Microsoft has made the final Internet Explorer 9 Platform Preview available over here. This new release shows off fully hardware accelerated HTML5 graphics and improvements on industry standard tests, including a 95/100 score on the Acid 3 test.
According to Microsoft General Manager, Dean Hachamovitch, this release demonstrates the potential advantages of fully hardware accelerated HTML 5 graphics. Platform Preview 4 also demonstrates great performance improvements on industry standard tests. IE 9 Platform Preview 3 received a score of 88/100 on the Acid 3 test while PP4 scores 95/100. The remaining points that are missing involve the SVG fonts and animations that are currently being transitioned.
In preparation for the upcoming beta (currently scheduled for September), Microsoft is asking Web Developers to begin coding their sites according to the web standards rather than testing for IE versions. Hachamovitch stated that the IE 9 platform is nearly complete and therefore, ready to be tested publicly.
