Acceleration is a new feature introduced in IE9 that enables hardware acceleration to be applied to every content on a Web page, including text, images, backgrounds, borders, SVG content, and HTML5 video/audio, primarily using the Windows DirectX Graphics API. The results are most obvious when you play high-definition or hyper-clear video, in the traditional mode, when playing this video, the average CPU usage will be significantly increased, mainly in our use of computers will feel that the computer will be very large, the system becomes very card, and in the IE9 this kind of hardware acceleration help, The GPU will be fully utilized, the CPU will be released, we can watch the video smoothly, do not worry about the CPU overheating this problem.
Obviously, hardware acceleration is a good thing ah, but sometimes because of our misoperation, or because of some virus damage, will lead to this function lost its original effect. The general performance of the IE9 "use software rendering without GPU rendering" option suddenly disappears. So how to solve this situation in general? Let's introduce you.
Tip: There is a risk of modifying the registry, please back up your data in advance and carefully operate under the guidance of a professional person.
Generally this situation is the registry has been modified, first of all, we open IE Registry, windows+r, and then input regedit, enter sequentially expand Hkey_local_ Machinesoftwaremicrosoftinternetexplorer
This is about IE in the registry, ie related settings are generally in this area. We suggest that you can back this up. The method is simple, right-click, and then select Export.
Hardware-accelerated registry settings also need to expand Advancedoptionsaccelerated_graphicsuseswrender, where CheckedValue is a hardware-accelerated switch with a value of 1 indicating that hardware acceleration is turned on, A 0 statement indicates that hardware acceleration is turned off.
Where the type value defaults to a checkbox, which is the check box. If you turn this value into empty or remove it, then the hardware acceleration option will disappear. What we're going to fix is simple, and it's OK to manually restore this value. Then you can restart the browser.
