First of all... DirectX compatibility is already in Wine... you do NOT need to install DirectX unless there is some major problem where it is fixing it. Often you install just some of the d3dx9 dll files in Winetricks, but never install DirectX or any of the d3dx9 unless you've already tried to run the program and it is failing to run. More often installing full DX9 in Wine will break more things than it will fix.
