However, there were competitors such as OpenGL, which earned a good reputation. Although it got off to a slow start, the popularity of downloading DirectX began increasing. Thus, in June 1996 the first version of DirectX was born, available for Windows 95 and NT 4.0. Letting applications perform other processing with busy present queues.But always quick to detect the needs of the user, Microsoft found a way to offer game developers a tool for direct access to hardware resources in Windows. For more information, see Imposing Requirements on the D3dDrawPrimitives2 DDI. Querying asynchronously imposes two new requirements on the D3dDrawPrimitives2 DDI. For more information, see Verifying Support of Query Types. Reporting support of asynchronous query operations, even if the driver just responds by indicating that no query types are supported. Setting the D3DFORMAT_OP_BUMPMAP flag in the dwOperations member of the DDPIXELFORMAT structure for all surface formats that can support bump mapping in either fixed-function or programmable-pixel pipes.

The driver must continue to report only DirectX 8.0 related capabilities in D3DCAPS8 when queried by the DirectX 8.0 runtime. D3DCAPS9 contains both DirectX 9.0 and DirectX 8.0 related capabilities. Support of this request is described in Supporting GetDriverInfo2. The driver returns a D3DCAPS9 structure in response to a GetDriverInfo2 request using the D3DGDI2_TYPE_GETD3DCAPS9 value similarly to how it returns a D3DCAPS8 structure as described in Reporting DirectX 8.0 Style Direct3D Capabilities. Reporting the capabilities of its device by returning a D3DCAPS9 structure when requested. Supporting Commands for Setting Render TargetĪ DirectX 9.0 version driver must support:

Reporting Support of UBYTE4 Vertex Element However, for a driver to be loaded by the operating system as a version 9.0 driver, it must implement the features that are described in the following sections: The DirectX 9.0 runtime will supply hardware acceleration if the display driver is a DirectX 7.0 or later driver.
