--- Comment #20 from Roland Haeder roland@mxchange.org --- Thank you for adding it. But I have read that unimplemented functions should return E_NOTIMPL and not D3D_OK. With the native DLL in place I could play for hours but not fully flawless.
If a lot enemies are shooting at you, the sound cracks a lot and framerate drops below playable (2-5 FPS). But maybe that is a side effect of using the native DLL.
This above all was without your added stub. I now recompile and test it after it.
