To make your 3D application look better

From the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Adjust image settings with preview

The options on the page enable you to change the image and rendering settings of your 3D applications that utilize Direct3D and OpenGL technology.
Select the option Use my preference emphasizing: <selected slider setting>

The available settings are:
- Performance offers the highest frame rate possible resulting in the best performance for your applications.
- Balanced offers an optimal blend of image quality and performance. The result is optimal performance and good image quality for your applications.
- Quality is the default setting that results in optimal image quality for your applications.
Move the slider towards the Quality setting to improve the smoothness of the curved and rounded lines you see mostly on the edges of objects in images. This improvement is known as antialiasing, a technique that minimizes the jagged appearance of curved or rounded edges in 3D images. Enabling this option improves image quality but at some expense of application performance.
As you move the slider, you can preview the appearance of the image in the Performance and Quality preview windows on the left side of the page.
If you want, you can click the Pause button to pause the animation in the Preview window. The button changes to Play, which you can click any time to resume playing the animation.
