DirectDraw versions

DirectDraw is an obsolete 2D rendering API from Microsoft that was used by game developers mainly before the release of Direct3D 8. To determine the exact version of DirectDraw being used by a game, a more in-depth investigation needs to be performed by tracing the API calls with dgVoodoo 2 (see Determine the Direct3D/DirectDraw version for older games).

Determine the Direct3D/DirectDraw version for older games

This section is applicable for DirectDraw and Direct3D 7 or older. Although these methods can be used for Direct3D 8-9, using a tool such as MSI Afterburner is recommended.

Identify the render API being used:

Start by identifing the loaded DLL modules while the game is running: (using e.g. Process Explorer) If the game loads d3d8.dll, use MSI Afterburner to validate if it actually renders using Direct3D 8 or not. If the game loads d3dim700.dll, it uses Direct3D 7. If the game loads the following DLLs, the exact API version cannot be determined based on the DLL alone. A tool such as dgVoodoo 2 must be used to trace the API calls for determining the exact version: If the game loads d3dim.dll, it uses a version in the Direct3D 2-6 range. If the game loads ddraw.dll only, it uses a version in the DirectDraw 1-7 range. If the game loads both d3dim.dll and d3dim700.dll, it uses one for rendering and the other for other purposes. If a 2D game loads d3dim700.dll, despite the 2D graphics, the possible reasons are: Direct3D 7 is used to render certain effects which are not possible with DirectDraw only. The game might not be utilizing Direct3D 7 in any meaningful capacity at all. d3dim700.dll is possibly loaded as a result of a developer mistake, or using developer tools that added the DLL as a dependency by default. Note that ddraw.dll is always loaded alongside d3dim.dll and d3dim700.dll, since Direct3D 2-7 require DirectDraw to be able to function. If tracing the API calls are necessary then do the following: Download the debug build of dgVoodoo 2 as well as DebugView or DebugView++. Apply the dgVoodoo 2 files to the game per the usual method in the guide. In the game folder, run dgVoodooCpl.exe, right-click on the dgVoodoo banner, and enable Show all sections of the configuration. Open the last tab, Debug, and set Maximum trace level to +Additional trace info for internals. Run the downloaded DebugView tool. Make sure its window is empty before launching the game. Launch the game, start a new game and proceed until you reach in-game graphics. Exit the game and check the DebugView window. If done correctly, a list of interfaces sorted by time should be visible. Determine the Direct3D or DirectDraw version using the following tables: Direct3D version | Interfaces -----------------|--------------------------------------- 2/3 | Direct3D | Direct3DDevice ......................................................... 5 | Direct3D2 | Direct3D2::CreateDevice | | Direct3DDevice2 | Direct3DDevice2::SetCurrentViewport | Direct3DDevice2::GetCurrentViewport | Direct3DDevice2::SetRenderTarget | Direct3DDevice2::GetRenderTarget | Direct3DDevice2::Begin | Direct3DDevice2::BeginIndexed | Direct3DDevice2::Vertex | Direct3DDevice2::Index | Direct3DDevice2::End | Direct3DDevice2::GetRenderState | Direct3DDevice2::SetRenderState | Direct3DDevice2::GetLightState | Direct3DDevice2::SetLightState | Direct3DDevice2::SetTransform | Direct3DDevice2::GetTransform | Direct3DDevice2::MultiplyTransform | Direct3DDevice2::DrawPrimitive | Direct3DDevice2::DrawIndexedPrimitive | Direct3DDevice2::SetClipStatus | Direct3DDevice2::GetClipStatus | | Direct3DRampDevice | Direct3DRGBDevice | Direct3DHALDevice | Direct3DMMXDevice | Direct3DMaterial2 | Direct3DTexture2 | Direct3DViewport2 ......................................................... 6 | Direct3D3 | Direct3D3::CreateVertexBuffer | Direct3D3::EnumZBufferFormats | Direct3D3::EvictManagedTextures | | Direct3DDevice3 | Direct3DDevice3::DrawPrimitiveStrided | Direct3DDevice3::DrawIndexedPrimitiveStrided | Direct3DDevice3::DrawPrimitiveVB | Direct3DDevice3::DrawIndexedPrimitiveVB | Direct3DDevice3::ComputeSphereVisibility | Direct3DDevice3::GetTexture | Direct3DDevice3::SetTexture | Direct3DDevice3::GetTextureStageState | Direct3DDevice3::SetTextureStageState | Direct3DDevice3::ValidateDevice | | Direct3DRefDevice | Direct3DNullDevice | Direct3DMaterial3 | Direct3DViewport3 | Direct3DVertexBuffer ......................................................... 7 | Direct3D7 | Direct3DDevice7 DirectDraw version | Interfaces -------------------|------------------------------------- 1 | DirectDraw | DirectDrawSurface ......................................................... 2/3 | DirectDraw2 | DirectDraw2::GetAvailableVidMem | | DirectDrawSurface2 | DirectDrawSurface2::GetDDInterface | DirectDrawSurface2::PageLock | DirectDrawSurface2::PageUnlock ......................................................... 5 | DirectDrawSurface3 | DirectDrawSurface3::SetSurfaceDesc | | DirectDrawColorControl ......................................................... 6 | DirectDraw4 | DirectDraw4::GetSurfaceFromDC | DirectDraw4::RestoreAllSurfaces | DirectDraw4::TestCooperativeLevel | DirectDraw4::GetDeviceIdentifier | | DirectDrawSurface4 | DirectDrawSurface4::SetPrivateData | DirectDrawSurface4::GetPrivateData | DirectDrawSurface4::FreePrivateData | DirectDrawSurface4::GetUniquenessValue | DirectDrawSurface4::ChangeUniquenessValue ......................................................... 7 | DirectDraw7 | DirectDraw7::StartModeTest | DirectDraw7::EvaluateMode | | DirectDrawSurface7 | DirectDrawSurface7::SetPriority | DirectDrawSurface7::GetPriority | DirectDrawSurface7::SetLOD | DirectDrawSurface7::GetLOD Notes There are no Direct3D/DirectDraw 4 since DirectX 4 was canceled during development. The Direct3D table is not complete, however the listed interfaces should be enough to determine the version. In most cases checking Direct3D* and/or Direct3DDevice* is enough. When dealing with mixed usage of interfaces, note the following: Direct3D 2 and 3, and DirectDraw 2 and 3 uses the exact same interfaces, and so cannot be distinguished between. Use the DirectX version listed in the system requirements or ReadMe file of the game, or the version of the DirectX installer shipped with the original release of the game. DirectDraw 2/3 and 5 use the same DirectDraw2 interface. To distinguish between the two check which DirectDrawSurface interface is used. DirectDrawSurface interfaces refer to texture (.DDS) related methods. A game that uses a newer DirectDraw version may not have a need to use the functionality exposed in the newer versions of the texture related DirectDrawSurface interfaces, so if a game for example uses DirectDraw4 combined with DirectDrawSurface2 with no dependency on DirectDrawSurface4, it is safe to assume it uses DirectDraw 6 based on the DirectDraw4 functions. If having trouble determining the exact DirectDraw version, simply write true in the directdraw versions field on the wiki page, though also note the following:
