You configure the current display driver using the Viewports panel of the Preference Settings dialog.
Changes to a driver's configuration take effect immediately, and the configuration persists between sessions of 3ds Max. However, data downloaded to the graphics card is not regenerated. For example, if you change the resolution of a texture, the GPU continues to use the previous resolution until you use the Material Editor to reload the texture.
The options in the driver configuration dialog vary, depending on which driver is in use. This section describes the options for the Configure Software Display Driver dialog, Configure Direct3D dialog, and Configure OpenGL dialog. Options for the Nitrous driver appear on the Viewport Configuration_dialog.
