I just installed Windows 2003, but now I find that many 3D games cannot run. Only some traditional 2D graphic games can barely run, and the speed is very slow. I feel that Windows 2003 is very fast when running PhotoShop, but why can't it run 3D games?
This is not because Windows 2003 does not support 3D games, but a problem with system settings. First, make sure to install the graphics card driver in the correct way, and then turn on DirectX acceleration. DirectX acceleration is the most basic need of 3D games. However, in order to make Windows Server 2003 a more single-sided server-oriented platform application, Microsoft actually turned off its acceleration function by default. Even after installing the latest DirectX 9.0, the acceleration function will not be automatically turned on, but must be set manually. Enter "dxdiag" in the "Start" → "Run" dialog box to open the DirectX diagnostic tool. Then enable DirectDraw, Direct3D, and AGP texture acceleration functions in the display column. This way, Windows Server 2003 can run various 3D games. In addition, Windows Server 2003 also turns off hardware acceleration by default, which you can set to full acceleration in the advanced menu that displays properties.
