Direct3D versions

DirectDraw is an obsolete 2D rendering API from Microsoft that was used by game developers mainly before the release of Direct3D 8.

Determine the Direct3D/DirectDraw version for older games

This section is only applicable for DirectDraw and Direct3D 7 or older. For newer render APIs, use a tool such as MSI Afterburner or Special K.

Identify the render API being used:

Note the following before proceeding with the below instructions: Direct3D 7 uses the following system DLL files: ddraw.dll, and d3dim700.dll. Direct3D 2-6 use the following system DLL files: ddraw.dll, and d3dim.dll. DirectDraw uses the following system DLL file: ddraw.dll. Older games could often combine the use of render APIs, and might use both Direct3D (e.g. 3D rendering) and DirectDraw (e.g. video playback). Use a tool such as Process Explorer to identify loaded DLL files of the game process while the game is running: Does the game make use of d3dim700.dll? This means that the game makes use of Direct3D 7. Does the game make use of d3dim.dll? This means that the game makes use of Direct3D 2-6, and a tool such as dgVoodoo would need to be used to determine the exact version by tracing the API calls. Does the game make use of ddraw.dll only? This means that the game makes use of DirectDraw 1-7, and a tool such as dgVoodoo would need to be used to determine the exact version by tracing the API calls. If you see a game loading both d3dim.dll and d3dim700.dll, you'd need to trace the calls to determine which version is actually used for rendering. You might see some 2D games load d3dim700.dll, despite having 2D graphics. These require a closer inspection of the calls to determine the cause: In some cases Direct3D 7 is used to render certain effects which are not possible with DirectDraw alone. In some other cases, 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 dev tools that added the DLL as a dependency regardless. If dgVoodoo needs to be used, do the following procedure to trace the calls: Some games might refuse to load dgVoodoo's DDraw.dll from their folder. Apply this workaround. Download the debug build (named as (spec release with Debug Layer)) of dgVoodoo2, and also download DebugView or DebugView++. Apply the dgvoodoo 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 DebugView or DebugView++ and keep it running. 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 DebugView or DebugView++. You'd see a long list of interfaces sorted by time. Determine the Direct3D or DirectDraw version using the following tables: There is no Direct3D 4 or DirectDraw 4, since DirectX 4 was canceled and never released. Direct3D version | Interfaces -----------------|----------------------------- 2/3 | Direct3D, Direct3DDevice 5 | Direct3D2, Direct3DDevice2 6 | Direct3D3, Direct3DDevice3 7 | Direct3D7, Direct3DDevice7 DirectDraw version | Interfaces -------------------|--------------------------- 1 | DirectDraw, DirectDrawSurface 2/3 | DirectDraw2, DirectDrawSurface2 5 | DirectDraw2, DirectDrawSurface3 6 | DirectDraw4, DirectDrawSurface4 7 | DirectDraw7, DirectDrawSurface7 Direct3D 2 and 3, and DirectDraw 2 and 3, use the exact same interfaces. As a result they cannot be distinguished by interfaces. For these cases use the DirectX version listed in requirements or readme, or the version of the DirectX installer shipped with the original release of the game. DirectDraw 2/3 and 5 use the identically named DirectDraw2 interface. To distinguish between the two check the name of the DirectDrawSurface interface. If you have trouble determining the exact DirectDraw version, simply write true in the directdraw versions field on the wiki page.
