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.
