--- Comment #4 from cyfer3@googlemail.com --- --> short answer: nope, they sorta abandoned dx9 completely
--> long answer: There are some updates happened lately and it was possible to workaround this by forcing dx9, but doesn't work anymore. Copy/pasting the d3dcompiler_43.dll to *_47.dll fails at the point when the launcher is starting the client right after patching it to a 2.5 mb file (means they ship it now properly). I just assume wine just can't handle dx11 well on STO yet.
