Direct 3D on Windows Seven and 60Hz

[galloups]

Hi people!
I'm using Windows Seven 32bits at the moment.
I made a little search but didn't find my answer so i'm asking here. As i'm trying to play tatsunoko vs capcom i saw that the build r4986 was one of the best for this game, using D3D plugin for grafics.
But in the setting i just can find OpenGL or software. I assume this is because i'm on seven which use DX10? Is there a way to force it to use DX9 like for pc game?

Also i noticed that my game is cap to 50Hz, and i put "enable pal60" in setting.
My game is PAL version, dunno if it's the cause (is the pal version on wii still cap to 50Hz like on dreamcast?)

Thanks for your answer.
