Determining Hardware Support

Microsoft® Direct3D® provides the following functions to determine hardware support.

IDirect3D8::CheckDeviceFormat

Used to verify whether a surface format can be used as a texture, whether a surface format can be used as a texture and a render target, or whether a surface format can be used as a depth-stencil buffer. In addition, this method is used to verify depth buffer format support and depth-stencil buffer format support.

IDirect3D8::CheckDeviceType

Used to verify a device's ability to perform hardware acceleration, a device's ability to build a swap chain for presentation, or a device's ability to render to the current display format.

IDirect3D8::CheckDepthStencilMatch

Used to verify whether a depth-stencil buffer format is compatible with a render-target format. Note that before calling this method, the application should call CheckDeviceFormat on both the depth-stencil and render target formats.
