Required Direct3D 9 capabilities

For applications to fully access the features of Microsoft Direct3D versions 9_1, 9_2, and 9_3, the user-mode driver must expose certain hardware capabilities. These capabilities are expressed in terms of the D3DCAPS9 structure that is returned by the user-mode driver's GetCaps function. To indicate support of the capabilities, the driver must set these members of D3DCAPS9 to a bitwise-OR of all of the respective flag values:

Note  These requirements also apply:

  • The driver must also set the TextureCaps member to a value of D3DPTEXTURECAPS_NONPOW2CONDITIONAL and D3DPTEXTURECAPS_POW2, or to neither.
  • When the driver responds to an event, where D3DDDIARG_CREATEQUERY.QueryType is D3DDDIQUERYTYPE_EVENT, it must always set the event's BOOL value to TRUE when responding. See CreateQuery and D3DDDIARG_CREATEQUERY.

Minimum capabilities for Direct3D level 9_2

These capabilities must be set in addition to those listed for Direct3D level 9_1.

Note  This requirement also applies:

  • When the driver responds to a z-testing query, where D3DDDIARG_CREATEQUERY.QueryType is D3DDDIQUERYTYPE_OCCLUSION, it must always set the query's UINT value to a non-zero value when responding. See CreateQuery and D3DDDIARG_CREATEQUERY.

Minimum capabilities for Direct3D level 9_3

These capabilities must be set in addition to those listed for Direct3D levels 9_1 and 9_2.
