Zebediah Figura : wined3d: Allow changing settings using a new WINE_D3D_CONFIG environment variable.
Module: wine Branch: master Commit: fdf2995604c3f17d387f18e5da720fa0253da61f URL: https://source.winehq.org/git/wine.git/?a=commit;h=fdf2995604c3f17d387f18e5d... Author: Zebediah Figura <zfigura(a)codeweavers.com> Date: Tue Mar 8 12:39:30 2022 -0600 wined3d: Allow changing settings using a new WINE_D3D_CONFIG environment variable. This can be significantly more convenient than modifying the registry. config_list_get_value() is based on vkd3d_debug_list_has_member() by Józef Kucia.
