IE9 delivers final Platform Preview

The IETestDrive.com site has been updated with Platform Preview 4 (PP4) of IE9. This is the final preview of the browser before it’s launch so the word to developers is, use this preview to test your current sites on so you can be sure that your sites will shine come the full release later this year. As with previous previews, this has no address bar but you can open any web page by using the Page >Open (or Ctrl O) function.

Along with this release, there are some updated demos so I took the chance to do a side by side comparison showing the advantages of hardware graphics acceleration over software graphics acceleration. For the purposes of this demo I used Google Chrome v5 for a performance comparison but please go visit the site and check out these demos for yourself.

So what you’re seeing there is IE9 using the power of the whole PC to achieve great performance, clearly showing the advantages of hardware acceleration over software acceleration, demonstrating what HTML5 canvas can do when it’s fully accelerated with the GPU.

For more information about the benefits of GPU powered HTML5, see this post on IE Blog:
