RTSS is the go-to tool for detecting graphics APIs; the problem is, it can only detect D3D8 and higher.

Since games using D3D7 and older rely on DirectDraw to present the final result, RTSS detects them as DD (DirectDraw ).

Is there a way to determine the D3D variants in old games?

PCgamingwiki has some listed (I know you asked for a method, but it depends what your end goal with this information is). EDIT: Seems I was onto something here 😁
https://www.pcgamingwiki.com/wiki/List_of_DirectX_2-7_games

If the game works with WINE, you can use WINEDEBUG environment variable to trace what's happening:

Note though, that's only one way to do it and probably kjliew has some better ways in his back pocket...maybe something better suited for Windows use? 😁
Hmm, can this be readily seen just by taking a look at the import tables? EDIT: Nope...or at least I don't know how to interpret that...

In the WINE source, check dlls/ddraw/ddraw.c (search for vtbl or Vtbl there). They are just simple tables for each D3D version, so don't worry about not knowing the code.

Why would you want to know?

I, and others, are trying to clean up the direct3d information on PCgamingwiki, specifically for old games.

I could perhaps rely on system requirements, but tracking down original, official requirements is time consuming and in some cases not easy. They could also be unreliable for lesser known games, and open to debate.

Being able to check the d3d version directly would help immensely. It would provide concrete proof of the d3d version that can be trusted.
