Use the <span style="font-weight: bold">API Specific</span> 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.

<p class="pBody">
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.

<p class="pBody">
If you are not sure which API your 3D application uses, consult the documention of your 3D application.

This option enables support for DirectX« compressed texture formats. DXT requires half the amount of memory to draw the same amount of textures. This frees up memory while achieving high quality graphics.

This setting may eliminate problems with certain Direct3D« games that display vertical and horizontal lines around textures or display text incorrectly. This setting should only be enabled if you are experiencing these issues, as it may cause problems in other games.
Enabling Triple buffering will improve the frame rate of games when vertical sync is enabled, only if the frame rate is less than the vertical sync refresh rate. In low memory situations, enabling Triple buffering may decrease application performance as there will be less frame buffer memory available for texture and geometry data. If there is insufficient memory available to support Triple buffering, it will automatically be disabled.
