I just used DebugView++ to trace dgVoodoo2's API calls, and the game tries to access DirectDraw from DLLMain, and since the D3D11 runtime doesn't run from DLLMain to prevent lockups/deadlocks (cuz the loader lock is still held in that function), the game has to be patched to make it work with dgVoodoo2, probably by delaying its initialization somewhere in the code. Since DirectDraw is probably being initialized inside VideoDrvDDraw.dll's DLLMain(), the most likely solution would be to move that function call outside of DLLMain(), but I'm not really sure how to do that in the assembly.

Well, yes, if a game is type-of-DllMain then only patching will help. I don't know if this game already has such a patch.

It doesn't have one, and the other DDraw wrappers don't have the best performance with this game.

I created a DllMain-patch for this game:

Thanks a lot Dege, it works perfectly now, the game doesn't have any slowdowns either 😀 Any chance you could do one for End of Twilight as well? It has the same exact issue.

Yes,

I also included a patched version of dgVoodoo because the released ones freeze at the startup screen. The fix will be included in the next version ofc.
If you want to play this game with forced resolution or a scaling mode other than "unspecified" then you have to enable option GeneralExt\FreeMouse. Otherwise the mouse gets stuck to the left-top corner and you cannot move it at all.

Btw, this patch might be useful for non-dgV usage as well. My native Intel driver also gets stuck in DD initialization called from DllMain just like dgVoodoo.

Thanks a lot again Dege! I'll release your files as a patch on PCGamingWiki and credit you, I patched your patched EXE to work without the CD. I'll take note of those instructions 😀
