How does Win7 effectively switch the hardware acceleration function of the graphics card?

Users ask: How to effectively turn off and turn on the hardware acceleration of the graphics card under Windows 7, by modifying the /Acceleration.Level value in the registry, it seems to have no effect, and after the modification, some machines use dxdiag to see It is disabled. Is there any good way?

Usually such settings are provided by the graphics driver. Windows usually only provides the driver with the most basic functions for the graphics card. You can find the relevant settings in the graphics card driver. If there is no relevant setting, it may mean that the graphics card does not support this feature.

In addition, if you use IE9 browser or Chrome browser, you can control whether to enable graphics hardware acceleration in the browser settings. For Office 2010, there are also the same function switches. However, these are only for the software itself and cannot meet the requirements for the entire system setup.
