[. . . ] Moving the slider to the left emphasizes a high performance solution while still providing good visuals. Custom Settings checkbox Anisotropic Filtering checkbox Anisotropic Filtering slider Anti-aliasing checkbox Texture Preference slider 15 This will allow you to choose the texture quality of the mipmaps the application will use. Mipmaps are a collection of different sized textures of the same image. As the user moves closer to a 3D object the image quality should increase, requiring a higher quality texture of the same image. The base mipmap is the highest quality texture, and all subsequent mipmaps are smaller sized textures of the same image. Moving the slider to the right selects a higher quality base mipmap, delivering the highest quality application experience. Moving the slider to the left selects a lower quality mipmap, delivering the highest application performance. Wait for vertical sync will lower the frame rate of full screen games but reduce the image tearing that can occur with the higher frame rate. Selecting Application Preference allows the application to decide whether or not it should display its frames at the refresh rate of the monitor. Selecting Always Off allows the application to run at its highest possible frame rate, regardless of the monitor's refresh rate which is typically less than the frame rate at which the application will run. This button allows you to access advanced settings that can solve compatibility issues for a few specific Direct3D® applications. This button allows you to reset the Direct3D® settings to default values. Mipmap Detail Level slider Wait for Vertical Sync Compatibility Settings button Defaults 16 Direct3D® Compatibility Settings Support Wbuffer This will enable W-Buffer support for 3D games. It is recommended to disable this for games that do not support this feature. Certain applications require the increased precision of W-Buffering and will exhibit artifacts unless the W-Buffer is enabled. Very few applications require a 32 bit ZBuffer, so in most cases this feature should be disabled. Support 32-bit Z-buffer depth 17 When applications use both dithering and alpha blending, visual artifacts can occur. This option allows you to select how the application should handle both features at the same time. In most cases Error Diffusion will handle this situation quite well, but there are a few cases where selecting Ordered may be necessary. There are a few applications that can only support a limited number of texture formats. By selecting Disabled, the driver will not support DTX texture formats, thus reducing the number of texture formats supported. This may eliminate problems with some D3D games which display vertical and horizontal lines around textures, or text that appears incorrect. However, this setting should only be used if you are experiencing the symptoms mentioned, as it may cause problems with other games. This button allows you to reset the Direct3D® Compatibility Settings to default values. Alpha dithering method Support DTX texture formats Alternate pixel center Defaults button 18 OpenGL® Control Panel Using this control panel, you can optimize the display settings for your OpenGL® games. Main and Custom Settings In the Main Settings you can maximize overall performance by moving the slider to the left, or you can enhance overall image quality by moving the slider to the right. 19 Main Settings slider This allows you to emphasize what kind of application experience you'd like to have. Moving the slider to the left will maximize application performance, while moving the slider to the right will provide excellent 3D image quality. [. . . ] Click OK or Apply to save the changes. Using and Adjusting TV Out For information about how to use TV display, right click the ATI taskbar icon, point to Help, then point to ATI Television Display. 29 Using a Monitor vs. Using the TV Display Using your TV for your PC's display is ideal for playing games, giving presentations, watching movies, and browsing the Internet. This occurs because the display adjusts to fit the dimensions of your TV. To correct the monitor's display, use the monitor's control buttons to adjust its display size and position. [. . . ]
