Pool and Usage for Index Buffers (Windows Embedded CE 6.0)
1/6/2010
You can create index buffers with the IDirect3DMobileDevice::CreateIndexBuffer method, which takes pool (memory class) and usage parameters.
It is possible to force vertex and index buffers into system memory by specifying D3DMPOOL_SYSTEMMEM (see D3DMPOOL), even when the index processing is being done in hardware. This is a way to avoid overly large amounts of page-locked memory when a driver is putting these buffers into AGP memory.
