Chapter 7 Configuring Key ForceWare Graphics Driver Features • Multi-display compatibility mode is available if you have two or more active displays when running in nView Dualview display mode or if you are using different classes of NVIDIA GPU-based graphics cards. Note: When this mode is in effect, OpenGL renders in "compatibility" mode for all displays. In this mode, when different classes of GPUs are in use, the lowest common feature set of all active GPUs is exposed to OpenGL applications. The OpenGL rendering performance is slightly slower than in singledisplay mode. • Multi-display performance mode is available if you have two or more active displays when running in nView Dualview mode or if you are using different classes of NVIDIA GPU-based cards. Note: When this mode is in effect, OpenGL renders in "performance" mode for all displays. As in "compatibility" mode, when different classes of GPUs are in use, the lowest common feature set of all active GPUs is exposed to OpenGL applications. However, the rendering performance is "faster" than in compatibility mode, although switching or spanning displays may result in minor transient rendering artifacts. Trilinear Optimization This option enable you to have full control over trilinear optimizations in Direct3D and OpenGL applications. 1 Make sure the View advanced settings option is selected from the View list. 2 Select Trilinear optimization from the driver settings list. The available slider settings are On and Off as shown in Figure 7.14. • On allows better texture filtering performance with no perceived loss of image quality. You can view the areas of the image that are affected by the trilinear optimization by enabling textures that contain colored mipmap chains that are used in typical diagnostic applications. Also see Table 7.1, "Image Settings and Optimizations" on page 116. • Off disables trilinear optimizations and will result in the best image quality. NVIDIA Corporation 121
