How do you change settings for DirectX?

To change settings for DirectX, first, open the DirectX Control Panel by typing "dxdiag" in the Windows search bar and hitting Enter. This will display system information and allow you to check your DirectX version. For graphics settings, you typically adjust them through the graphics card's control panel (NVIDIA Control Panel or AMD Radeon Software) rather than DirectX itself. Additionally, specific game settings may allow you to modify DirectX options within their graphics settings menu.
