Discard your settings

•Click Discard to ignore any unsaved changes and restore the settings that existed when the Catalyst™ Control Center was opened or the last time Apply was used. Discard does not close the Catalyst™ Control Center.

Clicking Discard applies to all features of an aspect, not just the feature in the current view.

Restore default settings

1Move the mouse to the bottom right-hand corner of the window.

2Click Defaults.

Note: Clicking Defaults will restore the defaults for the current view only. Previous settings are not altered and will be saved once you click OK.

API Specific

Use the API Specific dialog to select settings that are exclusively for the Direct 3D® and OpenGL® Application Programmable Interfaces (API). These settings are provided for resolving certain incompatibilities within 3D applications that use one of these APIs.

Use this dialog when you are know which type of API (Direct 3D® or OpenGL®) your 3D application uses, and you want to select a particular API-specific feature.

If you are not sure which API your 3D application uses, consult the documentation of your 3D application.

Set Enable geometry instancing

Geometry Instancing allows the GPU to create multiple objects from a single geometric model, rather than passing an entire new model for each item on the screen. This increases the rendering speed of images such as leaves, or grass.

1From the Tree View pane, expand 3D.

2Click API Specific.

3Select Enable geometry instancing to place a check mark in the check box.
