Inventor offers simple, easy to use visualization effects to enable realistic looking models in the viewport. The effects available depend on the capabilities of your graphics hardware, operating system, and the Inventor graphics hardware setting in the
Application Options 
Hardware tab.
The following illustrates the visual effects you can experience at the various Autodesk Feature Levels, and the table below specifies the minimum system requirements for each level.

You can query your system to find your Autodesk Feature Level in two different ways:
- Go to Application Options | Hardware | Diagnostics. The dialog will display the Autodesk Feature Level when using either the "Performance" or "Quality" settings on the Hardware Tab.
- Run the standalone AdskDiagOutput tool from a Command Prompt. It will report the Autodesk Feature Level of your system in addition to other system and graphics hardware related information.
