Would be nice if Mozilla could separate the graphics acceleration from the font smoothing, as both come from one key only in about:config, as I dislike the font smoothing. Ah well.
http://ie.microsoft.com/testdrive/ some nice tests for your GPU accelerated browser. I've got Minefield running the GPU acceleration but i've had no luck with the Chrome acceleration :-( set the shortcut and everything but all the accelerated tests are running like a dog and my ION isn't coming out of idle state :-( works fine in Minefield though :-/ any suggestions?
Just a heads up on this setting. I had a problem with the web based help in LOTRO after making this change. Not only was the font fuzzy but it was extremely difficult to select text or boxes and also noticed that to click on buttons I was having to aim lower than the button appeared. Switching this back to false fixed this.
As Mozilla said, the code is in it's very early stages. It was not there in Beta 3, it's new to Beta 4, hence why the feature is disabled by default. This feature is (apparently), so be to be ready with Firefox 4 official release.
New Firefox 4 Beta 5, has GPU acceleration enabled by default. Improved font rendering, but still not exactly there, but somewhat close. I can tolerate this font rendering, but at the long term, it's a nono, hopefully Firefox will continue to improve it's font rendering on the nest version. There is new features in Beta 5, but it's already way too much off topic.
I just downloaded FF4 B5 and now my fonts fuzzy again I tried switching gfx.font_rendering.directwrite.enabled but it's still fuzzy. Beta 6 will be the one
I had the same problem xonar with the line from various websites. I found one in the end that worked for me; --enable-accelerated-compositing I think its the same as the one jsheff had in his post but with an extra - at the beginning.
