Internet Explorer team today announced that they have removed the Internet Explorer's legacy visual filters and transitions in IE10's Standards and Quirks modes, noiung their inferior performance compared to their standards-based replacements and their very low usage on the public Web, Internet Explorer 10 in Windows 8 Release Preview.

In a blog post, Ted Johnson, Lead Program Manager, Internet Explorer Graphics, notes, First introduced in IE4, "legacy DX filters are now removed from all document modes for all sites in the Internet zone. The features still remain available in IE10's document modes 5, 7, 8, and 9 for sites in the Local Intranet and Trusted Sizes zones."

"There is no mechanism for a Web site developer to enable legacy filters on their pages," Johnson writes. Our guidance remains the same as stated in Moving to Standards-based Web Graphics in IE10: "Now is the time to make the move to standards-based markup and use IE10's new CSS3 features instead of legacy DX Filters," he said.

End users will be provided with the possibility to change the default rendering of legacy filters in the Security tab in the Internet Options dialog.

"Select the zone to change and touch or click 'Custom level…'. In the Security Settings dialog for that zone, scroll down to the Option 'Render legacy filters' in the 'Miscellaneous' section. There you may enable or disable the rendering of filters for all sites in that zone," Ted Johnson explains.

He also adds that system administrators will be able to control these settings for all people that are using the Group Policy.

"Users benefit when all browsers support the same standards-based markup and all sites serve standards-based content to all browsers. We encourage all developers to serve the same standards markup to IE10 and move your sites off of IE's legacy filter features today," Johnson concludes.
