Indeed, simply scrolling this demo page in Chrome 9 feels very laggy. Edit: OS X, late 2009 MBP, BUT with the BetterHN tab/iframe on top (other pages are smooth though).
Really? 9.0.597.98 seems to be scrolling smoothly on Win 7 here.
Aesthetics: :D Performance: o_O
I use these with caution on animated pages or large elements; I don't have links to hand, but have lots of anecdotal stories of performance degradation with CSS drop shadows. Just a friendly word of (unbacked) warning to frontend devs :)
Almost works in IE9, that's amazing in itself. But dead in IE8/7 of course. (via browserling) http://img29.imageshack.us/img29/4448/ie9corners.png Hmm, webpagetest shows it works completely in IE9 http://cdn.webpagetest.org/thumbnail.php?width=930&test=... maybe a later release

They actually completely stopped development on IE between version 6 and 7. There was no IE dev team, beyond people patching bugs. Obviously this did not prevent other people doing GPU-acceleration, but the leading player deliberately halting development will and did cause the market to stagnate.
That's not really relevant to the issue at hand, though. Bringing up Microsoft's misbehavior with IE 6 in this context is like bringing up the time a kid cut in front of you for lunch in third grade when you meet him in college.

Yep, Chrome is far better on Windows than OS X. So long as I was using OS X on my MBP I couldn't use Chrome and kept going back to FF - but since switching the machine to Win 7 I can't not use Chrome.

I have not noticed any issues with Chrome on my pro. Am I missing out on performance?
Scrolling was very jittery in general and page rendering/painting was also slower. Not like molasses slow but definitely not acceptable for a Core i7 machine.
With Win 7 which uses only one GPU, the Nvidia one, it is very smooth and fast as I said - definitely wouldn't want to go back.

The fact that you are correct is laughable in this age of GPUs commonly having 512mb+ of dedicated RAM. Think what the latest game engines can do at 60fps, why oh why do our browsers still sweat over a few alpha channels in 2011? EDIT: My galaxy S phone runs Quake 3 at 60fps, flawlessly. MY PHONE RUNS QUAKE 3! Why can't my browser do alpha blending at more than 10fps?
Games do pretty simple things on the GPU. Download textures, then transform them. They do a _lot_ of it, but conceptually the operations are not actually all that complicated or varied, by and large. Browsers have this little thing they have to deal with called "text". Turns out that stuffing reasonable text into a texture and then scrolling it, say, is not something GPUs can do a good job of. This is why games just…

Tesselation, volumetric shadows, depth of field, etc. Can you really say with a straight face that it's not doing anything complicated? And here we are struggling with drop-shadows. I know the problem domains are different, but I can't help but feel completely underwhelmed at the current state of the web when it comes to graphics. Somehow I think there's more to it than "fonts are hard."
