I just tried yesterday's Webkit nightly and it supports hardware acceleration. Mozilla's site runs at about 16fps with Webkit, 5fps with Safari/Firefox/Chrome12, and 16fps with Opera 11.5. This may not be news to anyone and may have been in Webkit for months but this is the first I heard of it...

Of HTML markup? What does that buy us? That's usually not a bottleneck.
What is HW accelerated in Webkit is CSS3 transitions (animations) which is very cool, although not new. Browsers that have not supported CSS3 transitions traditionally animated things using timer based Javascript, which is probably not GPU accelerated, although as you know there has been a lot of work in browser Javascript optimization, maybe it is possible to use your GPU to accelerate some Javascript stuff now, I don't know...
I was just trying to figure out what the original post pertained to, it is rather vague.

That's exactly what I meant.

Looks like accelerated canvas. Lion has this enabled by default.

That makes sense!
That will also help projects like this thing that converts Flash to HTML5/Javascript, I'm assuming also utilizing Canvas:

I'm not entirely sure what is being accelerated, but Webkit runs the Firefox benchmark at a decent frame rate. This isn't something I specifically care about but it's good to see Apple's incorporated HW acceleration and OSX web users won't be left behind because until now only Opera 11 had any HW acceleration. I think the compositing is accelerated...not sure...though the rotating benchmark is much faster (~3x) in WebKit vs Safari.

Fishbowl and Speed Reading scores are still really low in WebKit. If you compare it to Win7/IE9 on the same machine you could cry.

By default Lion Safari does fine at speed reading, 60 fps. It gets about 15 fps on the fishbowl demo. Until you turn Full Page Accelerated Drawing on, then it's a constant 60. That probably won't ship enabled by default and you'll have to turn on the Debug menu, not the Develop menu, to access it.
