggested that this side question was unrelated, and should be deleted. But I think it provides the motivation of this otherwise-fluffy question.)
