KB334: How to: Enable GPU hardware acceleration to improve Internet Explorer web content performance
Summary
The FEATURE_GPU_RENDERING enables Internet Explorer (IE) to use a graphics processing unit (GPU) to render content. This dramatically improves performance for webpages that are rich in graphics.
By default, this feature is enabled for IE but disabled for applications hosting the WebBrowser Control. Therefore, in order to take advantage of this feature for Moxie content, GPU rendering must be enabled for Moxie by changing registry keys.
