Direct3D

Force Vertex Processing / Execute buffer

This option has a dual usage: it allows you to make experiments with different vertex processing settings for D3D8/9, or change the execute buffer creation flags.

When setting D3DCREATE_MIXED_VERTEXPROCESSING or D3DCREATE_SOFTWARE_VERTEXPROCESSING, it also trims down the D3DCREATE_PUREDEVICE flag that is incompatible with these two and causes a Direct3D error.

NOTE: Changing this option to software or mixed may help with rendering problems, such as in "Virtual Skipper 5".

Default
hardware video	FORCEHWVERTEXPROC	This setting uses the video card (GPU).
software system	FORCESWVERTEXPROC	This setting uses the system (CPU). Windows 10 Anniversary Update seems to default to software mode which can cause performance issues.
mixed	FORCEMXVERTEXPROC	This setting forces the mixed mode for the vertex processing.

The flags also have the following effects on the execute buffers.

Default
hardware video	FORCEHWVERTEXPROC	The execute buffers are created in video memory.
software system	FORCESWVERTEXPROC	The execute buffers are created in system memory.
mixed	FORCEMXVERTEXPROC	The execute buffers are enabled for creation in both the video and system memory.

Swap Effect

Forces Swap Effect

FORCESWAPEFFECT

This experimental flag forces the selected SwapEffect mode during the CreateDevice/Reset methods. In some cases, it may improve compatibility or performance. You can choose from the following modes:

Discard
Flip
Copy
Overlay
FlipEx

Capabilities

No Ramp Device	NORAMPDEVICE	Suppresses the IID_IDirect3DRampDevice device type in device enumeration (see EnumDevices method).
No RGB Device	NORGBDEVICE	Suppresses the IID_IDirect3DRGBDevice device type in device enumeration (see EnumDevices method).
No MMX Device	NOMMXDEVICE	Suppresses the IID_IDirect3DMMXDevice device type in device enumeration (see EnumDevices method).
No HAL Device	NOHALDEVICE	Suppresses the IID_IDirect3DHALDevice device type in device enumeration (see EnumDevices method).
No TnL HAL Device	NOTNLDEVICE	Suppresses the IID_IDirect3DTnLHalDevice device type in device enumeration (see EnumDevices method).
Fog vertex capability	FOGVERTEXCAP	Forces the usage of vertex fog by pretending that the device owns the D3DPRASTERCAPS_FOGVERTEX capability and misses the D3DPRASTERCAPS_FOGTABLE capability.
Fog table capability	FOGTABLECAP	Forces the usage of table fog by pretending that the device owns the D3DPRASTERCAPS_FOGTABLE capability and misses the D3DPRASTERCAPS_FOGVERTEX capability.
Spoof Adapter Id	SPOOFADAPTERID	Allows to override the values of D3DADAPTER_IDENTIFIER8/9 returned by the Direct3D8/9::GetAdapterIdentifier() methods with custom values held in the file fake_adapters.ini. The file must be located in the program execution folder and by default it doesn't change the values that are not forced expressly. It is possible to specify more adapters by defining multiple rooms [Adaptern] but the spoofing will take place only on existing adapters, it is not possible to simulate the presence of additional ones. The following is an example of the content of this file:

Device type

When set to a selection different from "default", it forces the device type in the D3D CreateDevice methods. Available values are the following:

D3DDEVTYPE_HAL
D3DDEVTYPE_REF
D3DDEVTYPE_SW
D3DDEVTYPE_NULLREF

D3D tweaks

Patch execute buffer	PATCHEXECUTEBUFFER	This flag patches only the D3D version 1 ExecuteBuffer method. It adds an initial execute buffer to force ZBuffer initialization to the D3DCMP_LESSEQUAL value.
Force ZBuffer ON	FORCEZBUFFERON	This flag patches only the D3D version 1 ExecuteBuffer method. Forces the D3DRENDERSTATE_ZENABLE specification to TRUE
Force ZBuffer OFF	FORCEZBUFFEROFF	This flag patches only the D3D version 1 ExecuteBuffer method. Forces the D3DRENDERSTATE_ZENABLE specification to FALSE
Force Dithering ON	FORCEDITHERING	This flag patches the D3D version 1 to 7 SetRenderState method. In the SetRenderState method, it forces the D3DRENDERSTATE_DITHERENABLE specification to TRUE
Force Dithering OFF	CLEARDITHERING	This flag patches the D3D version 1 to 7 SetRenderState method. In the SetRenderState method, it forces the D3DRENDERSTATE_DITHERENABLE specification to FALSE
