--- Comment #28 from Shmerl shtetldik@gmail.com --- Created attachment 51068 --> https://bugs.winehq.org/attachment.cgi?id=51068 Registry fix to disable vertex shaders
Thanks to Ganni1987 from GOG forum who found a workaround for this old bug with disabling vertex shaders.
In HKEY_CURRENT_USER\Software\Wine\Direct3D create MaxShaderModelVS (type of DWORD) and set it to 0 (for details about shaders settings, see http://wiki.winehq.org/UsefulRegistryKeys ).
See attachment for easy reg file to import.
