--- Comment #7 from tt_1 herrtimson@yahoo.de --- yeah, it was me who filed that bug after poking the dll files randomly.
thing is, the GD3D11 renderer ships some additional third party dll files. Gothic2.exe starts to look in the same dir it resides for dll files it needs, and before the update it picked the wrong X86_64 dll file and got really angry.
GD3D11 upstream now ships with X86 dll file, but it's slightly updated and now asks for CRYPTSP.dll - wine doesn't seem to ship this, and winetricks doesn't offer it. So I copied CRYPTSP.dll from my old Win7 install right into the System Folder of Gothic2 and got a working application.
better solution is propably to remove d3dcompiler_47.dll and reinstall it with winetricks, this doesn't need additional CRYPTSP.dll cause it's an older version of the lib it seems.
