To adjust 3D hardware acceleration
From the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Manage 3D Settings to open the associated page.
The options on this "advanced" page enable you to change all the image and rendering settings of your 3D applications that utilize Direct3D and OpenGL technology.
Click the Global Settings tab.
Under Settings, click the setting corresponding to the Multi-display/mixed-GPU acceleration feature and select one of these options:
Single-display performance mode: Specify this setting if you have problems with the multi-display modes.
Note: This mode is faster than either of the multi-display modes described below.
Compatibility performance mode is useful 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.
When this mode is in effect, OpenGL renders in "compatibility" mode for all displays so that when different classes of GPUs are in use, the lowest common feature set of all active GPUs is exposed to OpenGL applications.
Note: The OpenGL rendering performance is slightly "slower" than in single-display mode.
Multi-display performance mode is useful 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.
When this mode is in effect, OpenGL renders in "performance" mode for all displays and when different classes of GPUs are in use, the lowest common feature set of all active GPUs is exposed to OpenGL applications.
Note: The rendering performance is "faster" than in compatibility mode, although switching or spanning displays may result in minor transient rendering artifacts. (责任编辑：)
