3D acceleration can improve the running smoothness of some 3D software and games, but it will take up a lot of memory after it is turned on, causing the system to freeze. Some win7 users asked me how to turn off the 3D acceleration function? Let's take a look at the method together.
1. Press the "win+r" key combination to open the run window, enter "dxdiag" and press the Enter key to open the DirectX diagnostic tool.
2. Then switch the interface to "Display" to view, and you can check whether the system has enabled 3D acceleration.
3. Then return to the desktop, press the "win+r" key combination again, open the run window, enter "regedit" and press the Enter key to open the Registry Editor.
4. After opening the registry, expand "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectDraw" in turn.
5. Right-click the "DirectDraw" folder to create a new DWORD item named EmulationOnly.
6. After creation, double-click, and then set the "value data" to 1, click OK to save the settings, and then restart the computer to take effect.
