Emulating State Blocks
To enable the Microsoft Direct3D runtime to emulate state blocks, the registry can be configured in the following way:
KeyPath : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D KeyValue : EmulateStateBlocks ValueType : REG_DWORD ValueData : 1 for D3D runtime emulation of stateblocks, 0 for driver implementation (default).
Note After the registry is configured to turn on emulation of state blocks by the Direct3D runtime, the runtime does not call the user-mode display driver's StateSet function to set any state-block information.
