RenderCapability::Tier Property
Gets a value that indicates the rendering tier for the current thread.
Assembly: PresentationCore (in PresentationCore.dll)
Note |
|---|
Starting in the .NET Framework 4, rendering tier 1 has been redefined to only include graphics hardware that supports DirectX 9.0 or greater. Graphics hardware that supports DirectX 7 or 8 is now defined as rendering tier 0. |
The return value is one of three possible values:
Return value | Rendering tier | Notes |
|---|---|---|
0x00000000 | 0 | No graphics hardware acceleration is available for the application on the device. All graphics features use software acceleration. The DirectX version level is less than version 9.0. |
0x00010000 | 1 | Most of the graphics features of WPF will use hardware acceleration if the necessary system resources are available and have not been exhausted. This corresponds to a DirectX version that is greater than or equal to 9.0. |
0x00020000 | 2 | Most of the graphics features of WPF will use hardware acceleration provided the necessary system resources have not been exhausted. This corresponds to a DirectX version that is greater than or equal to 9.0. |
The following table shows the differences in graphics hardware requirements for rendering tier 1 and rendering tier 2:
Feature | Tier 1 | Tier 2 |
|---|---|---|
DirectX version | Must be greater than or equal to 9.0. | Must be greater than or equal to 9.0. |
Video RAM | Must be greater than or equal to 60MB. | Must be greater than or equal to 120MB. |
Pixel shader | Version level must greater than or equal to 2.0. | Version level must greater than or equal to 2.0. |
Vertex shader | No requirement. | Version level must greater than or equal to 2.0. |
Multitexture units | No requirement. | Number of units must greater than or equal to 4. |

If the current thread does not have an associated Dispatcher object, one is automatically created.
Available since 3.0
