---

Retrieves device-specific information about a device.

Definition

Visual Basic	Public Structure DeviceCaps
C#	public struct DeviceCaps
C++	public value class DeviceCaps sealed
JScript	In JScript, you can use structures, but you cannot define your own.

Members Table

The following table lists the members exposed by the object. Click a tab on the left to choose the type of member you want to view.

Methods

Method	Description
ToString	Obtains a string representation of the current instance.

Properties

Property	Description
CanDrawSystemToNonLocal	Indicates whether the device supports copying from system memory textures to nonlocal video memory textures.
CanRenderAfterFlip	Indicates whether the device supports queue-rendering commands after a page flip.
CanStretchRectangleFromTextures	Indicates whether the device supports Device.StretchRectangle using a texture as the source.
SupportsAdaptiveTessellateNPatch	Indicates whether the device supports adaptive tessellation of N-patches.
SupportsAdaptiveTessellateRtPatch	Indicates whether the device supports adaptive tessellation of RT-patches.
SupportsDMapNPatch	Indicates whether the device supports displacement maps for N-patches.
SupportsDrawPrimitives2	Indicates whether the device supports DrawPrimitives2.
SupportsDrawPrimitives2Ex	Indicates whether the device supports extended DrawPrimitives2.
SupportsDrawPrimitivesTransformedVertex	Indicates whether the device exports a hardware abstraction layer (HAL) that is aware of DrawPrimitives.
SupportsExecuteSystemMemory	Indicates whether the device uses executable buffers from system memory.
SupportsExecuteVideoMemory	Indicates whether the device uses executable buffers from video memory.
SupportsHardwareRasterization	Indicates whether the device has hardware acceleration for scene rasterization.
SupportsHardwareTransformAndLight	Indicates whether the device supports transformation and lighting in hardware.
SupportsNPatches	Indicates whether the device supports N-patches.
SupportsPreSampledDMapNPatch	Indicates whether the device supports presampled displacement maps for N-patches.
SupportsPureDevice	Indicates whether the device supports rasterization, transformations, lighting, and shading in hardware.
SupportsQuinticRtPatches	Indicates whether the device supports quintic cubic Bezier curves and B-splines.
SupportsRtPatches	Indicates whether the device supports rectangular and triangular patches.
SupportsRtPatchHandleZero	Indicates whether the hardware architecture does not require caching of any information and whether uncached (handle-zero) patches are drawn as efficiently as cached ones.
SupportsSeparateTextureMemories	Indicates whether the device is texturing from separate memory pools.
SupportsStreamOffset	Indicates whether the device supports stream offsets.
SupportsTextureNonLocalVideoMemory	Indicates whether the device can retrieve textures from nonlocal video memory.
SupportsTextureSystemMemory	Indicates whether the device can retrieve textures from system memory.
SupportsTextureVideoMemory	Indicates whether the device can retrieve textures from device memory.
SupportsTransformedVertexSystemMemory	Indicates whether the device uses buffers from system memory for transformed and lit vertices.
SupportsTransformedVertexVideoMemory	Indicates whether the device uses buffers from video memory for transformed and lit vertices.
VertexElementScanSharesStreamOffset	Indicates whether multiple vertex elements share the same offset in a stream.
