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 (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 or Special K is recommended.
Identify the render API being used:
|
Use a tool such as Process Explorer to identify the loaded DLL files of the game process while the game is running:
- 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 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 dgVoodoo needs to be used, perform 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 should see a 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.
